How can I enable or disable OWA for a specific mailbox?
Using Exchange Management Shell, OWA access can quickly be enabled or disabled for users.  To enable OWA access for a specific user type: Set-CASMailbox -Id This e-mail address is being protected from spambots. You need JavaScript enabled to view it OWAenabled -$true To disable OWA access type: Set-CASMailbox -Id This e-mail address is being protected from spambots. You need JavaScript enabled to view it OWAenabled -$false

Remember to replace This e-mail address is being protected from spambots. You need JavaScript enabled to view it with the user’s email address.
When creating a Personal Distribution List (PDL) the following error occurs: The list you are trying to save exceeds the maximum size limit for distribution lists allowed by your organization. Reduce the number of members and try to save again.
Personal Distribution lists have a default of approximately 100 – 130 members.  To avoid exceeding the limit, take a look at the three potential workaround:
  • Create more than one PDL
  • On the server, create the Distribution Group in Active Directory for large lists
  • On the server, increase the PDL size limit using Exchange Management Shell:
    Set-TransportConfig -MaxRecipientEnvelopeLimit unlimited
After enabling RSA SecurID two-factor authentication, users get multiple login prompts and cannot login to OWA, how can I fix this?

Additional login prompts are often the result of incorrect authentication settings.  For RSA SecurID two-factor authentication interoperation with a Client Access Server (CAS), the owa virtual directory must have Integrated Windows Authentication enabled and Anonymous Access disabled. 

To verify these setting on the CAS,  

  1. Launch the IIS Manager (Start/Run/inetmgr).
  2. Navigate to Web Sites\ Default Web Site\owa.
  3. Right-click on owa and select Properties.
  4. Select the Directory Security tab.
  5. Under Authentication and Access control click Edit.
  6. Uncheck the Enable Anonymous Access option.
  7. Check the Integrated Windows Authentication option.
  8. Click Apply and OK to save the changes.
  9. Restart the IIS service (Start/Run/iisreset /noforce).
 If further login issues occur, we recommend contacting the RSA support team.
How can I ensure user accounts are locked out of OWA after multiple incorrect password attempts?

The Account lockout duration, Account lockout threshold and Reset account lockout counter after settings are configured in the Default Domain Policy.  These settings define what will happen if a user attempts to logon to the domain using the incorrect password multiple times.  Attempting to logon to OWA with an incorrect password will also increase the bad password count (badPwdCount), which will eventually lock a user out of the domain until it is reset.  

Important consideration: Attackers can also use this strategy to lock users out of the network as long as they obtain valid usernames. The default settings of these Default Domain attributes are as follows: 

 

Value DefaultRecommended
Account lockout durationSpecifies the number of minutes a locked out account will remain unavailable before a user can attempt to log back in
Note that such a configuration will likely increase the number of calls that the help desk receives to unlock accounts locked by mistake.

How can I configure the OWA login page so that users do not have to enter the default domain name?
OWA 2007 provides the option to pre-configure the Default Domain in the Exchange Management Console (EMC) so users do not need to enter it.  With this configuration, users only need to enter the logon name and password to authenticate via the Exchange Forms Based Authentication form.  To predefine the default domain,
  1. Open the EMC and navigate to Server Configuration\Client Access and click on the Client Access server.
  2. Right-click on the OWA folder and select Properties.
  3. Move to the Authentication tab
  4. Under the Use forms-based authentication option, select User name only.
  5. Enter the domain name in the logon domain field.
  6. Press Apply and OK to save the changes.
  7. Reset IIS by running iisreset /noforce from the run command prompt.
Accessing an attachment using Microsoft WebReady Document Viewing gives an error indicating that the document cannot be converted because it is larger than the maximum size limit. How can I change the size limit?
When a user clicks on the Open as Web Page link to view a supported file attachment which exceeds the default WebReady Document Viewing file size limit, Outlook Web Access will display the following error:
The document cannot be converted by the WebReady Document viewing service because it is larger than the maximum size limit set by the administrator for your organization.
To alter the WebReady Document Viewing file size limit,
  1. On the Client Access Server (CAS), open the registry editor (regedt32.exe)
  2. Navigate to HKEY_Local_Machine\System\CurrentControlSet\Services\MSExchange OWA
  3. Right-click on MSExchange OWA and create a new Key called WebReadyDocumentViewing
  4. Under WebReadyDocumentViewing , create a DWORD with value MaximumDocumentInputSize
  5. Set a value to the desired size e.g. 10240 kb = 10MB
  6. Under WebReadyDocumentViewing , create a DWORD with value MaximumDocumentOutputSize
  7. Set a value to the desired size e.g. 10240 kb =10MB
  8. Restart the World Wide Web Publishing Service for the changes to take effect

Why do appointments created in OWA not appear in the calendar when using desktop Outlook? Delegates can see the appointment.
Some users may have cached Exchange mode enabled.  In this configuration, Outlook works from a local copy of the user’s mailbox which is refreshed periodically.  This would explain why they can see appointments in their calendars from OWA but not from Outlook.  For more information about the cached Exchange mode, refer to Microsoft’s article: 

 

Setting Up Outlook 2003 Cached Exchange Mode Accounts

http://office.microsoft.com/en-us/ork2003/HA011402591033.aspx

If you are interested I giving users access to shared calendars from within OWA, like they do in Outlook, there is a company called Messageware that offers shared calendaring in OWA.   

How can I paste / embed images in to OWA messages?

Pasting images into messages is not an OWA feature.  There are two workarounds to getting images into your message:

  1. You can paste HTML links to images, but this means that the image needs to be stored on a public server.  An example of this would be when you copy an image from a website and then paste it into an OWA message
  2. You can embed images using Outlook, which actually stores images as attachments, making them available for recipients using OWA to see.

There is a Microsoft knowledgebase article, available below, which explains how to paste an image into the OWA signature.  The workaround does not always seem to work and is not supported by Microsoft as an official solution.

How to get an image into the signature file in OWA

I found my documents in the local browser cache! How can I increase attachment security?

When you open an attachment, rather than view it with WebReady Document Viewing or save it to a specified location, the attachment will always be saved to the temporary internet files folder on the local computer.  This happens unknowingly to the user creating a real danger on computers where unauthorized people could get hold of confidential documents.

There are a few ways Administrators can secure attachments for all:

Disable access to all attachments
Although not practical, it is the safest way to make sure that attachments are never left behind.

Allow access only to files supported by WebReady Document Viewing
Although limited to 4 file types (Microsoft Word, Excel, PowerPoint, and Adobe PDF), this option is more convenient than the first.

Force WebReady Document Viewing and Force Save for all other file types
This is a good option if your company is okay with users saving files to local machine and possibly forgetting to permanently delete them. 

Get third part help
Messageware (
www.messageware.com) offers a product called AttachView which gives Administrators a wide variety of configuration options for securing attachments.  Because AttachView support viewing over 300 file types as safe HTML pages, they really make it feasible to turn off the open and save attachment options for users while they are not in the office or on corporate devices.   

Free Fix for Microsoft Update Q911829

Many companies who have Microsoft Exchange with the update Q911829 (released in March and April, 2006) installed and are using Outlook Web Access have been experiencing a problem addressing messages. In some environments, when the spacebar is pressed after addressing a message the address dialog box re-appears and in some cases, while typing the message body, entering a space suddenly activates the addressing dialog box.

There is a free fix available from Messageware, a company that specializes in OWA enhancement software. This patch is now available to companies and Exchange administrators who are running any version of Exchange or OWA.  It can be downloaded at http://www.messageware.com/downloads/fixQ911829.php

When creating a Personal Distribution List (PDL) the following error occurs: The list you are trying to save exceeds the maximum size limit for distribution lists allowed by your organization. Reduce the number of members and try to save again.
Personal Distribution lists have a default of approximately 100 – 130 members.  To avoid exceeding the limit, take a look at the three potential workaround:
  • Create more than one PDL
  • On the server, create the Distribution Group in Active Directory for large lists
  • On the server, increase the PDL size limit using Exchange Management Shell:
    Set-TransportConfig -MaxRecipientEnvelopeLimit unlimited
How can I see my mailbox size and how much space I have?

Why is OWA defaulting to the Light version even though I did not check the option on the logon page?
If you are using OWA 2007, check to see if you accidently have the Accessibility mode enabled which always uses the OWA light version. To check,
  1. Login to OWA and click on the Options link at the top right side of the page.
  2. Select General Settings.
  3. Under the Accessibility heading verify if the accessibility option is checked.
If this option is not checked, consider the following:
  • Are other people in the company having the same problem or is it only happening on your computer?
  • What browser are you using?  Remember that only Internet Explorer 6.0+ uses the Premium OWA version.
Why are all my emails transferred from my OWA inbox to my Outlook inbox when I opened Outlook? My OWA inbox is empty after using Outlook.

Your Administrator seems to have setup the POP3 or IMAP service on the server.  These services hold emails on the server until you connect using Outlook.  All emails are then pulled down to your desktop leaving your Inbox empty.

 

OWA connects to the mailbox on the server showing you all of your new emails since the last time you connected using Outlook.

 

If you do not want your emails to be downloaded each time, ask your helpdesk if you can set up an Outlook connection directly to the Microsoft Exchange Server, not using POP3 or IMAP.  Note that you can only set up this type of connection while you are in office.

 

For more information on POP3 read:

http://searchexchange.techtarget.com/sDefinition/0,,sid43_gci212805,00.html 

 

For more information on email accounts see:

What is the difference between Reply, Reply to All and Forward?

The reply and forward buttons are ways to respond to messages.  The reply button allows you to send an email back to the person who sent the email.  The forward button allows you to send the email to someone who was not in the TO, or CC lines of the email. 

For example, if you get an email from John who included Jim and Nancy in the CC line:

  • Use Reply (Reply Button) if you want to write back to John about the email.
  • Use Reply to All (Reply to all button) if you want to write back to John and let Jim and Nancy see your response.
  • Use Forward (Forward button) if you want to send John’s email to Amanda, to let her know what John written.

What is the BCC line for?
BCC stands for Blind Carbon Copy which lets you send a copy of your email to someone without letting people in to TO and CC fields know that this person is also receiving this email.  You may choose to put an email address in the BCC field if:
  • you do not want others to know the email address
  • you do not want others to know that you are letting this person know of the communication
  • you are sending a public email and do not want people to get each other’s email address
  • you are working with a third party and do not want the parties to contact each other
How can I troubleshoot not being able to login to OWA?
There could be many reasons why you are not able to login to OWA.  Here is a list of things to check: 
  1. Check the OWA address is correct
    When incorrect, you may see a page cannot be found or Internet Explorer cannot display the webpage error.  You will also not see the login screen or prompt
  2. Check your username and password
    When incorrect, you will be prompted to re-enter your password several times in a row without getting access to your mailbox.  After three tries you will see an error indicating that you are not authorized.
  3. Try accessing OWA using a different browser
    If you cannot get into OWA, try connecting to OWA using another browser.  For example, if you are using Internet Explorer, try using Firefox or Netscape and visa versa.
  4. Try accessing OWA using a different computer
    Go to another computer and try logging into OWA using your account, Can you connect?
  5. Ask you coworkers if they can connect to OWA
    Check with the people around you to see if they are also having problems.
  6.  Document any errors you get and provide all the information to your Corporate Help Desk or Exchange Administrator for assistance
    To take a screenshot of any errors you get by pressing the “Print Screen” button on your keyboard.  Once you press the print screen button the picture will be on your clipboard.  Open a Microsoft Word document, right-click on the whitespace and press Paste

    Gather up as much information about what you are seeing so that you can provide it to your Help Desk or System Administrator.
How can I access my email from home using Outlook 2007?

You will need to speak to your Exchange Administrator about setting up a VPN or RPC over HTTP connection for you.  Refer to the Microsoft knowledgebase article below for more information.   

 

Description of the configuration options for the Exchange over the Internet feature in Outlook 2007 and in Outlook 2003

How can I copy a message folder from one mailbox account to another in a different domain using OWA?

The Outlook Web Access client does not provide a way to backup email folders; you will need to use Microsoft Outlook or Microsoft Outlook Express to create a PST / Data file that will be saved to your computer.   

If you are working from a remote location your Exchange Administrator will need to provide you access to your mailbox via a VPN connection or RPC over HTTP.  Once you set up your account using Microsoft Outlook, you can refer to the link below for more information on how to create an Outlook Personal Folder (.pst).

How to create a .pst file in Outlook 2003 

Note: If you are using Microsoft Outlook 2007 you will use the File\Data File Management option.

OWA ATTACHMENTS back to top

Which file types can I use the Open as web page option with?

WebReady document viewing

 

 

Files not supported by the attachment viewer can be opened or saved. 

WARNING: After opening or saving file, remember to permanently delete the files from the computer and the local internet cache to make sure they are not left behind for someone else to read.

 

There is a third part solution, AttachView from Messageware Incorporated, which lets you view over 300 file types.  AttachView has extra security features letting Administrators turn the open, save and print options on or off depending on where you are connecting from.  For example, if you are on your laptop you can save, open and print attachments but if you at an airport kiosk you can only view the file.

 

Here is what the AttachView looks like:

 

Messageware AttachView

Why can I not open attachments, I can only save?

Your Administrator has likely disabled the Open option because of the security risks associated with this function.  When attachments are opened a copy is saved in the local computer, accessible to anyone who accesses the computer, even after logging off OWA.

 

OWA 2007 offers document viewing, called WebReady Document Viewing, which is a safe way to read a document without downloading it onto the computer.  The attachment us turned into a web page and displayed in the viewer.  You can view 4 document types: Microsoft Word, Excel, PowerPoint, and Adobe PDF.

 

There is a third-party called Messageware that extends attachment viewing to over 380 file types.   

How can I attach a file to my email?

To attach a file to a new message press the attachment icon shown below.

Attachment button in new message 

This will open a small window which lets you Browse the file system to find your file.

 Attach file interface

 

When you have found the file, click on it once and the path will be visible on the brows line.  To attach the file to your message, press the Attach button.

Press attach button

 

The file will now be visible in the new message.
