Frequently Asked Questions


Can I get a brief overview of some of the features in Exchange 2010?

Please click here for a quick guide detailing the major changes that accompanied the upgrade to Exchange 2010.​​

What is the maximum message/attachment size allowed in DePaul's Exchange 2010 environment?

The maximum permitted message size, including all attachments, is 25MB.

How do I manage junk-mail filtering in Outlook?

DePaul employs a spam-filtering service from Google called Google Apps. In order to eliminate conflicts and confusion, Information Services has disabled user-configurable junk mail setting options in Outlook desktop client (2013 for Windows, or 2011 for Mac OS X) and from Outlook Web App. Users can only add users to the Safe Senders and Blocked Senders lists. These lists are synchronized between the Outlook desktop client and Outlook Web App. ​​

How do I block or unblock a sender in my DePaul e-mail account?

The easiest way to manage blocked senders is to use Outlook Web App. To block the sender of a message that you have received, simply right-click on the message and choose "Add Sender to Blocked Senders List," as depicted in the image below.

You can also manage your blocked senders list by visiting the Exchange Control Panel (which can also be accessed by clicking Options > See All Options in the top-right corner of the Outlook Web App). Choose the "Block or Allow" option on the left side of the page; you will then be able to add or remove e-mail addresses from your Blocked Senders list. Be sure to click the "Save" button in the bottom-right corner once you are done modifying the list.


Outlook 2013/2016 (Windows)

How do I assign delegate permissions? I use Outlook 2013 or 2016, and I am unable to create a separate Outlook profile for a resource account that I own as directed in the Resource Account Instructions guide.

When you are the owner of a resource account, the resource account will appear within your primary Outlook profile. You can assign delegate permissions from within your primary Outlook profile on a per-folder basis. Under your resource account's name in the left navigation bar, right-click on the folder for which you wish to delegate access (for example, Inbox) and choose Properties. On the Permissions tab, you can add the appropriate users and permissions for your delegates. If you have any issues performing delegation in Outlook 2013 or 2016, please contact the Technology Support Center for assistance.​​​

I received the following warning when using the Outlook desktop client. What should I do?

Auto Discover Error image
Autodiscover is a service that automatically configures and updates your Outlook profile. Please check the “Don’t ask me about this website again” checkbox and click “Allow.” This will ensure that the Autodiscover service will run properly without prompting you for a confirmation on a regular basis.​

When sending an e-mail to someone, why do I receive a warning from the Outlook client stating the following?

Email Address not valid warning

This warning commonly displays when the Autocomplete cache becomes corrupt. The Autocomplete feature suggests commonly used e-mail address based upon your past e-mail recipients. There are two ways to clear the Autocomplete cache:

In the Outlook desktop client, follow these steps:

  1. Click on the “File” menu
  2. Click on “Options”
  3. Find the “Mail” tab on the left hand side of the resulting window
  4. Scroll down to the “Send Messages” section
  5. Click on the "Empty Auto-Complete List" button
  6. Restart Outlook

Use the following steps to start Outlook with the Command Prompt:

  1. Click the Start menu icon on the bottom left hand corner of the Windows desktop, or press the Windows key on your keyboard
  2. Type “Command Prompt” in the “Search programs and files” textbox
  3. Under “Programs,” click on “Command Prompt”
  4. Type the following (including quotation marks), then press Enter:
    1. "C:\Program Files (x86)\Microsoft Office\Office14\OUTLOOK.exe" /ClearAutoCompleteCache

My Outlook desktop client prompts me for a password in the lower right hand corner of the Outlook window. The same behavior also occurs when I try to synchronize my Outlook client manually via the “Send/Receive” button. What should I do to correct this problem?

If you use the Aventail VPN client, it’s possible that it may have timed out overnight due to inactivity, which would cause this behavior to occur. Restarting the Aventail client should resolve the problem. However, if you continue to experience this behavior, please feel free to contact the Technology Support Center. ​

Archive & Retention

Will the AutoArchive feature still be available in Exchange 2010?

A: The Auto-Archive feature is not available in Exchange 2010. All messages in your mailbox now adhere to the following retention policy:

  • 18 months after their send/receive date, all e-mails will move from your mailbox to an online archive located on the University Exchange server. Other Outlook data (i.e. notes), will move to the same archive 18 months after their creation date.
    • The send/receive date indicates the time that you received a message (i.e. the time an e-mail enters your “Inbox”), or the time you sent a message (i.e. the time an e-mail enters your “Sent Items” folder).
  • Messages will be retained indefinitely; however, the online archive is limited to 50GB in size. You can see the current size of your archive in the bottom-left corner of the Outlook client when viewing any of the folders within your archive.

You will have access to your online archive from the Outlook Web App and from your Outlook desktop client.​

Can I import a .pst file into Outlook 2013?

Yes, it is possible to import a .pst file into Outlook 2013. Please follow these steps to do so:

  1. Click “File”
  2. Click “Open”
  3. Select “Outlook Data File”
  4. Navigate to the directory where your .pst file is located
  5. Select the .pst file by clicking on it
  6. Click “Ok”

Your .pst file will appear as an additional folder within your current profile. If you create a new Outlook profile, you will need to import your .pst file again to interact with it.​

Can I save a voicemail message?

Yes, you can save voicemail messages. Whenever you receive a voicemail message, a copy of that message will be sent to you via e-mail, which you can keep for as long as the University retention policy allows. Unless you delete the message from your Outlook desktop client, the Outlook Web App, or through the voicemail menu on your phone, the message will remain saved and available for the remainder of its retention period.

Can I move my voicemail messages to a different folder in the Outlook desktop client or in the Outlook Web App?

​As long as the e-mail has not been moved to your online archive, you can move the voicemail messages to another folder of your choosing. Up until the point where those messages are moved to your online archive, you will also have access to those messages from your phone’s voicemail menu.​

I put a voicemail message in my online archive. Why do I no longer have access to it through the voicemail menu on my phone?
