Office 365, Email, Exchange account, Outlook Desktop and Outlook on the Web FAQ

This page contains information about Office 365 and Exchange online accounts. Including common questions.

Eligibility for Exchange Accounts

Some campus individuals are automatically eligible for Exchange accounts; others can have accounts created for them by request.

Whether or not you are automatically eligible for an Exchange account depends on your identity type in the campus identity management directory. If you want to see whether your identity type qualifies for an Exchange account, log in to the Electronic Directory Editor and look at the contents of your uiucEduType field.

New University accounts that are eligible are automatically provided with Microsoft 365 mailboxes and licensing during the account setup process. Provisioning takes time, but users are usually able to sign in to Microsoft services 2 hours after finishing NetID Claim or UI New Hire.

The Microsoft 365 services are attached to an account during an automated process which is started at the end of the Claim or New Hire process. This means that users MIGHT not be able to sign in to email until they have waited 2 hours after NetID Claim / UI New Hire.

Accounts that existed before the University transitioned to Microsoft services, such as those of returning former students, do not use the NetID Claim process, and thus may not have a mailbox automatically provisioned. Your mailbox is provisioned after you register for classes (usually 1 to 2 days). Please see this article for undergraduate to graduate transition (https://answers.illinois.edu/illinois/62783

If it seems like your University account has not been provided with email even after waiting 48 hours, or if you are newly hired or enrolled and having any other trouble with your University email, contact the Technology Services Help Desk at consult@illinois.edu or 217-244-7000.

Automatically eligible for Exchange accounts

People in the following groups (determined by the following types) are automatically eligible for Exchange accounts:

  • Urbana faculty, staff and academic hourly employees (required type: staff)

  • Urbana Foundation and Alumni Association staff (required type: allied)
  • UIC Medicine and Nursing (required types: must have both extramural and allied-medicine or allied-nursing)

If you are a member of one of these groups and do not already have an Exchange mailbox, your Exchange online mailbox will be automatically provisioned.

Account created by request

People in the following areas (determined by the following types) can have Exchange accounts created for them by request of the proxy or sponsoring department:

  • Urbana guest users (required type: special)
  • University High School students (required type: unihigh)
  • Visiting Scholars
  • People on approved leave of absence
  • Other affiliates that work in some capacity with the University

Account policies

Your login and password serve as your identity within the campus computing system and control access to sensitive personal information. Because of the potential for harm, it's very important that you never let anyone else use your account, login, or password - not even your parents, siblings, friends, or roommates. Any sharing is against campus computing policy and could result in losing your account privileges. A complete guide to the University's computing policies is located at: http://www.cio.illinois.edu/policies.html

Leaving the University

Faculty/Staff should refer to Identity Management, Leaving Campus for Faculty and Staff.

Students should refer to Identity Management, Leaving Campus for Graduating Students

Legitimate email ending up in Junk Mail

Legitimate email from university or other trusted sources are ending up in my Outlook Junk Mail folder
Microsoft has changed the way Junk Mail is filtered within the Outlook Client.

This filtering controlled by Exchange Online Protection (EOP) will utilize it's own mailflow delivery agent to determine if any given email is Spam and will move email to the Junk folder. This means it no longer reads the user setting in Outlook's Junk Email Options for choosing the level of junk email protection: No Automatic Filtering/Low/High/Safe Lists Only. This EOP will continue to honor the user safe sender/block sender preferences set in Outlook just as the junk email rule does today.

If you do have legitimate email being filtered as junk there are steps you can take to prevent this from happening in the future:

  1. Add the Sender's address to your safe sender list in Outlook or Outlook on the Web.
  2. In Outlook on the Web, Microsoft has a process for Reporting to them email that should not be junk:
    1. In Outlook on the Web, go to the Junk Email folder and find the message that was incorrectly marked as junk.
    2. Right-click the message, and then click Mark as not junk.
    3. In the Report as not junk dialog, click Report.

    Your report automatically goes to the Microsoft Spam Analysis Team at not_junk@office365.microsoft.com.
    Microsoft will use your report to help improve their spam filters.

You receive an error message about insufficient space for rules

I am receiving an error message that there is insufficient space on the Exchange server for additional rules.
The default quota size for rules on Microsoft Exchange is around 64 kb. The Exchange group can up this quota on a per user basis.
The rule space allotted to a mailbox is not unlimited as there is a firm maximum as defined by Microsoft as 256 kb. 

Please send Requests for rule space extensions to exchange@illinois.edu
