Do retirees still get to keep their accounts?

Retirees can request that their email account be retained prior to leaving the University.

Why am I getting prompted to sign into my email on my mobile phone everyday?

Office 365 applications respect our Multi-factor Authentication (MFA) service, which we enabled in 2019 to increase the security on your account. Multi-Factor Authentication is in place to prompt for your password once every seven days if you check the box on the sign-in page. Now that your mailbox has been migrated to Exchange Online, the MFA policy is in effect. We have a mobile device management policy that will allow you to bypass MFA on your mobile device so that you will no longer be prompted every seven days. Learn more about Exchange Online Mobile Device Management. 

What size attachments can I send with Exchange email?

How will I know another user's email address?

Why am I getting the error: “Outlook is trying to retrieve data from the Microsoft Exchange server outlook.office365.com?”

Users should run in cached mode for optimal performance. If they choose not to run in cached mode, they may run into slow performance when deleting or moving large amounts of email. They may receive a message saying that Outlook is not responding or “Outlook is trying to retrieve data from the Microsoft Exchange server outlook.office365.com.”

How to enable cached mode.

Why is the system slow when I delete or move large amounts of mail?

If you are experiencing slowness or error messages when deleting or moving large amounts of email, it is probably because you are not running in cached mode. For the best performance, we recommend you run in cached mode.

Why are my Inbox rules not working?

During the mailbox migration, it is possible that some of the rules that you created in your Outlook client or OWA may not transfer over correctly or at all, requiring them to be recreated.

Here are some steps to fix a rule that is no longer working:

Outlook Client
On the Home tab, go to Rules > Manage Rules & Alerts
Click on the rule that is not working and click Change Rule > Edit Rule Settings
If the rule looks fine, click "Finish" and then "OK"
If the rule still does not run, you may need to delete and recreate the rule


Outlook Web App
Click on the Settings (gear), and click on “View all Outlook settings” on the bottom of settings
On the left, click Mail > Rules and click on the pencil to edit rules
If the rule looks fine, click "Save"
If the rule still does not run, you may need to delete and recreate the rule

What is the Focused Inbox and how do I turn it off?

When your mailbox is migrated, you may notice something that says Focused Inbox. Focused Inbox separates your Inbox into two tabs - Focused and Other. Your email messages deemed most important are on the Focused tab while the rest remain easily accessible - but out of the way - on the Other tab.
