Exchange Online - Can't Setup Outlook App for iOS, "your email server is not configured properly"

Issue/Question

• I am trying to setup the Outlook app on my iPhone but I get the message "our app log shows that your email server is not configured properly to work with the Outlook mobile app. Please copy the link https://techcommunity.microsoft.com/t5/outlook/deprecating-eas-support-for-outlook-for-ios-amp-android/m-p/63799 and send it to your IT administrator to fix the issue. Let them know that you are unable to log in because the email server is set up incorrectly."

Environment

• Oregon State University
• Exchange Email
• Employee, Student Employee

Cause/Explanation

This issue can occur if your Exchange mailbox was recently setup but has not yet been migrated from Exchange on-prem to Exchange Online. Newly created mailboxes are usually migrated within a couple of days.

Resolution

Contact the Service Desk or your department IT. We can confirm whether your mailbox has been setup successfully in Exchange Online. It is best to wait until the mailbox has been setup on Exchange Online before configuring mobile apps.

Until your mailbox is setup, you can access your email via a web browser at: https://exmail.oregonstate.edu/owa
