Outlook Password Prompt Issue | O365

Outlook Password Prompt Issue | Scenario

Have you migrated to Office 365, and Outlook 2016 keeps asking for password and credentials? Are the repeated Outlook password prompts driving you insane? Is your confidence in Office 365 being eroded by the random attack of the Outlook password prompt?

I recently completed an Exchange On-Premise migration to Office 365 for a customer. The migration was a cutover from Exchange to Office 365, with no hybrid connection. The migration went really well with a pilot migration, followed by the remaining mailbox migrations over a weekend.

The users were all using Outlook 2016 (Pro Plus) to access their Office 365 mailboxes.

However, over the next few weeks, users would complain about receiving Outlook prompts for credentials. Outlook would load up okay, but then disconnect at random times.

If the Office 365 credentials were entered (email address and password) – this would not clear the credential box. My customers had to resort to using Outlook Web Mail for their mailbox access, as at least that was reliable.

Outlook Password Prompt Issue | Symptoms

Do these symptoms sound familiar?

Sometimes, cancelling the Outlook password prompt box would make it go away.
Sometimes, re-starting Outlook 2016 would make the password prompt issue go away.
Sometimes, creating a new Outlook 2016 profile would make the password prompt issue go away.
Office 365 support did not really help in resolving the password prompt issue, suggesting that the Tenant health was fine.
You are feeling very frustrated and have lost confidence in Outlook 2016 and Office 365

However, one thing was consistent. The dreaded Outlook 2016 password prompt issue would return for the same user, or for a new user. There was no real pattern to the problem. This was making it hard to solve, with users plagued by this Outlook password prompt issue.
