I have a user who is running MacOS Sierra and Office 2016 for Mac. Last week, his mail synchronization in Outlook stopped working and he began getting prompts to enter his password.
I have verified he can use the same password to log in to the portal. (He had a personal outlook.com account which continues to work fine) We have tried removing and re-adding the account and even performed a reinstall of Office after deleting all com.microsoft. items from his user accounts /Library/Containers folder on the Mac.
Launch Outlook; 4. Outlook keeps asking for activation. May be connecting to my Office 365 account was not to be the best idea. Outlook kept requesting for activation. Online I didn’t manage to find a satisfactory solution. I decided to uninstall again, but this time Outlook only.
Office will reinstall and run correctly but when we try to re-add his email account, the Office 365 authentication screen keeps popping back up, even after entering correct username and password information. (We even get the expected Autodiscover prompts) This occurs whether we select automatic configuration or try to manually specify the server configuration. Hi Ken, Based on your description, I understand the affected account is an Office 365 account, right? If so, I suggest you try the following steps and check if there is any improvement: 1. Make sure you quit Outlook and other Office apps. Go to KeyChain Access; (Applications/Utilities/Keychain Access) 2.

Search 'Exchange' under Login All Items and delete everything; 3. Search 'Office' and delete everything; 4. Search 'ADAL' and delete everything; 5. Launch Outlook; 6. You will get the activation to prompt.
If the account is already added, you will see the password prompt for the app and ADAL again. Please do 2-Factor Authentication if asked to and you should be able to login. However, if the issue persists or anything is misunderstood, I’d like to collect the following information for further troubleshooting: 1. How did he configure his account in Outlook for Mac?
Via Exchange or IMAP/POP? Some relevant screenshots about ‘the Office 365 authentication screen keeps popping back up’. What's the detailed version of you Outlook for Mac client? (in Outlook About Outlook) Thanks, Sam.
