Endless Loop When asked to Login for Office 2016 on Mac

hi reuben,

according to the symptoms, it is most likely due to the remaining cookies and caches on the browser. could you first try the following?

1. try clearing the cookies and cache of safari.
1) click safari in the upper left hand side of your screen. in the menu that appears, click preferences.
2) in the window that appears, click the privacy tab. click the button remove all website data....
3) click remove now in the pop up window that appears.
2. try completely uninstalling your current installation and then reinstall according to this article: troubleshoot office 2016 for mac issues by completely uninstalling before you reinstall

if the issue still exists, could you provide related screenshots for our reference?

to upload screenshots, you can click use rich formatting at the bottom and then click the icon of insert media.
 

thanks,

i tried the steps you requested and it's still not working. the loop starts when i get to this screen and i can go any futher. any other suggestions?

Hi Reuben,

I'd like to confirm the following information：
1. What if you login to Office 365 via browser? Also try different browsers to check the result.
2. Regarding “my account is fine at my college”, can you also login from the Office for Mac client successfully?
3. Considering you have re-installed the Office client, if convenient, could you try to login with your account on another Mac or other Office versions to see whether the issue still happens?
4. To further investigate the issue, could you let us know whether the other users of your organization have the same issue?

If you have any updates, please let us know.

Regards,
Gene

I am able to login  in my browser(currently Chrome). I have installed the client on another mac at my school; however, I still have 3 licenses so that should be fine. I think this answers number 3 as well. I work as a technician for my school's HelpDesk, and I haven't heard any one else with this issue. I also have my personal OneDrive installed as well. Would that affect my installation?

Hi Reuben,

Installing OneDrive won't affect your installation.

Based on the updates, could you try clearing keychain to see if there is any improvement?
Here is an article for your reference:
Resetting your keychain in Mac OS X

Moreover, I'd like to confirm whether the issue happens when you login with your account in other browsers or different Office clients on other Macs. In addition, does the issue only occur in Word 2016 for Mac or all Office clients when you login?

Please let us know the updates.
