Connecting through Microsoft Exchange.

[AlokBeheria]

Hi All, 

I am trying to connect Excel through my email account which was running fine, and all of the sudden it's stop working and giving out following error. Not sure why it's stopped working while I can connect using other email.

I would really appreciate if you could offer your suggestions here.

Regards

That means the token expired or was revoked by admins. In general that's question to admins.

You may try to clear all permissions on that data source an create them again. Perhaps sign-out before from you account in Excel and sign-in again, not sure.
