New Outlook - Gmail account keeps asking for re-authorisation

Kent 75 Reputation points

I've been using the new Outlook for a few months now, with a personal Outlook account (, and three Gmail accounts, two have custom domains (one corporate and one NFP) and one is All were working fine until a week ago. Suddenly Outlook started constantly "disconnecting" from one Gmail account. Now, every time I return to that account after viewing another account, I have to go through the authorisation process with Google all over again: Outlook asks me to connect to Google, I am redirected to a web page where I have to allow Microsoft services to access my Gmail account, then redirected back to Outlook. I've asked my company admin if they changed anything and they assured me they didn't.

It goes without saying that this is extremely annoying to the point of being unusable. Does anybody know how to fix it?

    Just updated to the New Outlook in Windows 10 and I am experiencing the same issues. I have 4 email accounts, 2 of them gmail, and they keep logging out every single time I close outlook or restart the computer. This was not an issue with the old outlook, which I still have installed and works fine. I tried re-adding accounts and this does not solve the problem. Please fix this soon.

    Guys I was able to get this working with gmail using IMAP....just look for "Advanced Settings" (sorry I have my outlook in spanish and I'm guessing)...normally that "Advanced Settings" button is available if you click on Cancel button on the popup screen you get when add the account (When ask you for a confirmation to import your contacts, is the second screen you get)
