New Outlook - GMail account keeps asking for re-authorization

I am using the new Outlook since a few months now, with both a personal Outlook (Microsoft 365) email account, and a GMail account. Both were working fine until a few days ago. Suddenly (probably after the latest update of the app) Outlook has started constantly "disconnecting" from the GMail account. Now, multiple times per day, I am locked out of my GMail account and I have to go through the authorization process with Google all over again: Outlook is asking 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. Sometimes, it will work for a few hours before I get disconnected again. Other times, I am stuck in a loop where I authorize Outlook, get redirected to the app, get locked out again, redirected back to GMail authentification, back to Outlook... and so forth.

It goes without saying that this is extremely annoying to the point of being unusable. Are you aware of this issue and is there a planning to fix it?

    Hi @Mathieu Ackermann ,

    Have you enabled two-step verification for your Gmail account? We recommend turning on two-factor authentication and using an app password. For step-by-step instructions to set this up see: Turn on two-factor authentication and get an app password,

    If it still doesn't work, I suggest you remove your Gmail account and re-add it again.

    Half year later, same issue for me. I thought I would give new Outlook a try after all - at least for my private stuff, but this makes it completely unusable for Gmail integration.

    Kind of sad. Once authentication is eine, Integration of Gmail in Outlook is really nice and functional.

    I guess MS has no real Intention of solving this, if the issue still exists after 6 month ...
