Using classic Outlook for Windows in business environments
I used to have this problem all the time but it's been working fine lately.
I have removed and reconnected the Gmail account from outlook for windows and from outlook for Android. I think that helped.
We've tried this same thing with a few of our users and it seemed to work for a day or two, then things would revert back to how they were. The fact that Microsoft hasn't even officially acknowledged that there's an issue here is annoying, and I've been using a different client entirely.
