I saw in the MS knowledgebase where there was a certain update that was part of the issue but that was quite some time ago and MS has since issued patches to fix it in relation to that update. I've gone to the Office 365 Admin console and everything looks okay with my account, if it wasn't it would most likely give me issues on the service as well but I checked it any way just to be sure. I put in my user name and 3 maybe 4 other pop-ups briefly appear but it does not log me in.Īlso under Email & app accounts I go to 'manage' the account in question it takes me to a web portal page with various options and I tried the 'Sign out of all devices & apps', then waited a bit and tried again and still no worky. In 'settings' under Shared experiences it tells me I have a problem and has a 'Fix now' button, I click that and an Office 365 login prompt comes up. That was the first thing I tried this time but no go. Last time about 4 or 5 months ago what finally worked was clearing out all my temp files and rebooting. I have done a number of searches and found related issues but none of those fixes have worked. I have a service spare that I tested with and I am able to login to Office 365 without any issue.

I can open any Office 2016 app installed on my computer but I am unable to link/login to my Office 365 account on my primary computer.

Had this issue once before and was able to fix it but last time's fix isn't this time's fix.
