Office 365 requires sign in everytime now - started last week

Our family has the 365 five-pack plan, and we all use the Office apps everyday. Last week my wife's Office apps started requiring sign ons every time she starts them - Word is where we noticed it first, but it happens on everything.

My Office apps do not do this.

We have tried:
The credential manager fix (deleting all passwords)
The delete "Identity" folder in the registry
Logging onto the online account
Reinstalling the entire Office suite
Changing to a local account on the computer
...pretty much any fix listed on the internet.

We have always used them not signed in for two years without issue. And mine still works without siging in.

I too am seeing this problem, for about the last 2 weeks. I do not wish to login to Microsoft. My PC has a local account, for all sorts of reasons I won't go into here. This will not change. I start a bunch of apps using a batch script, including opening a Word and an Excel document. But now Word and Excel documents don't appear until I deal with the stupid new signin message. No doubt this is Microsoft policy, forced upon us without asking. However, I am hopeful there is a way around it.

Interesting...something must've changed. Hopefully, someone can help us.

Well, not sure what you mean by bonkers. But I'll add this, eventhough it may cloud the issue a bit.

On my system, at the same time my wife noticed her problem, I realized Outlook had decided to sign my entire office suite into my work account and connect all my apps to my work's Onedrive. All of my personal notebooks were being sent to my organization. Now remember this is my own purchased copy of Office 365.

The only way to get it to stop was to remove my work's email account from Outlook. So now I have Outlook for all my personal accounts and that free Mail app for my work. Now my Office apps remain signed out — which is what I want.

Big pain.

Microsoft, in its wisdom to decide what's best for me, has screwed up a once perfectly working system and caused me to have to use lesser apps to circumvent their bad move.

Yes, the most recent. Version 1803 (OS Build 17134.228)

I don't think it has anything to do with your hardware, but you might want to complete your computer specs in case you need help for something else,

It's my experience that the gurus around here (where are they?) will look at your specs first . . .

Thanks, Wynona, but I've built all my own systems for the past 20 years and use them for fairly complex work. I'm sure it's not hardware related.

I've found a workaround and I'll just stick to it for now. Appreciate it.
