Outlook 365 w/ Windows 10 Pro crashes; repair and reinstall don't fix

(Cross-posted at Windows 10 Forums. Hope that's OK.)

Outlook 365 became unstable a few days ago and now is completely whacked. Our 365 subscription is in my name, but I share it with my wife and Outlook 365 usually runs on her Dell machine under her Microsoft account.

1. When run under her account, it either crashes right after opening, asking me to send the error report, or tells me "There was a problem checking this device's license status, please sign in ..." and then crashes, or tells me I'm missing a dll file (the file name changes from instance to instance, I think) and then crashes, or some combination of the above. But it always crashes.

2. When I try to open it under my Microsoft account on her Dell, I get a different error message, and then it crashes. It tells me there's a problem and Microsoft will tell me when there's a fix. (I'm paraphrasing.)

2. I tried "Change" and ran the "Quick Fix", but it didn't help. Then I ran "Online Repair"; it said it was installing the 365 suite but hung up and never completed. I tried this several times.

3. Then I uninstalled 365 and reinstalled it. The uninstall and install went smoothly. But even this didn't fix the problem.

The other Office 365 programs are running fine and there are no apparent problems anywhere else.

The last update on the machine is "Update for Windows 10 Version 1607 for x64-based Systems (KB3150513)" on March 16. The OS is Win 10 Pro 64 bit.

Any help would be enormously appreciated.

Well, I accidentally fixed it. I bumbled my way through a bunch of stuff and ended up accidentally deleting my wife's Profile. When I recreated it and re-linked Outlook 365 to her Gmail account, it worked fine.

Before I lucked out by forcing the need for a new profile, I had tried starting Outlook in Safe Mode. That didn't fix it. Then I repaired the pst files she used. That didn't fix it. I mention all this because these steps and more are suggested in  

https://support.office.com/en-us/article/Outlook-not-responding-stuck-at-Processing-stopped-working-freezes-or-hangs-5C313D04-64AF-4441-82D2-44E5A43EEE5A?ui=en-US&rs=en-US&ad=US

None of the suggested steps worked except the last one, Step 6 "Create a new user profile".

I mention all this to suggest the first thing a person with a similar problem should do is create a new profile.

Did this solve your problem?

Sorry this didn't help.
