Document in "Read-only" mode all the time

Hello,

have you tried different computer? I know it's not a solution but form my experience:

Computer A

Windows 10, version 1803, build 17134.376, Office 365 - 16.0.10827.20181 64bit (clean installation)

Computer B

Windows 10, version 1809, build 17763.55, Office 365 - 16.0.10827.20181 64bit

On both computers I logged in with the same account with nice result:

Computer A - can create document, edit it, save it, but it's read only when reopened.

Computer B - works normally as expected.

Just two people out of twenty have this problem.

I tried everything from your list + manual reinstallation from 32bit to 64bit Office version + Online repair.

So I does not seems to be a library problem from my point of view. 

I have problem only with recent documents in the library but the newly created have this kind of issue. May be MS fixed that already…..

I also found similar problem in 2016 forum with note "Our engineers are working on the fix" and saving another document copy as a workaround.

Nice :), any idea?

Thank you.
