outlook 365 ask for password randomly

Hi

For some users, a message pops up about entering a password randomly. Can be several times a day and another day not at all.

Even if they do not enter a password, it is enough for them to close the outlook and reopen it and it will work or if they enter a password (and even twice in a row) and the outlook will continue to work.

I've already seen questions on the subject here and tried to enter these values ​​in the registry editor and also delete from the Windows Credential any value .

Tried this also :

[HKEY_CURRENT_USER\Software\Microsoft\Exchange]

"AlwaysUseMSOAuthForAutoDiscover"=dword:00000001

[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity]

"EnableADAL"=dword:00000001

[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity]

"Version"=dword:00000001

[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity]

"DisableADALatopWAMOverride"=dword:00000001

This is the pop-up windows 

Please Help !!! 🙂
