Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi
after the first attempt by Microsoft, which seemed to have worked for me, after a couple of days, the issue returned.
This time, they asked me to try something else which is to force some kind of different login screen for the O365 account in Office 2016.
This is what I did (and since a couple of weeks, I have had no issues):
Go to the registry editor (Win+R; regedit)
go to HKEY_CURRENT_USER -> Software -> Microsoft ->Office -> 16.0 ->Common -> Identity
Inside "Identity", create a new REG_DWORD value called "EnableADAL" and leave the value at 0
Restart the PC and try again to login from Office 2016. In my case, the logon screen was now different and it worked perfectly.
Hope this helps you
Thanks,
Bruno Sales
