    Ok so now I tried the same registry settings on a computer with Office 2016 and IT WORKS!

    Oh course I had to change for version 16 in the registry.


    HKEY_CURRENT_USER\Software\Microsoft\Exchange\AlwaysUseMSOAuthForAutoDiscover REG_DWORD 1
    HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity\EnableADAL REG_DWORD 1
    HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity\Version REG_DWORD 1

Jeesoon Hey there , I want to share with you the most stupid way ever to fix Outlook 365 (latest preview build of MAfB v2303) asking for password....

 

Today, all of a sudden, the prompt (Windows Security) popped out asking for password. I ticked remember, entered the password, clicked OK. It asked again for password... I entered again, then the Autodiscover (certificate window) appeared i clicked Yes... Spent the next 4h trying to fix, using regedit, all the possible tips & tricks to overcome the issue. Also created new Win user profile, in which it worked flawlessly... switch back to main user account, tried the store app Mail, it worked, no issues there... 

And as i was getting ready to give up... I remembered there is an option "Try the new Outlook" (top right corner under X to close Outlook 365 for Desktop)... I did, it downloaded new ver. asked me to Switch, so i clicked on it as well... Waited for it to import settings and preferences... and bam! no password prompt. 

Microsoft, seriously what the hell is going on? If anyone knows what does this have to do with anything please explain...

    Antrophin3 Also in addition to that possible fix of trying the new outlook design... 
    I have also applied the 3 .reg edits, switched back to standard Outlook, and voila... works again. Thanks so much for these @OP. 

     

    Here is the code to make the .reg file (in Notepad). Just copy and paste it to new Notepad document, and save it as "LoginFix.reg" or however you wish... 

    Windows Registry Editor Version 5.00

[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
