Outlook blank authentication window When connected to office 365

After migrating from on-perm to Office 365 on terminal server I get this blank authentication window. the fix I found is to add in the registery this key :

HKCU\SOFTWARE\Microsoft\Office\15.0\Common\Identity\EnableADAL
REG_DWORD
0

or

Windows Registry Editor Version 5.00
 [HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity]
 "EnableADAL"=dword:00000000

After adding this line, Outlook got connected with no issue
