Hi, for some reason Outlook has started prompting users for a password and automatically populating the username box with email@example.com
No matter what we do it will not accept the password, I've changed it to username, domain\username, email address but nothing works and the password box comes back each time. The strange thing is emails still continue to send and receive when you cancel the login box.
All the PC's are running the most up to date versions of either Office 2013 or 2016 and Exchange 2010 is also up to date.
Sure it's an authentication setting somewhere in Exchange but I'm struggling to find it.
Many thanks for your help
