Enable modern authentication for Office 2013

MFA is becoming the standard with Office 365. A client of mine was experimenting with it and told me that everything seemed to work just fine except Outlook in their Citrix environment (Outlook 2013).

I immediately remembered that in order to enable modern authentication for any Windows device that have Office 2013 installed, you need to set a specific registry key. Unfortunately this is a per user or user specific setting. With this being the case, it won't work for my client.

However, if you have one or a couple devices running Office 2013 you can create a .reg file with the following and import it. Once this is done, you can use Modern Authentication with Office 2013 + Office 365.

Windows Registry Editor Version 5.00  

\[HKEY\_CURRENT\_USER\\Software\\Microsoft\\Office\\15.0\\Common\\Identity\]  
"Version"=dword:00000001  

"EnableADAL"=dword:00000001
