Outlook 2016 (Office 365) Stuck on Online Account login screen

My company has a hybrid configuration with Office 365 Online. My Outlook version is 2016, everytime i open  Outlook I get the Outlook loading profile window, a white screen then appears behind that which is all white but in Sandboxie the window shows [#] Accounts [#] I set there for 10 -15 minutes and nothing happens.

 

The white window with the black bar just sits there and it will not get pass this. Luckily i can use the web-based version but this did work a few versions back.

 

 

Currently on 5.31.4 (64 bit)

 

Any help would be greatly appreciated,

 

 

Thank you
