[ms office - 2019] Outlook freeizing on first startup, after closing and reopening it is completly fine

[Tjclark12]

Our head of finance and HR has an issue with his outlook on startup, it freezes if you go to reply to an email first thing in the morning, it is however then fine after we restart the program. We have changed his cached exchange mode setting to only download email from the past 3 months, this is as low as he can go. I have also set up an auto archive on one of the shared mailboxes he has hoping this would resolve the issue, but it has not.

 

Any ideas or help would be appreciated
