As you've probably discovered, every version of EV is not tested with every version of Exchange.
The very best is to:
a/ Read the forums
b/ Test it in a lab.
We are faced with an issue with Evault 220.127.116.115 with Outlook 365 (ver1808) on Windows 10 desktop.
In short after a simple email search, clicking 1,2, 3 items recovered and trying to open it, Outlook crashes without error messages. It's systematic.
I didn't see similar issue and hotfix.
Any idea ?
