Hi,
I understand that in your scenario the users face the Outlook performance issue because of the large number of temp files.
Actually I can reproduce this issue on my side, that these temp files are occupied by Outlook unless we exit Outlook which will soon release the temp files, this is a by-design behavior in Outlook so I have to admit there is no easy way to avoid it.
The only workaround I know is what you have mentioned to restart Outlook, then the temp files will be cleared and the issue should be gone - It may be a bit troublesome for users in your scenario though.

The outlook's performance problem is because of the large size (150mb) of the one temporary file in the folder "%localappdata%\Temporary Internet Files\Content.Word"
