Evolution mail: Deleted Items folder behavior

Hi all -

Thanks for your time and trouble making Evolution available. I'm having two
issues that may be related:
1. I can't seem to expunge items in the Deleted Items folder (e.g. right
clicking on the folder doesn't show an 'Expunge' option)
2. Expunge (Folder > Expunge) doesn't seem to work in any case.

I'm using Evolution to interact with an Office 365 account, so I'm using
the evolution-ews package as well.

) pkg info -q | grep evolution
evolution-3.42.1
evolution-data-server-3.42.1
evolution-ews-3.42.1

I'm wondering if I'm just missing an additional library (or configuration
step), as I also use Evolution on a Void Linux install. It's running a
slightly older version (same packages but v3.40.2) but doesn't exhibit the
same problem.

Does anyone have any advice for what can I do to try fixing this? Thanks in
advance for your help.
Best,
Bridger
