Cave Man

So, starting with Big Sur 11.4, Mail.app on my computer doesn't find some emails when I search for them using the Search box. In addition, it seems to be consuming quite a bit of CPU time (100% to 120%). I just updated to 11.6 this morning and the problem persists. I've rebuilt my mailboxes but that did not seem to fix the problem.

Also, it stops downloading messages after an hour or so and I have to quit and restart it to download new messages. This is on an Exchange server. Any idea what might be occurring?
