Message being deleted locally

[Johan P. <joh...@er...>]

Hi,

I have a setup at work where the company is using MS Exchange +
OAUTH2. I use DavMail to deal with OAUTH2 and then mbsync to connect to
DavMail. As MUA I use notmuch.

This was working OK for a while I think but then I started noticing
messages missing locally. Also I have seen messages being synced and
then later being deleted. This semms to have become worse and worse and
there are lots of messages missing.

I would very much like help in debugging this, I'm attaching my
mbsyncrc.

In my setup it is actually not necessary to sync upstream. It would be
OK to just sync everything from the server down to my local storage and
nothing back - if that would help. As it is now the only thing being
synced back is the Sent folder, but that's not necessary.

I'm on MacOs Sonoma 14.5. I installed mbsync via homebrew and it is
1.4.4.
