Follow up : what happens is that what I do in Mailmate no longer seems
to be reflected on the server (as far as I understand) : if I delete or
move a message in mailmate, it is not deleted nor moved when I open
another mail client (Outlook on the Mac, or Preside on my iphone). How
is that possible, and how can it be corrected?

In fact I experienced the same problem each time I relaunch Mailmate, or
restart the computer, which sounds weird I agree. In fact what possibly
happens is that each time I restart, a new mailbox send me an error
message (I did not follow carefully which mailbox sends me an error
message), and that will last until all mailboxes are synced again.
Hopefully once re-synced, they will remain so.

My server is indeed Exchange-based, but there is nothing I can do about
it. I finally did not reinstall Mailmate, and I am just waiting for
every mailbox to re-sync. Since I have more than 400 (exported from a
previous email client), it takes forever. It seems I have to open a
mailbox to force it to sync; Would there be a way to re-sync all my
mailboxes with a single instruction?
