It seems to only be for one mailbox. The Mailbox will work fine, sending and receiving. But it takes forever to sync mail or even sync at all. It seems to sync 3-4 messages, disconnect, then sync 3-4 messages, then disconnect again. This mailbox isn’t super huge 10k messages or so. I have bigger mailboxes on my server. I do not notice any other mailboxes acting the same way and no other users reporting any issues. The server is up to date and is only using about 80% of memory and 5% CPU. Logs look normal. everything seems normal. Any ideas?
