Outlook for Mac sync issues
I've been having a strange, sporadic issue for the past several months. I'm using macOS Catalina and Outlook 16.35. Outlook sends and receives new mail just fine. But read/unread state, and moves/deletes don't get synced back to O365. For example I could be working on my MacBook for several hours. During that time I'm sending, receiving, moving, and deleting email with no apparent issues. New mail is coming in and mail that I'm composing is sending, and Outlook isn't notifying me of any sync errors. But then later I'll check email from another device or from my phone, and all of the mail that I've already cleared out of my inbox on my MacBook is still appearing as unread and sitting in my Inbox on every other device. Restarting Outlook on my MacBook doesn't fix it, but usually if I reboot my MacBook entirely and then restart Outlook on it, Outlook will finally sync everything. Any idea what could be the issue here? Is there a local cache I can flush?
