With irritating regularity, Outlook will not actually sync my local inbox - even after the 'Synchronize Now' button is used multiple times.

In these scenarios, I can attempt to quit and restart outlook (I frequently need to force quit), but the inbox still won't actually sync. If I want to actually receive new messages, I need to fully reboot my machine for outlook to pick up new messages. Force-syncing doesn't resolve the issue, quitting / force-quitting and re-starting Outlook doesn't solve the issue, only rebooting the machine does.

I am running on an up-to-date version of Mojave, and I keep the Outlook app updated regularly. This issue has persisted for a while now
