I'm setting up TB for the first time with multiple email and calendar accounts. Some are gmail / google, and others o365. The primary TB account's calendar doesn't seem to be syncing fully. It's an o365. account. But the email is working. I added an event on my Outlook for Android on my phone. Its appearing in OWA, and in New Outlook on my computer (so it did sync from mobile Android device to server, and from server to my New Outlook on the Windows desktop). But its not appearing in TB. Not sure what to check or what the issue might be. Also, I'd love to replace Outlook Android on my mobile with what I think is K-9. But can't get the same account referenced here to connect to the outbound server. Welcome any help, and appreciate you all doing this collaborative work.
