"Message not saved" error
I just replied to an email, and now Geary has the message "Message not saved. This message was sent, but has not be saved to your account.". This is a yellow message on top of the message I sent in the Outbox. I'm not sure how I can force a refresh or cause this message to save to the server.
Additionally, I have gotten a reply to that message since, and Geary keeps showing the unread message notification, but the message itself isn't showing in the inbox. If I go to web mail or mail on my phone, it's there (still marked unread because I haven't read or opened it anywhere yet). It's just not showing up in Geary.
Even is I quit Geary by going to Geary (upper-left, next to Activities) -> Quit, then reopen it, I get the same behavior.
Is this some sort of networking/connection issue? I have no idea how to check, nor how to fix it.
