I use Thunderbird to download my e-mail and have it set so when I message is downloaded, it is deleted. But that no longer happens.
When I tried to delete e-mail online, I got this error message:
An error occurred! Server Error: UID MOVE: IMAP session state is inconsistent, please relogin.
In less than one day, I'm at 20% of my quota. Before long, I will no longer be able to get e-mail and that's how I get notices of events and send out notices of events.
