I have a user that is having trouble with people scheduling appointments. I can set up a calendar invite and invite her to a meeting and it works ok, then if I update the meeting, send a comment or cancel the meeting I get a bounce back. Delivery has failed to these recipients or groups:
xxx xxx (
The recipient's mailbox is full and can't accept messages now. Please try resending this message later, or contact the recipient directly.

However I can send the user regular emails, she does not have the largest mailbox in the company and everything else is fine. She is using the default mail quotas. Everything else in Exchange looks like it is the right setting, however if I try to move her mailbox to another database, I get the error in the attachment; Mailbox Dumpster size 100.1GB....and so on.
I assume they are related but have no idea why either issue is happening. All input welcome
