We have a single Exchange 2010 server.
A month ago a user tried to email another user (Bob) from OWA and received this error message, "This message can't be delivered to because their mailbox is full." We don't have any mailbox quota limits. I ran this commandGet-MailboxStatistics bsmith | fl StorageLimitStatus in EMS and the result wasBelowLimit. After a day it seemed to have fixed itself.
Today a user tried to email Bob from Outlook 2007 and received a similar message (I don't have the exact wording).
I ran the above command again and received the same result - BelowLimit.
What could be causing this problem?
