One user on the network found she was not receiving emails yesterday. I was told Internal email were getting through, but have not seen any since I've been investigating it.
I have checked the mailbox size and it seems below the limit which I have expanded just in case.
I have tried OWA from two other workstations and they show the same result as when on the users workstation.
If I search in Tools for emails, the report show many emails that haven't been transmitted to the users mailbox and the log show multiple attempts to send the email.
Can anyone suggest what is happening and how it can be resolved?
