My event log is littered with the following error.
An error occurred while delivering mail to 'email@example.com' on the SMTP server 'localhost'. The error code was 0x800ccc6c. Verify that the mailbox exists and that the Exchange receive connectors are configured properly.
Mail is not being downloaded at all. I have read different reasons for this. On the basis of articles I have found, I have expanded the potential mail store file size to 60 GBs. I have also checked that the firewall isn't the cause. My connectors are all working the same as they have always done. The pop3 connector has always worked perfectly well. There have been no updates done to the server.
The pop3 log is not even possible to open as it has grown to such a huge size (GB). I have tried renaming the extension to .zip and still no joy.
Any advice would be greatly appreciated!
