I am a long time Outlook user (my work uses Exchange), but I am giving the more native apps a shot, including Mac Mail to access the Exchange server. It seems to usually work well, but I am sporadically getting this message:
The operation couldn’t be completed. (MCMailErrorDomain error 1030.)
The thing is - nothing SEEMS like it has gone wrong at the time I get the error message. When I clear the message, things seem to be working ok. I haven’t noticed any message fail to receive or send, or delete, or move to a folder. (Of course I could be missing it).
How do I troubleshoot this? Is it possible there is just a momentary drop in the connection with my Exchange server and this message flashes up on the screen. I am nervous trusting the Mac Mail client when I get these messages (as I don’t get anything like that with Outlook - other than being occasionally notified that Outlook has lost connection).
Any help or guidance would be greatly appreciated!!
