For the past 48 hours, I have been unable to delete emails from Mail's Inboxes.
The error message reads:
The message "email subject" could not be moved to the mailbox "Trash - email account"
"nnnnnn.emlx" couldn't be copied to "Messages" because an item with the same name already exists".
I have closed and reopened Mail and also rebooted the iMac, to no avail,
However, it appears to be intermittent as sometimes I can delete emails as normal, sometimes attempting to delete the same email a second time works and somethimes it doesn't.
As I can't detect a pattern, I am at a loss as to how to find the cause - any suggestions one and all?
Thanks in advance.
