Mail error on Macbook Pro "The IMAP command “UID COPY” (to **********) failed for the mailbox “INBOX” with server error: Store partition is full."
I am using a Macbook Pro (iOS 10.10.5) and since yesterday I have been receiving the following error when I try to delete or move mail in the Mail app "The IMAP command “UID COPY” (to **********) failed for the mailbox “INBOX” with server error: Store partition is full."
Testing mail indicates that I am no longer receiving any mail for any of my @me.com account on either my iPhone, or iCloud webmail either.
I have checked my iCloud space and I still have 3GB free.
Once I try moving messages to other folders I get the above message and the emails appear to disappear. In addition, no emails I am sending are appearing in the sent mailbox.
