Microsoft says “This is an occasional timing error caused by not locking the mailbox during use. This can be safely ignored unless these errors occur frequently.” but this is not occasional for me, I’ve a lot of warning. In addition, on Ipad/Iphone there are many mail with wrong receiving date (in Imap are correct)
