My mail folders are there but all mail messages have disappeared and no new mail comes in. My accounts are online but nothing? Mail messages are there in Webmail and on phone. But nothing on my lap today. What happened?
Apple Mail (mountain lion) folders (that I set up, not the system folders) are there but all messages therein have disappeared and nothing shows in Inbox, Sent, Trash, etc. (system folders). Everything was there yesterday morning, last night started having trouble receiving mail on lap. But I could get it on Webmail and on iPhone. What happened to laptop Apple mail?
MacBook Pro (13-inch Mid 2012), OS X Mountain Lion (10.8.5)
