my emails keep dissappearing
When I click on the email icon on my desktop sometimes they appear and then just disappear what can I do to get them back and keep them?
iMac (21.5-inch, Late 2012), OS X Yosemite (10.10.5)
Try rebuilding the mailbox.
If that doesn't work, try re-indexing the mailboxes. This can take awhile if you have a lot of mail.
Reindex messages For El Capitan, try looking in V3. Sierra use V4. High Sierra use V5.
