One of my team members approached me today asking about an issue they're having with their Mac Mail Client and Gmail. I am a Linux user and do not have much experience with Mac, but thought I would reach out to this community on their behalf.

  • User aggregating 3 email addresses into Mac Mail (Gmail Personal, Gmail Professional, Hotmail)
  • All email providers set up properly as IMAP (POP on phone)
  • User experiences duplicates in both Sent folder
  • User's Drafts folders has incomplete information (some emails are missing)
  • Mail Server information appears to be correct


I am thinking that this might be an issue with IMAP vs. POP, but I figure that the Sent folder would be suffering from similar issues. What

  • How are the mails compared to the online gmail client? Does that look correct compared to Apple Mail? – Hoshts Oct 28 '15 at 23:28
  • The emails are exact duplicates - no changes in text or HTML form. What is your reason for asking? Do you think it might be a forwarding issue? – jonplaca Oct 29 '15 at 16:36
  • I meant the mailboxes and how the mails add up there compared to the Apple Mail. Are there duplicates in the web interface as well? Same mails missing? – Hoshts Oct 29 '15 at 17:04
  • @Hoshts Thank you for the clarification - The duplicates are only showing up in Apple Mail. – jonplaca Nov 2 '15 at 16:18
  • Ok. So the online gmail accounts look correct then. That is good and sounds more like there is a problem with Apple Mail and not syncing. Have you tried to rebuild the mail database in the application? – Hoshts Nov 2 '15 at 16:26
