Apple - Apple Mail.app hides Archive folder - how to get it to show
I just had this problem on OS 10.10 (Yosemite). Here's how I solved it:
- Select the inbox.
- Right-click "Account Info"
- Select "Messages on Server" tab.
- Wait until the size of all of your mailboxes is calculated.
- Select the Archive mailbox and click "Show Messages" button.
The archive now appears in the mailboxes bar.
