Apple mail app collapse folders

The frustration of collapsed folders in Apple Mail!

Don't worry, I'm here to help you troubleshoot and potentially fix the issue. Here are some steps to try:

  1. Check the folder settings: Make sure that the folders you're experiencing issues with are not set to "Collapse" or "Show only unread messages". To do this:
    • Open Apple Mail and select the folder that's collapsed.
    • Click on "View" in the top menu bar.
    • Select "Folder Settings" from the dropdown menu.
    • In the "Folder Settings" window, ensure that "Collapse" or "Show only unread messages" is not selected.
  2. Try refreshing the folder: Sometimes, a simple refresh can resolve the issue:
    • Select the collapsed folder.
    • Press the "Command (⌘) + R" keys on your keyboard.
    • This will refresh the folder and potentially expand it.
  3. Check for duplicate folders: If you have duplicate folders with the same name, it might cause issues. Try:
    • Selecting the collapsed folder.
    • Right-clicking (or control-clicking) on the folder and selecting "Get Info".
    • Check if there are any duplicate folders with the same name.
    • If you find duplicates, try renaming or deleting the duplicate folders.
  4. Reset Apple Mail: If none of the above steps work, you can try resetting Apple Mail:
    • Quit Apple Mail.
    • Go to the "Applications" folder and right-click (or control-click) on the "Mail" app.
    • Select "Show Package Contents".
    • Navigate to the "Contents" folder and then the "Resources" folder.
    • Look for the "MailData" folder and move it to the desktop (or another location).
    • Restart Apple Mail.
  5. Reinstall Apple Mail: If all else fails, you can try reinstalling Apple Mail:
    • Go to the "Applications" folder and right-click (or control-click) on the "Mail" app.
    • Select "Move to Trash".
    • Empty the Trash.
    • Go to the App Store and reinstall Apple Mail.

If none of these steps resolve the issue, you may want to consider seeking assistance from Apple Support or a professional IT expert.
