First, if you’re observing this downloading message at the bottom left of your Mail app’s sidebar and it’s only there for a relatively short time, this is normal. This message means your Mail app is syncing across your various email accounts. Even though it uses the term downloading” it’s actually checking for any syncing between accounts. So, the words of wisdom here are: IGNORE IT.

But if your problem is more than just that message, you need to put your investigative skills to test. The first thing to try and rectify this situation is to take your Mail Account offline. With your Mail App open, navigate to the Menu Bar and select Mailbox. From that drop-down menu choose to Take All Accounts Offline. Once that completes, return to that menu and this time select Take All Accounts Online. See if that solves the problem.Mail App Always Downloading on Mac? How-To Fix

Turn Off and Back On Problematic Account

If not, check and see if this problem is happening on one particular account or all of your mail accounts. If it’s only happening on one of your accounts, turn off that account and then add it back in again.

Do this by going to Mail > Accounts or  > System Preferences > Internet Accounts. Then from the left pane, select your problematic account and choose the minus sign. You’ll see a message asking if you want to delete this account from all computers using iCloud Keychain (if applicable), select “Turn Off Account.”Mail App Always Downloading on Mac? How-To Fix

Sometimes, you MacBook pauses a large download to save energy when your MacBook is using battery power. If that’s the case, click the button in your Activity Monitor to resume downloading.

Rebuild It

If your problem wasn’t a paused download, try rebuilding and reindexing your Mailbox. It’s best first to delete any email that in your Trash and your Junk folders BEFORE you rebuild.

Rebuilding a mailbox updates the list of messages it contains. To rebuild:

  1. Select a mailbox in the Mail sidebar
  2. Choose Mailbox > Rebuild

Rebuilding Mailboxes takes a lot of time and once you start there is no pause or stop button, so proceed with caution. Additionally, you must repeat these two steps for each one of your Mailboxes.Mail App Always Downloading on Mac? How-To Fix

And when you rebuild mailboxes for IMAP or Exchange accounts, all the messages AND attachments stored locally on your computer are first removed and then downloaded again from your mail servers back to your Mac. That means you’ll use a lot of your network’s bandwidth. ALSO, your mailbox may appear empty until the download is complete–this is normal.

ReIndex Your Mail

Once you rebuild, take a look around your Mail app and mailboxes. If you are still having issues with downloading messages, Mail fails to launch, or any other problems, it’s time to try a manual reindexing.

The biggest difference between Reindexing and Rebuilding is that while rebuilding allows users to select individual mailboxes to be rebuilt, reindexing affects ALL Mailboxes.

Reindexing is indeed the nuclear option. It’s the last stop when Mail is so unresponsive that it barely works, the search function is not correctly working, or the Mail app won’t launch at all. So again, tread with care.

To ReIndex Mac Mail

  1. Quit Mail App
  2. On your Desktop create a folder named OLDMailData
  3. Go to Finder
  4. From Finder Menu Bar
    1. Press and Hold the Shift Key (or Option Key for some Macs)
    2. Select Go > Library
    3. Locate the Mail Folder
    4. Find a folder titled “V” followed by a number (V4 in my example) Mail App Always Downloading on Mac? How-To Fix

Once your Mail app works correctly, go ahead and delete the copies of the “Envelope Index” files from your Desktop OLDMailData folder by dumping it in the trash.
