Apple Mail Exporting Mailbox

[Matte2]

I use Apple Mail and have thousands of emails over a 6 year period that are in my inbox that I want to transfer to a USB drive. I right clicked Export Mailbox and then an .mbox file appears on my desktop but the size of it is only 62MB, which doesn't make sense because I have thousands of emails. Furthermore, the word partial is in the title of the exported mailbox.

How can I make sure all my inbox emails are exported?

When I exported the "Sent" mailbox to the desktop the box file totaled 1.3GB which made sense, but the "Inbox" isn't exporting very much.

Any help would be appreciated. I really would like to save and transfer these emails, vs having forward them all to a free email addresss website.

I'm thinking that over the years, some attachments may have been "lost", some emails may have become corrupted, etc. -- events that would prevent Mail.app from "exporting" them.

Something you could try:
- Get an external drive large enough to hold the Mail folder:
- Go to home/library
- Locate the "Mail" folder
- Copy the ENTIRE Mail folder to an external drive.

Now, everything should "be in there". Same as it is on your internal drive.
If you wanted to access it in the future, I believe you'd have to "re-import" the whole back into Mail. But again, everything that was previously there, should still be there.

Once you've done this, you can manually "delete" the emails or folders (containing the emails) that you no longer want on your internal drive.

Create a folder on the new drive. Select the emails you want to move to that drive. Drag them to the folder on the new drive.

If the folder hierarchy is important you may need to create each folder and drag and drop by folder.
