Repeat this procedure for any other mailboxes you’d like to archive-Sent, smart mailboxes, and mailboxes that appear under the On My Mac heading, for example. INBOX-1.mbox, INBOX-2.mbox, and INBOX-3.mbox. So, for example, if you have Gmail, AOL, MobileMe, and AT&T accounts and inboxes for each, Mail will export four mail archives, called INBOX.mbox. Mail will create as many mbox files as you have accounts listed under Inbox. Choose a location and click the Choose button. In the sheet that appears you’ll be asked for a destination for saving the exported mailbox files (called “mbox” files).

In the meantime, you can access your mailbox through the web access: - (Right) click on the Inbox in Mail and choose Archive Mailbox from the contextual menu. We recommend waiting until a weekend to start the transfer so that you can be out of the office while it runs.

Please note: Depending on the size of your archive, this process can take anywhere from several minutes up to a day or more, and you will not be able to use Outlook on your office computer during this time. This tutorial will walk you through the steps of moving your local archived emails into the online archive. Office 365 introduces an online archive feature that will allow you to access your archives from anywhere and doesn't have the corruption issues that we experience with PST files. This was an imperfect system because the archive file type (.pst) doesn't perform very well on server storage, but if we moved the file to your local desktop's C drive, it might be lost in a hard drive crash or Windows reinstall. In the past, we set up Outlook archives so that email could be stored on the A&S file server and free up the limited space on the Exchange server.
