Saving Outlook Messages

You didn't mention what version of Outlook you are using but it really doesn't matter. Outlook stores all the personal folders that you create in a PST file (personal folders file) You may have multiple PST files on your computer. To check this, from outlook click on tools > services > it will list the personal folders file. To copy your email, simply copy this file to your e drive. If you have any questions let me know.

If using MS Outlook 2000 or later, a Personal Folders Backup utility is available for free download. Once installed you can automate the backup process. Visit the Micosoft Knowledge Base article listed below for further details and a link to download the add-in:

As an alternative, you can use the Import/Export feature in Outlook to create a copy of an Outlook folder in various different formats including a text file.

The Archive feature in Outlook will move specified mail files from your default PST file to an "archive.PST" file if you wish to reduce the size of your default PST file.

Good luck.
