How to Export a PST File from Outlook 2010

1. On the main tabs, select File.

2. Select Open and then Import.

3. In the Import and Export Wizard window, select Export to a file and click Next >.

4. In the Export to a File window, select Outlook Data File (.pst) and click Next >.

5.  In the Export Outlook Data File window, select the folder from which the data will be exported and click Next >. (Note that selecting the top level account folder will save all e-mail messages, contacts, calendar information, etc. to the saved .pst file.)

6. Confirm file name and save location (or Browse... to a new location), select desired Options, and click Finish. (Note that the suggested option is to Replace duplicates with items exported to avoid potential duplication in the saved .pst file).

7. Upon initial creation of .pst file, Outlook will prompt for an optional password. Click OK without setting a password, as the additional layer of security may cause issues when importing the .pst into a client or Exchange server.   

8. Outlook will export the .pst to the location set previously.  When complete, the file will be available in the specified location. (Note that larger .pst files can take several minutes to process).
