What do I do if my .pst file approaches the 2GB size limit?
If a .pst file exceeds 2GB, Outlook can’t open it. The pst2gb.exe tool, which you can get from Microsoft Product Support Services (click here to download), can help you recover most of your data, but you probably won’t get it all back. Try to keep any .pst files well under that 2GB limit. To maintain reasonably sized .pst files, delete messages you don’t need to keep, empty the Deleted Items folder regularly or automatically, and occasionally compact the .pst file to remove the empty space that remains after you delete items. To compact the .pst file, right-click Outlook Today, click Advanced, and click Compact Now. If you encounter difficulty using the crop tool, call the HelpDesk at 2-4242 or phone/email the CIS contact at the bottom of this page.
