You might want to use the Inbox Repair tool in the following situations: • You receive a message that Outlook can't open your data file • You receive a message that Outlook can't open the set of folders • You think your Outlook data file may be damaged If you're using an Exchange email account, you can delete the offline Outlook Data File (.ost) and Outlook will recreate the offline Outlook Data File (.ost) the next time you open Outlook. Notes: • The Inbox Repair tool doesn't connect or analyze any data stored in an Exchange mailbox. The tool only looks for errors (corruption), and if there are any, gives you the opportunity to allow the tool to fix those errors. If you can't start the Inbox Repair tool, you should try to repair your Outlook program. • We recommend backing up your existing Outlook data file before you start the Inbox Repair tool.
