Jane, While holding down the Option key, launch Outlook directly by double clicking on the Application. Once the program launches you will be asked it you want to Compact the Database and you choose no. Then it will ask you if you want to do a Complex Rebuild and you choose yes. Once it finishes it will give you a message about "Old" files. So you then look for a folder called "Identities" that is located in the Microsoft User Data folder. Inside of the "Identities" folder look through all the folders for all the files that say "Old" on them. Move them to the desktop, relaunch Outlook and see if your mail is intact. If so, you can delete the 'Old" files. Most likely one of the files in the "Identities" folder is causing this problem. If the above fix does not work, you may want to back up the "Identities" folder and then try systematically dragging a file at a time out of the "Identities" folder until Outlook launches.
