This morning, my Outlook inbox has messages with no ‘From’, no ‘Subject’, and nothing in the ‘body’. So, I’m thinking that the .pst file has been corrupted at some point. I Googled on ‘Outlook 2007 repair tool’ and came up with this Microsoft Support article “How to use the Inbox Repair Tools to recover e-mail messages in Outlook 2002, Outlook 2003, and Outlook 2007”. I followed the instructions to repair my outlook .pst file as follows:
Open windows explorer and navigate to the folder where my outlook files are stored. Normally, this would be in: C:\users\username\AppData\Local\Microsoft\Outlook, however, I’ve moved them to: My Documents\Exchange.
