Somehow I have managed to create duplicate .pst files for 1 email account. I have the same file on C: and D:, and Outlook has them both open. If I try to delete one, Outlook refers me back to the Email account and will not delete either file. I have tried deleting 1 of the files, but Outlook re-creates it when it next is run. I do not want to delete the Email account, this will delete the files. I need some help.
