How to Recover Lost and Deleted Outlook PST File
Deleting emails from Deleted Items folder should always be done with caution. But accidents happen and sometimes we delete emails by mistake. Fortunately, there is a way to recover deleted items in Microsoft Outlook.
Most importantly, you should close Outlook immediately after deleting the items. It is also important that you do not restart the program until the very end of the process. The longer you leave it open, the more unpredictable the results will be.
Your deleted files are saved as a PST file. Outlook's instinct is to overwrite a PST file as soon as it detects any changes, such as deletion of content. Our job is to recover the files before Outlook has a chance to make changes to the PST.
