Recovery of uncompacted Microsoft Outlook data
Microsoft Outlook uses the compacting feature to restructure the PST file database. In theory this is a simple way of creating new room for incoming messages and other customizations. But compacting one’s Microsoft inbox folder or the sent items folder results in those items being permanently erased. So perhaps a better option is to migrate one’s Outlook PST information to online or external storage?
Another option which is even simpler to implement is to backup Outlook files on a regular basis. If you rename your Microsoft Outlook backup file and then compact your PST file and discover that you accidentally deleted files or folders the original data will still be intact on the uncompacted back up. It seems there’s a common theme that the best way to recover accidentally deleted emails is to not completely delete them in the first place. We can easily recover deleted emails from Microsoft Outlook provided we have not compacted the PST file.
