A friends old computer crashed and has now setup a new computer with Outlook 2016. He was using Outlook 2007 with POP3. Lukcily, everything was backed up, so I reloaded the .pst file into Outlook 2016. Unfortunatly, it appears some of the folders are missing.

I've checked the pst with a number of PST viewers, fixing tools and different backups and none of them are showing any of the missing folders.

He says the folders were in a different folder tree which lead me to believe it was setup under another account. However, we went through all the accounts he had and none of them have the missing folders.

I'm at a loss of where these folders have gone. does outlook store folders in a different place sometimes? What else could be the problem here? Really at a loss and these emails are vital to my friends business.

Thanks for any help or suggestions!

UPDATE 1

I've got my hands on Outlook 2007, the software version that was installed before the crash. I've loaded the pst in and the folders are still missing. Therefore, I followed Microsoft's steps to try to recover anything and nothing has new has appeared (not even a lost & found folder). A snippet of the log from scanpst.exer is below. Can anyone make heads or tails of what it means?

  • I would place money on the fact your friend is just remembering wrong. Unless you skipped a file, if the folder isn't there, then it isn't there. Its not clear what your question is, if you have verified the emails/folders are not contained with the .PST, then you are looking at the wrong .PST file. – Ramhound Dec 9 '15 at 15:21
  • @Ramhound that's my worry. I've scanned his backup for .pst files and checked all of them, none of them have the folders or emails he mentions even though I have follow up emails to the missing emails. – David Dec 9 '15 at 15:25
  • Is it possible these .PST files were restored from a backup before the crash? Are these the only emails that are missing? Are the emails still on the server? – Ramhound Dec 9 '15 at 15:27
  • @Ramhound No, there are folders missing as well that have been present for months, but don't appear any ANY backup PST from any date in the past 6 months. It leads me to believe these folders/emails weren't stored/setup in the traditional way and thus why they aren't in the PST. – David Dec 9 '15 at 15:43
  • You are sure IMAP wasn't being used and .PST was simple used to archive the emails? – Ramhound Dec 9 '15 at 15:46

This should be a comment, but my bad reputation prevents me from adding one.

Is there a way for you to make sure all PST files were in the backup? Some backup methods do not cover open files and thus will not backup a PST file currently in use by a running Outlook instance.

To my knowledge, Outlook stores all its e-mails in PST folders, i.e. there is no other location other than PST folders to look for Outlook e-mails. Your comment suggests you are aware that there may be multiple PST files for a single Outlook account (e.g. PST files are created automatically when having multiple e-mail accounts as well as by Outlook's archiving feature).

Since I don't know your backup software, my last hint is to ensure you're not missing PST files in hidden or system folders inside your backup.

  • It's CrashPlan that is used. I've also dragged the files off the old harddrive, just in case it wasn't backuped using CrashPlan. there are no additional pst files. – David Dec 10 '15 at 10:10
  • Weird. I have not much hope to be honest. Have you checked for OST files? (cf. support.office.com/en-au/article/…). If you are really desperate, you could try to restore the user account as described here: jephens.com/2008/10/14/…. This would require reading the registry from the backup (described in superuser.com/questions/111732/…). – Robin Dec 10 '15 at 14:50
