Hi all,


Using Windows 10, and it turns out I overwrote my current Office 365 PST file with one that was two years old (I have no automated backups, just do them manually).  I copied and pasted the old one over the current one by mistake instead of the other way round.  I tried going into the properties of the pst file and restoring an old version but no old version was there, and also tried the same with the parent folder but no luck.  I then tried hitting CTRL-Z to see if it might reverse the overwrite and all it did was empty the folder of the PST file and not put the old one back.


Am I totally screwed, or is there a way to somehow recover the most current pst file???

Any help very much appreciated,

You can see if the old version is in the recycle bin or if an app such as Recuva can find it. It looks like you already tried this: https://www.howto-outlook.com/howto/previousversionsrecovery.htm


If none of that works, I'm afraid you're probably out of luck.

Cheers for that Allan, I'm trying Recuva and some other recovery software now. If that doesn't work there may even be some data recovery experts in my city.

If anyone else has any advice I'd also love to hear it.

You can try the PST repair tool. This tool is capable of restoring the data from the PST file. It is also safe to use, there will be no data loss.
