Hi all,

We have a client who has somehow managed to duplicate their entire mailbox.
So every email is there twice.

What would be the best way of removing these duplicates?
Is there any recommended software?
I've taken a look but not sure if these are geared towards PST?

I guess an export to a PST and then using one of the programs may work.

Thanks in advance,
Arran

Can you not export to PST and choose do not export duplicate items.

Then clear mailbox and re-import with no duplicates?

Thanks for your comments.

Jerseysam: I have tried your solution and unfortunately this hasn't worked, the PST is exporting the duplicates even with 'do not export duplicate items' switched on. :(

Going to try amitkulshrestha's solution and will report back with my findings.
