I am dealing with an oversized PST file that has crossed 20GB and is now causing slow Outlook performance and frequent lag during mailbox operations. I want to reduce the size of this PST safely without risking any data loss. I have already tried basic cleanup like deleting unnecessary emails, but the PST size has not reduced much even after emptying the Deleted Items. Can anyone guide me on the safest and most effective methods to shrink or compress a 20GB+ PST file? Also, if there are any reliable tools or manual steps to compact the PST without corrupting it, please share your suggestions.
