    Can anyone tell me how to identify and delete duplicate identical messages in Outlook 98, please?

    I use Windows NT 4.0, and the size of my offline mailbox folder in Outlook 98 is now 150Mb containing up to three copies of all messages I've received (caused by various human errors!). If I could remove the duplicates it would halve the mailbox size and then I could do some sensible archiving.

    But I can't find any guidance on being able to identify the duplicates without having to manually wade through all 5,000 messages one by one. Any bright ideas, please?

    Here's what you do.

    Export your PST file to another PST file. Call it backup or something and make sure it's a good backup!

    Delete all mail in all your folders. (Or create a new folder to import all the stuff into.)

    Import the PST file into your Outlook (or new folder), telling it you don't want duplicates.

    Very many thanks, Dreamboat. Why didn't I think of that!? Off to try it now, once I've managed to create enough free space for the 150Mb backup file.

    Many thanks again.

    Sorry Dreamboat, it doesn't work.

    I tried exporting the Inbox (saying no duplicates) but duplicates were exported. Then after emptying the Inbox I imported the messages back again, again saying no duplicates but they all came across.

    I guess the 'no duplicates' command just compares the imported/exported messages with the ones already in the destination folder, but doesn't prevent duplicate messages if they are already in the folder being imported or exported - which was my problem in the first place.

    If you or anyone has any further ideas on how I can isolate duplicate messages already in the same folder I'd be very grateful.
