How to merge two Outlook 2010 pst data files?


All replies

  • Easy way: with the one you want to use open in Outlook and the other one not in your profile, go to File, Open, Import.

    If you only want to merge some content, open both pst files in outlook and drag between folders. For calendar, use a list view to see all of the appointments.

  • I set up my new office 2010 Outlook first and it delivered email from the past few days into the new program. Meanwhile, I put my .pst file from my old computer/outlook into the new outlook folder and renamed the new .pst file (new) when I re-opened 2010 outlook, all my (old) .pst data was there, but none of the new emails.

    I opened the other renamed (new) file, but it was empty? I also tried to import from it, but keep getting a message about "importing to a location that doesn't support Unicode, .... lose multilingual data.... choose location that supports unicode......"

  • There can be many ways to do same thing but, PST merge program is recommended for users as it supports 3 types of merging processes. You can merge PST contacts, PST files and all types of PST items. It saves times because the combining file process is fast. 

    Just checked this tool, worked perfectly.
