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 think I am too late for answering this question but I want to share my opinion regarding this problem because this will be helpful for other users.

    Suppose you have multiple .pst files and wants to merge them into one single .pst file then you can easily do this by any application. I would like to suggest you this site:
    Utility available on this location will also help you to merge other Outlook pst items like contacts, tasks, db-journal, .oab, .dat, .FAV, .srs etc. You can also remove duplicates via this utility and it also provides you a choice to include/exclude deleted Outlook .pst files.

    You can easily consolidate all emails into singular Inbox, Sent, Deleted, Contact and Calendar files.

  • 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......"

  • To combine two PST files in MS Outlook 2010, you can use its Import and Export feature. First create a new Outlook data file or PST and follow the steps given below: 

    • Locate the two PST files which you want to merge. 
      All the files (new PST and other two files) will be highlighted in the navigation pane. 
    • Click File > Open > Import.
    • Select "Import from other program or file" and click Next. 
    • Select "Outlook Data File (.pst)" and click Next. 
    • Click Browse and select the file from which you want to import and click Next. 
    • Select the folder(s) which you want to import into the new file. 
    • Click Finish. 

    The selected folders will be imported to the new PST file. Do the same to import data from the next PST file. By doing this, all the selected data will be merged into the new file. Though it is very safe, but you must create backup for your original files. 

    I can also recommend you a third-party tool for combining multiple PST files. Try SysInfoTools PST Merge tool and merge your multiple PST files into a single file. You must check its free demo version.
