    To those attempting to migrate from an older version of Outlook to a newer version, this can be done, but you have to be smart about the process. Retail Outlook allows 2 installs to be active at a time (1 desktop & 1 laptop), so before you install your new office to your new machine, install the old one. Then migrate as above, and then upgrade.

    Should the Profiles Key be backed up and deleted (the one on the computer that you are moving to) before importing the Key (the one on the old computer) with the settings you want over to the new computer?

      @Kay: If you haven't created a new Outlook Profile on the new computer, there is no need to backup the Profiles key.

    I am trying to migrate Outlook 2007 on a Windows 10 Machine to Outlook 2016 on a Windows 10 Machine. Unfortunately on the original machine I can't find the "Profiles" folder in the registry.
    One more question: can you be more specific on how to change the name temporarily to allo for the import to take place?

    Thanks a lot!

      @Aldo: I suggest to transfer manually the PST file to the new machine and to create from scratch all the e-mail accounts.
      Also, is better to add a new account in Windows 10 (with the old username) and after Outlook migration to rename the new account.
      To rename an account in Windows 10 go to: Control Panel > User Accounts > Change your account name.
      To add an account go to Settings > User Accounts > Family & other people > and select the "+" symbol under the "Other People" section.
      p.s. Windows 10 with Outlook 2007: Profiles folder in registry = HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles

    I did the procedure, but when I started outlook it requires the * .ost file in the AppData folder. How to skip this validation?

      @Leonardo: You cannot skip this validation. Copy the *.ost file to the AppData folder to solve the problem.

    Thank you for your article and it was very helpful.
    Question: Is there a way to make a script file (*.bat) to do this for me??
    I am using outlook 2013.

    Thank you for your help in advance.

    Final addition: got it working by:
    1. putting a copy of the outlook data file from old computer into a newly made folder on similar path in new computer
    2. deleting email account that came over with data file
    3. adding new email account with identical settings to that which was deleted

    Isn't clear if any settings were actually duplicated on new machine, but it least it works!

    Addition: I tried copying my outlook data file from the old computer to the new one, which allows me to open outlook, however, this just brings up all the data that existed. Send/receive report errors, citing 'outlook data file cannot be accessed'. I may have really screwed this up…

    @laknost: thank you, but I'm still confused. Everything above is for export/import of a .reg file but this is a .pst file. It isn't clear to me where this .pst file comes from the registry change above. Should I also be exporting an outlook data file from my previous computer?

    Alternately, is it possible to 'undo' the import above? My other option is to set up outlook manually, but now I can't since it's looking for this file and won't open. Sorry to be a pain, this looked so easy and I must be missing something obvious

    Hi! what can I do if i'm backing up Outlook 2010 and restoring it to Outlook 2016, the Profile folder is in a different KEY location. Anyone can help?


    • lakonst
      May 12, 2016 @ 8:42 am

      @Alexander: (Temporarily) change the username in Windows (using the same username as in old machine) to make the import. Then change it back.

        Awesome tip! I'm also having issues with the import. Going from Outlook 2010 to Outlook 2013. Tried changing username as instructed above and reimporting settings, regardless get message "The path specified for the file C:\Users\User\Documents\Outlook Files\emailaddress.pst is not valid" and then it sends me to a place to choose the file location. thoughts?

          @Jesse: Navigate to the location where you transferred the Outlook.pst file.

    Thanks for this article. I followed the instructions and was able to transfer my settings to a new computer successfully, even though I am a Google Apps user and sync to Outlook using Google Apps Sync. I transferred the settings before running Google Apps Sync and then when I opened Outlook, all my settings were there from the first computer.

    Hi, I have a problem. I can´t import since my new user on Windows 10 has a different name than the one exported from the registry on Outlook 2010 from my previous laptop. What should I do?

      @Jose: (Temporarily) change the username in Windows 10 (using your Windows 7 username) to make the import. Then change it back.

    Thanks for your effort but there is no such a key. I'm using Windows 8.1. Any idea?

      unfortunately, I haven't try this method in Windows 8.1 yet.
