Google Sync and Outlook 2010 Beta

    If you are like me, you usually rush to download the newest beta’s that are released, and for some bragging rights, you loose some functionality.  That was the case with me and my download of the Office 2010 Beta, I use Google Sync to sync my Google and Outlook calendars, yet the Google Sync doesn’t support the new 2010 Beta.  Now a geek like me isn’t just going to sit here and go sync-less until 2010 Officially comes out and Google Sync supports it.  I decided to play around with it, and I got it to work…and here’s how.  But before I start please make sure you read all directions thouroughly before starting and make sure you have a full backup prior to attempting the change.

  1. Get HxD Editor
  2. Goto you Outlook 2010 Installation Folder and Backup your Outlook.exe file (C:\Program Files\Microsoft Office\Office14), I suggest copy and pasting the Outlook.exe file into the same folder.

    Backing up Outlook.exe before making modifications
  3. Open up HxD Editor and browse to Outlook.exe
  4. Click on Search and Then FindUse the Search Function in HxD
  5. In the search field search for 14.0.0

    Find the Version Number in HxD
    Find the Version Number in HxD
  6. You should find it, only one time

    Found 14.0.0 in HxD Editor

    Hightlight the 4 (DO NOT DELETE IT)
  8. Replace the 4 in 14.0.0 with a 2 making it 12.0.0

    When Highlighted Change the 4 to a 2
  9. Save the change…and your done, your Google Sync should now work with 2010 Beta, because we make Outlook 2010 Beta, report to other programs it’s outlook 2007, which is a supported version.

    Save the changes to the Outlook.exe

Please remember that when doing this please, read all the directions first and make sure you have a complete backup before attempting this change.


  1. Can’t believe someone put an ad in the response to your fix. Question – I can’t replace the “4” with a “2”. Error message says “Can’t open C: *\outlook.exe” for write access. Access is denied. I confirmed that the properties allow write access to the file. Am I missing something? Thanks

    1. John,
      It sounds like something still might be using the outlook.exe file, if you can’t modify the file, then try to modify the backup outlook.exe that’s in the directions, see if you can modify that. If something is using the file, then the backup file should not be being used.

  2. Same issue as JohnW – I tried to replace the original and the backup Outlook file – got the same error message. Running the developer version of Office 2010 (60 day trial)

  3. Solved – change the file permissions for the Outlook.exe file so that you have full control, not just read/write.

  4. Heya i’m for the first time here. I came across this board
    and I find It truly useful & it helped me out much.
    I hope to give something back and aid others like
    you helped me.
