How to Disable Compatibility Mode in Outlook?

If you are using Outlook 2010 then you need to navigate to your C drive, Program Files.

Inside Program Files you will find Microsoft Office folder.

Open that folder and go to Office 14 subfolder inside that.

For Outlook 2013 or later, you will be able to find Office 15 folder inside your C Drive (If that is the installation drive for your operating system), Program Files/Program Files X86 (Depending on the version of your outlook 32bit/64bit).

Go to Microsoft Office and find Office 15 subfolder inside that main folder.

Once you find the Outlook.exe file inside Office 14 or Office 15 folder depending on which version of outlook you are using, right click on it and choose Properties then click on Compatibility tab.

Uncheck the box ‘Run this program in compatibility mode’ and click Apply.

Now click OK and you are done.

You have successfully disabled compatibility mode for your outlook application.

And finally, if you are using O365 and not aware of the path where your Outlook.exe resides then follow the below steps.

  1. Click on Start Menu and find Outlook there.
  2. Right Click on Outlook from start menu, Select More and click on Open File Location.
  3. That will open stat menu program folder for you.
  4. Find Outlook inside that folder and Right click on it then click Open File Location
  5. Now it will take you to the Root Folder of you MS Office (Program Files > Microsoft Office > root > Office16).
  6. Right Click on Outlook
