If you are planning to or have recently upgraded from the Dynamics CRM 2011 for Outlook plugin to the Dynamics CRM 2015 for Outlook plugin (skipping CRM 2013), you will need to uninstall the 2011 version and install the 2015 version. Today’s blog has all the steps you need to get this done, so let’s get started!


Once you upgrade your CRM system, you need to fully uninstall the old version and install the new version fresh. Complications can arise if CRM 2011 components are left on the workstation, as these sometimes do not get removed during the uninstall. It’s important to ensure that the system is clean before attempting to install the new version.

Here are the quick steps:

1. Uninstall the Microsoft Dynamics CRM 2011 for Outlook plugin.

2. Remove any remaining CRM components left behind including MSCRM folders and registry keys.

3. Reboot the workstation.

4. Install the Microsoft Dynamics CRM for Outlook 2015 plugin.

Now, let’s go through these steps in more detail:

Step 1 – Uninstall the Microsoft Dynamics CRM 2011 for Outlook plugin. You accomplish this by navigating to the Start menu and search for “Programs and Features” or open it from the Control Panel. Find Microsoft Dynamics CRM 2011 For Outlook Add-in and click Uninstall.

Step 2 -When the uninstall is complete, we need to ensure the rest of the components are removed as well.

Navigate to the following file paths and delete the MSCRM folders. If the MSCRM folder does not exist, that’s great because it mean less work for you to do!

  1. C:\Users\<Windows User ID>\AppData\Local\Microsoft
  2. b. C:\Users\<Windows User ID>\AppData\Roaming\Microsoft

Note: Replace <Windows User ID> with the workstation user you are logged in as – for example: C:\Users\firstname.lastname\AppData\local\Microsoft

Remove any remaining Registry Keys including the following keys and any references to CRM:

  1. HKEY_CURRENT_USER\Software\Microsoft\MSCRMClient

Note: Always backup your registry before making changes. If not done correctly, removing Registry Keys can corrupt an entire workstation. Make sure you are completely comfortable making these changes or contact your system administrator.

Step 3 – After the last remaining components have been removed, restart the workstation. This will clear out any remaining components left in the cache.

Step 4 – Download and install the Microsoft Dynamics CRM 2015 for Outlook plugin available here.
