If you ever install Microsoft Dynamics CRM outlook client and you found that your Outlook 2013 or 2010 ribbon buttons and tabs have completely disappeared, then this is usually caused because of registry keys that are left over from an earlier version of Microsoft Outlook.
You will find that Outlook ribbon tabs and buttons reappear if you remove or disable Microsoft Dynamics CRM client for Outlook, but that doesn’t really solve the issue.
Please note that this issue resolution includes changing the registry. Make sure that you back up the registry before you change it. Please make sure that you know how to restore the registry if a problem occurs. This post is provided as is without any warranties.
To resolve this issue, follow these steps :
- Exit Outlook.
- Click Start, click Run, type regedit, and then click OK.
- Locate the following registry subkey:
- Right-click the 2.4 registry key, and then select Export. Save the export to your desktop to create a backup.
- Right-click the 2.4 key again, and then select delete.
- Start Outlook.
You should now have all your Outlook ribbon buttons and tabs back including Microsoft Dynamics CRM ones. You won’t need to disable or remove CRM outlook client to get your tabs back.
