- Product
- Microsoft Outlook and Dynamics CRM
- Device & OS
- not provided
- Scenario
- Using the Dynamics CRM add-in within Microsoft Outlook after a system reboot.
- Observed behavior
- The Dynamics CRM buttons in the Outlook ribbon become greyed out and unclickable due to a version incompatibility between the add-in and the CRM server.
Verify the current version of your Dynamics CRM server and ensure you have administrative privileges on your computer to install or uninstall Outlook add-ins.
Upgrade the Dynamics CRM Outlook Add-in to a Compatible Version
Resolve the greyed-out buttons by ensuring the CRM Outlook add-in version matches your CRM server's major version.
Dynamics CRM buttons typically become disabled when the installed Outlook add-in is too old compared to the CRM server instance. Microsoft requires the add-in to be either the exact same major version as the server or no more than one major version lower.
Open the Windows Control Panel, navigate to 'Programs and Features', locate the older Dynamics CRM Outlook add-in in the list, and uninstall it.
Download the Dynamics CRM add-in that matches your server's major version (e.g., CRM 2016 for a 2016 server) from the official Microsoft Download Center.
Run the downloaded installer. Once the installation is complete, restart Microsoft Outlook and check if the CRM buttons in the ribbon are now active.
Re-enable the Add-in from Outlook Settings
Manually re-enable the add-in if Outlook has hard-disabled it after a crash or version conflict.

Frequently Asked Questions
Why are my Dynamics CRM buttons greyed out in Outlook?
This usually happens after a system reboot if the Dynamics CRM Outlook add-in installed on your computer is incompatible with the Dynamics CRM server version, typically because the add-in is more than one major version older than the server.
Can I use an older CRM add-in with a newer CRM server?
Microsoft supports using a CRM Outlook add-in that is no more than one major version lower than the CRM server instance. If it is older than that threshold, the add-in will be disabled.
How do I re-enable a disabled Outlook add-in?
In Outlook, navigate to File > Options > Add-ins. Under the 'Manage' dropdown at the bottom, select 'Disabled Items' and click 'Go'. If the CRM add-in is listed, select it and click 'Enable', then restart Microsoft Outlook.
