First off, head here to download the ControlBrowserSupportForOrganization_1_0_0_0_managed.zip solution.
Next, head to your UR 12 enabled CRM organization and install the managed solution you downloaded above. To do so, go to Settings –> Solutions –> Import –> Browse to ControlBrowserSupportForOrganization_1_0_0_0_managed.zip and follow the wizard.
After the solution has finished installing, we can now configure the message that will be displayed to the non-IE users. To do so, go back to Settings and then to Customizations. Click Customize the System.
This brings up the Default Solution. Now click on Web Resources on the left and find the HTML web resource named Organization Browser Support Message.
Double-click the Organization Browser Support Message resource to open it up. You will be presented with the dialog below. Edit the highlighted tokens to change the Organization Name and Administrator Name to the respective values for your CRM organization.
Now save and publish the Organization Browser Support Message resource. Then access your CRM organization with a non-IE browser such as Google Chrome. You should be presented to a similar message as shown below:
If you have users (such as any developers) that will need to access your CRM organization in a browser other than IE, you can open up their User record in CRM and give them the “Any Browser Allowed” security role. This will enable that user to browse to your CRM organization using any supported browser.
Props again to Jim Daly for a great solution that enables an organization to not adopt multiple browsers so abruptly!
