We will get back to you as soon as possible.

If you don’t have a valid license, you can get a trial key on the product page.

After the setup is complete, you have to deactivate and then re-activate the “Calendar E-Mail Extension” site feature. Go to the site settings of a Calendar E-Mail Extension site, click on Manage site features and deactivate and re-activate the Calendar E-Mail Extension feature.

Finally restart the SharePoint Timer Service on all servers in the SharePoint farm.

Offline key validation

If your SharePoint Server is located behind a proxy or is not permitted to access our online key validation service you will need to perform an offline validation to successfully complete the setup and activate the solution. For online validation go to The unvalidated surety file which you need to upload is created during the setup process. Upload it, then validate it and download the validated surety file to the setup folder and run the setup again.

After the installation

After the setup succeeds continue with the configuration SharePoint Calendar E-Mail Extension Configuration Guide.

If you haven’t yet configured SharePoint incoming and outgoing E-Mail, read this guide SharePoint incoming and outgoing e-mail configuration for the Calendar E-Mail Extension.


If you want to uninstall the solution completely, you have to delete all calendar lists that were created from our template. Otherwise you’ll receive an error when opening a calendar after the uninstall. You also have to deactivate all site collection and site features.

When all the features are deactivated, you can uninstall the solution. Re-run the setup and choose Remove after the system check.

Remove the solution

As an alternative, you can also retract and remove the solutions from the farm solutions in central administration.
