Background
There are currently known issues with Microsoft activation servers affecting Remote Desktop Services (RDS) CAL licenses on Windows Server. This issue affects online activation of RDS licenses via the license wizard.
When attempting to activate RDS CAL licenses online, you may often see the following error message:
“The licensing agreement data provided to Microsoft is not valid. Check all information, make the necessary corrections, and submit the request again.”
The issue is not caused by incorrect license information or input errors, but by temporary problems with Microsoft activation servers.
Until Microsoft resolves the issue, phone activation is the only functional method to successfully activate RDS CAL licenses.
