Install-AntispamAgents.ps1 Fails for Exchange 2016 CU7 and CU8

Not many organizations enable the antispam agents on their Exchange servers since they're probably paying for an additional service to do spam filtering. However, if you attempt to enable it on Exchange Server 2016 CU7 or CU8, there is an error in the script that you need to run. As of right now, CU8 is the latest update available so, this may continue in later updates.

To enable the antispam agents in Exchange Server 2016, you run the Install-AntispamAgents.ps1 script located in C:\Program Files\Microsoft\Exchange Server\V15\Scripts. However in CU7 and CU8, you get an error like this:

There are several screens of error information, but the key part is:

A parameter cannot be found that matches parameter name 'EscalationTeam'.

If you open the script and go to line 50, you'll see the following at the end of the line:

If you delete the following text from that line, the script works properly:

-EscalationTeam "AntiSpam";

Please note that this script does have a digital signature. Editing the script invalidates the digital signature. So, to run this script ensure that your execution policy is not set to AllSigned. It will run fine with execution policy set to either Unrestricted or RemoteSigned.
