At the end of the mainteinance make sure to run again using the "endMaintenance" parameter.

.PARAMETER csvFileName
Path to the CSV file containing the servers. Format should be as follow:
ServerFQDN, Alias
Exchange3.gsxinternal.local, Exchange3
exchange2.gsxinternal.local, exchange2

.PARAMETER templateGuid
Determines which configurations should be impacted according to their template GUID. By default 'd854f97f-a776-4a7c-a886-91790c6c3c31' will be used for all Exchange Mailbox Servers.
