I would like to create a retention tag to apply only to items of a specific message class.

Is this possible?

Am using Exchange 2013.

Hi,

The answer is no. Because there is no option about items of a specific message class in retention tag.

Refer from

In addition, if you want to remove messages by message class, we can use the script in the link below.
