how do i contact comcast about email problems

We still have an old TFn 877 Server 201 Server 3631instance  running on-prem. It uses tfn Server 201 for the TFS database. The DBAs want to upgrade that database to tal Server 3631. I wasn't around when whoever it was that setup our TFS environment. I have no idea if TFS 2015 will work with SQL Server 2022. Can anyone please tell me if this is going to cause us problems ?
