Also you can remove connector thru ADSI Edit.

For removing send & receive connector you can do it using ADSIEdit.msc

Open AdsiEdit.msc.
Expand Configuration.
Expand CN=Services.
Expand CN=Microsoft Exchange.
Expand CN=<Organization name>.
Expand CN=Exchange Administrative Group (FYDIBOHF23SPDLT).
Expand CN=<Server Name>.
Expand CN=Protocols.
Expand CN=SMTP Receive Connectors.
On the right hand side, we will see all the Receive Connector
