Same error here. Existing 2+ year hybrid environment (2013 CU 16) that's been running fine. Re-ran the Hybrid Configuration Wizard today to replace an expiring certificate and hit this error.  It has now fouled up our connectors and we are down.  Support is so far clueless.

Yeah, I confirmed you can't create or edit any kind of inbound connector whether it's via the GUI or via PowerShell.  You always get the "Parameter Count Mismatch" error no matter what you do.  Microsoft support deleted my existing inbound connector while troubleshooting so I can't modify my outbound connector either since it does a check to make sure you have an inbound connector before saving.   I'm stuck with no mail flow until they fix this.

    I can create inbound connectors, just not set type to OnPremises. That's what throwing the exception.

      I am experiencing the same problem when trying to create the inbound connector using OnPremises option.
