HCW Error when configuring the mail flow

[Teka Teka]

Hi All,

im trying to run the HCW and i have the below error when it reach the mail flow configuration.

HCW0000 PowerShell failed to invoke 'New-InboundConnector': Parameter count mismatch. An unexpected error has occurred and a Watson dump is being generated: Parameter count mismatch

Thanks

I can now successfully run Get-HybridMailflowDatacenterIPs . Not sure if the rest of the wizard will work but I will give it a shot.

Worked for me as of 8am CST this morning.

I am also finally able to create the connector and verified that it is usable.

yay, our tenant is also fixed now. Create manual connector and HCW works again. But still 3 days without hybrid mail delivery, bad thing.

May I inquire the thread here to clarify something.  Were existing hybrid connectors mailflow affected by this or just the creation of new ones/hybrid wizard completion?  In other words, was any mail destined for on-prem from O365 or vice versa down?  I didn't get that existing connectors stopped working.
