I was finishing the migration of about 460 users to Office 365 this weekend, and they have a Barracuda archiver, so when I went to create a connector to the archiver, I also got that "parameter count mismatch" error when trying to finish it.

 

I was using an IP address for the "How do you want to route email messages? (smarthost)" screen. On a whim, I decided to throw a random FQDN in there instead to test, and it saved fine. This customer already had a DNS entry so I updated it with the correct one,but if you don't, I suggest that you just create a DNS entry, and use that FQDN.

 

Your problem may be different, but this may help someone.

I had a chat with support and completed some remote sessions and recieved this email... using the steps provided with a new Global Admin did not work, Same Error... I awate a fix... tomorrow...

 

'As discussed, it seems that you are also part of the affected tenants for Service Degradation EX102057. Title: Mail connector issue User Impact: Administrators may be unable to create or modify mail connectors. More info: This is an incremental update to provide the latest status on the issue. Current status: The deployment of the fix is 97 percent complete. We’ll provide an update on Monday confirming full service restoration.

In addition, try to add 1 more global admin that will perform adding the mail connector in Exchange Admin Center and try again.'

    My Customer is suffering from the same problem. Looks like we are in the 3% left. Need to change the connector after a datacenter migration. Production Mails are effected.

        >>>>

        I have confirmed with our Team and it appears that they are still working for the services to be back up with regards to the mail connector. They have already corrected the issue with the creation but the services are not fully working. We will be sending you another follow up once we have the update.

        Regards
