Just confirmed with Microsoft this is an issue with a specific datacenter and that they are working actively on an internal case to resolve. Next update will be 9 PM UTC 5-20-2017.  They are specifically attaching customers tenants that call in to their case so they can go and rollout the patch.

We're having this issue too (in Office 365, trying to create an inbound connector). Do you know if the fix they're working on will automatically address our issue once it's fully rolled out, or do I need to explicitly call into support so they can patch our specific instance?

    No I think they are rolling out fix to everyone. Not sure if a ticket will get a customer tenant priority or not. I doubt it

      Any ETA on this?.. I'm doing a migration this weekend and it looks like the same problem.

        Standard line from Microsoft is "24 to 48 hours".
