Hi there,
I'm seeing some odd issues with DirSync and Migrations so I'm wondering if the 2 are related. We have a parent domain, for example, domain.com, then we have 3 child domains, say a.domain.com, b.domain.com & c.domain.com.
When I run start-onlinecoexistencesync as my account (member of Enterprise Admins and Domain Admins of the parent & child domains) then DirSync runs as expected. However, when it runs automatically with the MSOL_dd000000000 account then I get failures on all domains with the following message:
Error 8344 Insufficient access rights to perform the operation
I'm also seeing the following error when trying to set up the migration endpoint:
We couldn't detect your server settings. Please enter them. The ExchangeRemote endpoint settings could not be determined from the autodiscover response. No MRSProxy was found running at mail.domain.com
I'm wondering if this is because of the DirSync error (I was reading that write back errors can cause unexpected problems with Exchange Online). I We are running an F5 that had SSL offloading turned on, but we've disabled this and allowed traffic for the MRS through to the Exchange servers, so I'm not sure if something is not quite right with the F5, or if it is related to the DirSync errors.
Has anyone run into this before?
Thanks
