I just clicked through the on-prem AD DC Connect app the first time around and it failed to match my accounts; this one which is some kind of 365 entity with a huge schema and life of its own, so now I have two.
One is the principal account for a 365 space, and the other can only be synched one way. I tried editing my SID with the attribute editor in AD Users iand Groups , but that field is read only.
How should I resolve this issue? Strangely, MS knows they are the same entity as logging in with either one wilil land in the sasme
