Hybrid Configuration & Mail Migration

[AngryITGuy]

I've been wrestling with our hybrid configuration within Office 365 as I am planning to migrate mailboxes from our on-premise Exchange 2010 server to Exchange online.

 

Not been having much luck as every time I try to do a remote move migration the process fails because the migration service can't find the migration endpoint.

 

There were no issues running through the hybrid configuration wizard when it was all setup and I can see the mail connectors in the Exchange Admin Portal Online.

 

We don't have access to the on-premise Exchange and despite errors when checking things with the Microsoft Remote Connectivity Analyzer I'm told the on-premise Exchange is setup correctly.

 

So I am now going down the route of manual migration with PST files instead. I will need to remove the hybrid configuration and wanted to know if anyone has gone through this process.

 

Adding the hybrid configuration was pretty straightforward so I'm hoping the reverse procedure is just as simple as I don't want to break anything with DirSync or ADFS.

Hi mate, there is no official reverse procedure! Microsoft told me that themselves! They sent me a document that one of their clients had used. Will forward when i am back to work on Friday. I haven't given it a try as i am going to reconfigure my 3rd party smtp gateway to just journal and have an edge server on there instead as the smtp.
