A while back, while performing a migration to Office 365, I had to convert a Distribution Group into a Room List. However, due to the nature of the migration, I didn’t have access to an on-premises Exchange to use the Shell and convert it, so I had to resort to using ADSIedit. So how do we do this using ADSIedit?
There is a reference field that specifies what a recipient type is, as far as on-premises AD/Exchange is concerned, Recipient Type Details = msExchRecipientTypeDetails.
As many other AD attributes, these are represented by an Integer value in AD. Here are all the possible values for Recipient Type Details:

As such, all I had to do was locate the Distribution Group in AD, update its msExchRecipientTypeDetails attribute to 268435456 and wait for DirSync to replicate the change.
