Can't move Reference Files

Is it possible to provide small test case so that the files can be examined?

Check the following option in the reference dialog:

If it says yes, then you will not be able to change the reference as it is geographically reprojected into the active file.

Agree with Tim Hickman, your reference is most likely geographically reprojected (IE, uses a GCS - Geocoordinate System) when files are referenced using this method they are unable to be moved or scaled

here is a trick locate some elements in the reference that you can find easily by eye now draw a yellow big circle at two of these centred on the elements now detach ref and re attach but use top as the attachement  now  try to place near your circles  you should now be able to move the reference to line up with your circles delete the circles now as its not reprojected anymore  you can more to your hearts content......

Alternative create an empty file with your standard datum, now attach reprojected your reluctant ref file and merge it now your new blank file can be renamed to  xy_ z.dgn  where xy is the active datum name ( ie amg66) and Z is the original ref name.. you can now attach this file to your first original active file world coincendent  and thus  you will be able to move scale rotate that ref attach to your will....
