I use now EXCH2007 as production System.
For Migration I have installed EXCH2013 into the environment on a seperate server.
Now I have major problems and for some reason I cannot create any mailbox on 2007 or 2013.
Now my question, can I unistall all EXCH2013 servers without problems ?
Or do I have some objects which are changed to version 2013 and this is not changeable anymore ?
