Error says Windows can't find 'MBX'. Make sure you typed the name correctly. Also get a similar error when trying to look at ExchWeb. One side note, I notice that when I click on basic settings it points to \\.\BackOfficeStorage\domain.local\MBXas apposed to domain.com "I went through all the processes and registered the .com cert via EMC as documented by MS. Not sure if I'm missing a step?

Can you elaborate on what it is you are actually trying to do?
