Hi,Did you try opening adsiedit and then look for the second occurrence of an e-mail policy of type NS (as explained in the article - just forget about the faxmaker)Leif

Yes I have and there are two more entries in there. MS: Org/Org & CCMAIL: at OrgI've also been trying to update the schema Manual through setup.com and I am failing at the /PrepareAD step which prepares the forest.

I tried removing the MS: Org/Org & CCMAIL: at Org entries and this allwed the /PrepareAD command to run. Then I placed them back and now setup seems to be working. Not sure exactly what this is, maybe it was a replication issue and the deletion of those other two entries triggered replication. Thanks for the help.
