I have been unable to flow data from AD's msExchMailboxGuid (single, octet) to a single valued string in MV. I used the expression ""+msExchMailboxGuid for the mapping in ISR but all I end up with in the MV is system.Byte[] and not value. However, ADDS MA's CS seems to show the correct value. Does anyone know how this attibute may be synchronized into FIM? Thanks.Anu

You need a binary attribute in the metaverse. See objectSid as reference. Cheers, MarkusMarkus Vilcinskas, Knowledge Engineer, Microsoft Corporation
