TechEd Day 1&2 from an Exchange perspective

ResolveP2 flags

In comments to my recent post on ResolveP2, several people asked me what the properties listed in;en-us;174755 meant in real terms.  So I asked an Exchange developer and got the answer: From that KB article:ADDRESS_CONVERT_SENDER decimal value 1 = From fieldADDRESS_CONVERT_SENT_REPRESENTING decimal value 2 = Used when a delegate is involved, this is who you…


ResolveP2, RerouteViaStore, and its equivalent in Exchange 2003
