I am using Redemption to get the list of emails in a folder on
Exchange Server. For this i'm using ICS

the synchonizer has the following method
Synchonizer.SyncItems(strPreviousSyncData, strSQLRestriction)

my question regards the sql restriction

I need to get only emails from a particular folder thus where the
MessageClass = 'IPM.Note'

how can i exclude other items and get only emails?

I tried something like MessageClass <> 'IPM.Note' but it did not work

help would be greatly appreciated

thanks
Ian
