I have installed Exchange 2007 SP1 into an existing Exchange 2000 organization and configured public folders to replicate to the 2007 SP1 box which is appeared to do without issue including the hierarchy. I see no errors in the app log and have tracked messages from the servername-IS@ addresses which also appear to be flowing without issue. The problem is that some public folders still do not have the same item count. For example, one folder on the E2K box has an item count of 1912 while the E2K7 box has a count of 1111. I keep reading that it just takes a long time to replicate but it's been three weeks now and the total info store size for public folders on E2K is only 100MB. A week after the numbers above, the same folder on E2K has 1917 and the E2K7 box has 1116 so it seems as if maybe the replication only takes a certain date range maybe? How do I get them to match up??
