I have an Exchange 2003 SP2 Org with multiple servers in multiple sites across the country. Our Public Folder database is quite large and quite a bit of it replicates to multiple sites. I frequently get Hierarchy messages stuck in the Unreachable Destination Queue. I also have a number of pub stores on servers that show "data not available" under the replication status. I think I need to reboot all servers simultaneously to clear up some routing info that shows up in winroute.exe as not listed in the DS. But i'm not 100% sure this will fix it. I believe there are multiple issues causing me this pain. Has anyone experienced this issue before? Does anyone have any thoughts on how to pin-down the issue and/or troubleshoot/resolve it? Thanks in advanced. David Smith, MCSE, MCTS Exchange 2007
