Slow public folder replication between exchange 2007 and 2010
Public folder replication interval is set at 1 minute. We are migrating from exchange 2007 to 2010 and so have users on both environments.
Replication from exchange 2010 to 2007 takes 1 minute.
Replication from exchange 2007 to 2010 takes 15 minutes.
As the messages are delivered to mail enabled public folders in 2007 and then replicated across, this is an issue.
I have used powershell and checked the replicationinterval for all databases is set correctly. I have also reduced the message size limit to 100kb.
Is there any way to speed this up and or monitor what the problem may be?
The servers are at different sites but operate over a high speed WAN link.
Cheers.

Cheers. I have increased the size limit to 2000kb but the same problem exists. The 2007 environment is on SP3 but no rollups have been installed.
The 15 minute replication delay is specific to the 2007 >2010 direction.

As for replication message priority, where is this set? I am struggling to find documentation on where to change this. Cheers.
Hmm, that may have been an Exchange 2003 only setting... as I cannot seem to find any info on the priority setting for 2007 either.
Another thought that came to mind, and it may be completely wrong, but for some reason I thought exchange used some settings stored in AD Sites and Services.... I am pulling from way back, but wasnt the default site replication period every 15 minutes? You mentioned that they were in different sites, it would be worth it to check and test changing the 2007 site to 2010 site AD replication interval....

I am guessing that in 2010 a lot of these settings have been tweaked for better speed, hence why messages coming from there are fast.
