Script: Get-PFInfo.ps1, Fix-PFSchedule.ps1 & some PF replication troubleshooting info


I’m currently working on a Exchange 2007 to 2010 migrations and the client has about 32K and 600 GB of Public Folders. Getting these to replicate has been a big issue, mainly due to issues with replication not happening as expected. I’ve added the target server as a replica, but folders still didn’t fully replicate.

One of the first things required was a script to get the item and size info for each folder from each server so I could check if items were replicated. After running the script below, which started out just as a long cmdlet, I found many folders didn’t replicate.

After removing, re-adding replicas, doing Update-PublicFolder, and other things they still didn’t replicate. I was finally able to get them to replicate after resetting the UseDatabaseReplicationSchedule AND ReplicationSchedule attributes on the problematic folders using a cmdlet like this:
Get-PublicFolder “\Bad Folder” -ResultSize Unlimited -Recurse | set-publicfolder -UseDatabaseReplicationSchedule $False -ReplicationSchedule “Friday.4:00 PM-Monday.4:00 AM”

I looked into the settings on the Public Folders and most, but not all, were using the default replication scheduled but also had the ReplicationSchedule attribute set. The ones that did have a schedule set should have allowed the folders to replicate. All of the PFs that weren’t replicating were only on once server before the new 2010 ones were added, so replication issues hadn’t come up before.

After doing this the folders finally did replicate, so I suspect the attributes were messed up\corrupted in some way that was preventing Exchange from replicating them. Now that the public folders were adjusted, and probably some others too, to have a custom replication schedule that wasn’t needed anymore I needed to clear out these values. So I wrote Fix-PFSchedule.ps1 to do this, plus a few other things.

The Get-PFInfo.ps1 script is the one I used to get Public Folder data, which writes it to the console and to a CSV file.
