I am  migrating my public folders from 2007 to 2013. I am received error "MigrationPermanentException: Error: Property expression "CAC Laptops" isn't valid."

I have checked my 2007 server with "Get-PublicFolder -recurse" and that folder is not listed.

How do I find this folder and remove/repair it?

That's probably a value in a different property, like the Alias.

Try listing out all the public folders:

Get-PublicFolder -Identity \ -Recurse
Get-MailPublicFolder

See if you get any "corrupted item" warnings, and then you can drill down on the one that's causing you the issue.

Hi,

Please confirm if this Public Folder is a mail-enabled public folder. Please use Public Folder Management Console to check this public folder.

I think the issue may be caused by the space in the public folder name CAC Laptops. Please change this public folder name to have a try. If this public folder was mail-enabled in Exchange 2007, please try the following steps to have a try:

1. Open ADSIEdit in DC.

2. Click Action > Connect to, select a well known Naming Context: Default naming context > OK.

3. Expand Default naming context. > DC=Domain,DC=com.

4. Click CN=Microsoft Exchange Security Objects.

5. In the reading pane, for each Public Folder with a space, right click on it, select Properties and go to the "mailNickname" attribute and remove the spaces. 

6. Click OK, then run the command on the Exchange 2013 EMS:

Get-PublicFolderMigrationRequest | Resume-PublicFolderMigrationRequest
