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?

reparing public folder migration to exchange 2013

Ed,

Thanks for you response. when I run the command "Get-MailPublicFolder" i receive about 1000 fo the following errors.  Is this referring to items in each public folder? Also "CAC Laptop" does not show up in that list at all.

1 Piece - Projector  DOMAIN.local/Microsoft Exchange System Objects/1 Piece - Projector
WARNING: Object DOMAIN.local/Microsoft Exchange System Objects/1 Piece - Projector has been corrupted and it is in an inconsistent

WARNING: "1 Piece - Projector" is not valid for Alias. Valid values are: Strings formed with characters from a to z (uppercase or

I found the issue.  Previously, the old admin, created the public folders with spaces in the name and did not change the alias and remove the space.  After changing the Alias it is getting past that one and now I just need to find all the other ones.  To make matters worse they also changed the name without checking all of the property pages so the name does not match the alias on some of them.
