I was in the process of migrating to Exchange 2013 "Modern Public Folders" for a customer of mine here in Western Australia from an Exchange 2010 SP3 server to Exchange 2013 SP1. After commencing the migration with the New-PublicFolderMigrationRequest cmdlet the migration request shortly after failed.
Looking at the Migration Request Statistics with the following cmdlet it came up with StatusDetail as FailedOther:
Get-PublicFolderMigrationRequest | Get-PublicFolderMigrationRequestStatistics
"Get-PublicFolderMigrationRequest | Get-PublicFolderMigrationRequestStatistics | fl"
The following was logged regarding the error message:
FailureCode: -2146233088
FailureType: DataValidationException
Message: Error: Property expression "Outlook Security Settings" isn't valid. Valid values are: Strings formed with characters from A to Z (uppercase and lowercase), digits from 0 to 9, !, #, $, &, ', *, +, -, /, =, ?, ^, _, `, {, |, } or ~. One or more periods may be embedded in the alias, but each period should be preceded and followed by at least one of the other characters.
In the public folder structure at my customer, there was folder named "Outlook Security Settings" as per the error message.

This folder name or any of the sub items did not appear to breach any of the invalid characters as per the stated error message. Luckily this folder was not required by the business and I simply remove the problematic public folder from the Exchange 2010 server and repeated the move request. After preforming this I was able to successfully complete the public folder migration request.
This is dummy text. It is not meant to be read. Accordingly, it is difficult to figure out when to end it. But then, this is dummy text. It is not meant to be read. Period.
