When migrating folder permissions using On Demand Migration for Email (ODME) the permissions granted on the folder are not migrated and the following is logged:
Source Mailbox: email@example.com Cannot set folder permission 'firstname.lastname@example.org': A UserId was not valid.(A UserId was not valid.)
The users that have permissions to folders within the migrated mailbox are required to be listed within the migration plan.

To migrate folder permissions, create one or several separate plans in which will perform the following:
Note: These plans are run after the contents of the mailbox has been migrated.
