Resolution
fact
Exchange Migrator 2.x
symptom
Error: 'Unable to expand the folder. The set of folders could not be opened'.
symptom
Unable to open additional mailboxes after the migration in Exchange Migrator.
cause
The path to the additional mailbox was not updated in the current user's MAPI profile registry key. This can be a result of the .tab file containing only the 'host' mailbox and not the 'additional mailbox' as well. This will occur by default if the mailboxes were migrated in different projects.

symptom
Error: 'Unable to expand the folder. The set of folders could not be opened'.
symptom
Unable to open additional mailboxes after the migration in Exchange Migrator.
cause
The path to the additional mailbox was not updated in the current user's MAPI profile registry key. This can be a result of the .tab file containing only the 'host' mailbox and not the 'additional mailbox' as well. This will occur by default if the mailboxes were migrated in different projects.
fix
To resolve this error, please refer to the following:
- Create the .tab file for the project with the 'host' mailbox (e.g. Project1Mappings.tab)
- Create the .tab file for the project with the 'additional mailbox' (e.g. Project2Mappings.tab)
- Using Notepad, copy and paste the entry for the 'additional mailbox' mailbox from the second tab file (from Project2Mappings.tab)
- Paste that line into the .tab file created for the 'host' project (paste/append to Project1Mappings.tab)
- Run EMProfileUpdate pointing to the 'merged' tab file and use the -reprocess switch.
