When a user creates subfolders in their inbox (stored locally) and after the migration we try to copy these to the Smartermail account in Outlook 2013 we are not able to do so.
Then we tried to export these folders and mail to a PST file, and then import them from the file.
We just get a message saying:
The service provider does not support it
What are the setting allowing the user to import from a file?
