The PR_SERVICE_EXTRA_UIDS property contains a list of MAPIUID structures that identify additional profile sections for the message service.

New profile sections can be created for each message filter. When the information about the message service is to be copied to another profile, it is important to copy the additional profile sections for the filters as well. A service provider that uses additional profile sections can store the MAPIUID structures of those profile sections in PR_SERVICE_EXTRA_UIDS, allowing MAPI to copy the additional message service information.
