Minimum interval processing for certain collections


My organization makes heavy use of shared mailboxes. Users that have been migrated to the target Exchange currently see a 3h delay with emails in their shared mailboxes.

To make it easier on the users I wondered if I can have a collection with a minimum interval processing much lower, say 15 or 30 minutes. Just for a hand full of shared mailboxes.

Is that possible?

I found and old and closed topic with a similar question:

Please let me know, this would make things much easier for my users during the migration.

Best regards,
