The Exchange Team announced that they have re-released Rollup 3 for Exchange 2010 SP1. This V3 release fixes the following issues which the original rollup introduced;
- Duplicate messages in the Sent Items folder on Blackberry devices.
- Email delivery delay for Outlook 2007 and Outlook 2010 users.
In case you had not yet removed the V1 release; you can apply the V3 release like any other rollup. The same is true when you had already removed the V1 release or hadn’t applied it yet.
