This service pack was replaced by newer updates.
Service pack 1 for Office 2011 for Mac was released in April 2011. In addition to stability, security fixes and performance enhancements, there will be some new features, including improved syncing support. With SP1, users will be able to sync Outlook's calendar, contacts, notes and tasks with any service or device that supports Apple's Sync Services, including the iPhone and iPad.
Among Outlook 2011's new features in SP1:
- Support for Exchange based server-side rules
- Redirect messages to the intended recipient (so replies go to the original sender)
- Resend button
- Edit existing messages
I haven't seen any official word on Read Receipts in SP1, which are missing the RTM. (Update: also missing in Sp1.)
