Update Rollup 9 for Exchange 2007 Service Pack 3 is now available for direct download. As it also contains a security update, it’s directly being offered via Microsoft Update as well.
The other fix that it contains is for the following issue:
- When you send a corrupted meeting request to another user, Microsoft Exchange Transport service (EdgeTransport.exe) crashes. The expected behavior is that the Exchange Transport service handles the problem and continues to run.
