Microsoft has released Service Pack 3 for Exchange Server 2010.
This is a significant release that delivers some key functionality to customers such as support for Windows Server 2012, support for co-existence with Exchange Server 2013 CU1, and general bug fixes and security updates.
This seemed to be a major issue to me until I performed the upgrade in my test lab.
The statement above is correct for standalone mailbox servers, which is expected.
The end of support for SP2 simply means that those computers will not receive the most current security fixes from Microsoft’s update website or the automated updates.
Since it’s very important to keep your Windows up to date, how can you find out if your machine needs to update to SP3?
Just as my fellow author, Amit, had warned you, Microsoft has ended support for PCs running Windows XP Service Pack 2 (SP2).
According to figures I’ve seen at Information Week, as many as 45% of Windows XP machines will need to update to SP3 in order to stay secure.
…During the upgrade, the database is dismounted, and all mailboxes in that database are taken offline.
If you are planning to upgrade your Exchange 2010 servers to SP3 you should be aware that there is an Active Directory schema update involved.
If that is a concern for your environment, but you still want the bug fixes and security updates, you might consider sticking with Service Pack 2 and applying Update Rollup 6 instead.
If you are running a PC that has not been updated yet, there’s no need to panic.
Computers running SP2 will continue to work as usual.
