Not that I’m saying you should run out and patch Exchange.  But if you do on SBS 2011 and if you’ve cleaned up the SP3 folder

Be prepared that it will complain about not finding the media for SP3.

"When attempting to install this update I receive "The feature you are trying to use is on a network resource that is unavailable." When I browse for the resource it is looking for exchangeserver.msi
 
If you removed sp3 folder (cleaned up after yourself) it's looking for that folder location.

“I extracted the Exchange2010-SP3-x64.exe to a temporary directory then could find the exchangeserver.msi and point the dialog at it.   update then completed successfully. Post reboot , all seems Ok.”

    Yep, all my SBS2011 servers did this.

    Hit this one, finished as you described, but then Windows backups started failing. Removal fixed.

    On another server, it was SLOW. Big/fast server, but around 30min into that patch I started investigating, and was alarmed to see Exchange (and many other) services not just stopped but *disabled*. Waited 5-10 more, and I started setting them to manual start (generally safe), and then it finished & reset them back to automatic & started. Phew.
