I needed the engineer toolset that I had installed on the Orion server for an engineer laptop I did not think I needed it since I installed Orion. After I uninstalled toolset I no longer have email alert option in Orion is this a coincidents or does Orion need toolset for email alerts.
please run a repair on your Orion installation via Add\Remove Software. The reason for this is that ToolSet and Orion are using shared files which might have been deleted with the uninstall of ToolSet.
A repair will bring back the shared files and Orion and Service Pack 5 have to applied after the repair.
Please let us know if this has helped.
