Hourly Error in eventlog, Should I worry?

On one of the Team Foundation Server that I maintain at this moment I get the following  event log entry every hour.

An unexpected condition has occurred in a Team Foundation component. The information contained here should be made available to your site administrative staff.

To be sure that this was not degrading my server health I posted a Question in the MSDN Forums, and got picked up by one of the Team members.

It appears that this has to do with an invalid configuration of the Email settings of the server. This particular server is installed without the mail settings configured at all. This leaves the “from” email address for notifications to be empty. Because it is not valid to send mail without the “from” address set, the server generates this error. I could easily fix this problem by following Jeff’s suggested fix.

Under your Team Foundation installation directory, open ServicesWeb.config; locate the value for emailNotificationFromAddress and change it to a valid email address.

This incorrect configuration that caused this event log entry is not something that will affect the server health.
