Exchange service restarts

Hi

Today, we had to restart the System Attendant service on Exchange 2007 Mailbox servers to fix an issue. Which brings the question, apart from the Information Store, are there any MS Exchange services on a 2007 box (mailbox, Hub, CAS) that would bring about an outage to users if I restarted the service? Sys Attendant didn't seem to cause a problem.

Sys Attendant stopping will prevent address book lookups, moving mailboxes, creating users. It is several services that proxy AD requests, among other things...

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

The only thing that will cause a client to actually notice is the information store.

The others will not cause any errors at client side.  Not so they would notice anyway.

Hi All

Yes, as demazter says, I should hve clarified and said service restarts that clients would actually notice!

Just in case people want to amend their responses/ answers :)

Transport will stop mail going in and out, it will simply be queued and the client won't notice.

This is what the System Attendent service does: http://msexchangeteam.com/archive/2005/06/09/406137.aspx

And to be honest, it's so quick nobody would notice anyway!
