Any Problems with SP4 for Exchange

The only thing we've had is that you have to be careful and make sure all the Exchange Services are stopped before you run the update. Also make sure if you're using a 3rd party backup utility that they are stopped to, and finally things like NetIQshouldn't be running.

Specifically what we did was set the services to manual. Reboot. Install the SP. Restart the services which the update didn't start. Set the services back to automatic.

I have also heard on a mailins list of a problemwith the interaction between IMC and IS, and that IS can hang.

This is the info..

I want to give you a heads up on 5.5 SP4 which we discovered late
yesterday. In certain conditions, 5.5 SP4 will cause Internet messages to
backup in the Information Store during content conversion. The Information
Store will not shut down and will hang. The conditions exists on Exchange
servers running the IMC with large amounts of inbound Internet mail.
Exchange servers with mailboxes does not appear to be affected but it's too
early to tell. A bug has been filed and a buddy fix has been released to
the companies affected. We are waiting on the results of the buddy fix from
the companies. With this discovery, I recommend you do not install SP4 on
any of your Exchange servers that has an IMC and handles Internet mail until
we get an official released hotfix.

SEVERAL other people, including myself have NOT seen this behavior, so take that bit with a "pinch of salt".

Thanks

we have about 500 users I stoped all services just like the prevoius thread said, but I also did a complete back. To be a little nore carful I took an image of the pc so I could restore it back to original. Just in case. After instaling the service back restored settings from back up and all was well
