Word is out that today Exchange 2007 SP3 was released. It’s “compatible” with SBS 2008, however you really need to read this KB before you install it so that you can ensure you don’t have problems. Basically if you have ForeFront Security for Exchange installed, you need to disable it for the duration of the service pack – the KB includes instructions on how to do this. Also if you HAVE NOT RUN the Internet wizards on SBS 2008 then after the service pack, you WILL HAVE PROBLEMS. Below (from the KB) are the instructions on how to fix it.
Here are the known issues from the KB article above
Known issues that may occur after you install Exchange Server 2007 SP3
After you install Exchange Server 2007 SP3, you may be unable to access the following Web sites:
Note This issue occurs only if the Internet Address Management wizard has not already been run on the computer.
To resolve this issue, edit the bindings for the SBS Web Applications site to select the correct certificate. To do this, follow these steps:
- Open Internet Information Services (IIS) Manager.
- Expand server_name.
Note The server_name placeholder represents the name of the server.
- Expand Web Sites.
- Right-click SBS Web Applications, and then click Edit Bindings.
- Click HTTPs port 443, and then click Edit.
- Under SSL certificate, select the Sites certificate.
For those of you that recall the issues with Exchange 2007 SP2 on SBS servers, you will recall that we had to wait for an additional SBS patch before installing Exchange 2007 SP2. I have it on good authority that this is included in Exchange 2007 SP3 and therefore we can reliably install SP3 on top of SBS 2008 provided we’ve already run the various SBS 2008 wizards as mentioned above.
Have I tried it yet – No. I’ll be leaving it till the weekend when I can plan some downtime, do my backups etc.
