OWA and OMA failures on Small Business Server 2003

Microsoft Small Business Server (SBS) 2003 Web site pages, including Outlook Web Access and Outlook Mobile Access, may break if you install the .NET 2.0 Framework. SBS pages and virtual directories only work with .NET version 1.1.

If you need .NET 2.0 for development purposes or to run a specific software program, there is fortunately an easy workaround for this issue:

1. Open the Internet Information Services (IIS) management console.

2. Expand the entry for your SBS server, then Web Sites.

3. Right click on Default Web Sites and select Properties.

4. Under the ASP.NET tab, make sure "ASP.NET version" is set to 1.1. (If it says 1.1.4322, that's OK as well -- just as long as it's the highest available revision of 1.1.) Click OK.

5. Right click on the OWA/OMA virtual directories, select Properties, and
   make sure their ASP.NET settings
   are the same as well.

Note that other issues may be at work, but if you see that ASP.NET is set incorrectly for Exchange Server's automatically created IIS virtual directories, this should clear up the vast majority of existing problems.
