From the Help Desk file…
Reported Issue: Users report Outlook Web Access (OWA) ‘looks funny’ or ‘messed up’ and is missing the graphics. The main body says “Loading…”.
There is also no screen color, just a bunch of hyperlinked boxes with red X’s.
System: Windows Server 2003, Exchange Server 2003 with Service Pack 2
Details: Here is a screen shot of the error condition
Dead Ends:
- Outlook Mobile Access is working fine
- Event logs aren’t throwing any errors
- ASP version is good
- Restarting application pool didn’t help
- Restarting IIS didn’t fix it either
Diagnosis: This was a permission issue. SSL wasn’t enabled on OWA
Resolution:
- Open IIS Manager
- Navigate to Server Name / Web Sites / Default Web Site / right-click Exchange / choose Properties.
- Click on Directory Security, and in the Secure communications box, click Edit.
- In the Secure Communications window, make sure Require secure channel (SSL) and Require 128-bit encryption are checked.
- Hit OK, OK and Restart IIS
If those boxes are already checked, take a look at the NTFS permissions on the hard drive for the IIS folder. And if you do have to eventually reinstall Outlook Web Access, be sure to check out Henrik Walther’s article, “Fixing a Damaged or Incorrectly Configured OWA 2003 Installation“
