OMA Problems   

Hi, I wonder if anyone can help. We have a Front end / back end setup with
OWA working fine with and without forms based authentication. I understand
there is a problem with SSL/Forms based authentication, so to get OMA
working we have disabled this. However we get the following error messages:-

Event Type: Error

I have followed Microsoft's technet Article ID:817379 and I still get this
same error. These errors are the same on both the front end and back end
servers.


Cheers in advance
