So, I send this guy the following email:
I am still looking around to see why you are getting this red X when accessing OWA via the IAG. A few articles point to the problem being a missing patch on the Exchange server. Here is a link to the fix I am looking at…
Also, I don’t have any XP machines to test on. Would you have one to try to confirm? I will try secure an XP resource as well.
His response:
fyi firefox works
What the hell? I saw this a lot when I was at IBM. Dealing with the IT world can be so exasperating sometimes…
