They set up a lovely shared calendar for our group to use on my project, but the invite request was cryptic, and the calendar didn't seem to appear on my own OWA login. Eventually I figured out that things are ten times harder with OWA rather than using Outlook directly, and there was an additional problem in that the owner of the calendar had to access it first through OWA to fix a stupid M$ software problem.
Here is something about the invite (to fix this it prescribes steps which involve Outlook directly, no help for me).

This one seems to describe a version of OWA that I don't use, and talks about sharing a calendar of my own:

It turns out that the answer is to use a fancy URL to access the calendar, so that I do it as me but access the other calendar (the calendar has its own email address!)

All of which didn't make sense until I read the following page:

So, I started to play around with putting in other email addresses. I tried my own, I tried my friends'. For my own, it got in, for others I was blocked as expected. It seemed to be a permissions issue to access the group calendar.
This page seemed to hint that there has to be a sysadmin involved:

But my boss came back and said that he'd set it up, and sure enough the screen that came up from the direct URL was different now. Now it said "To view this content, you must first use Outlook Web Access to select the language to display it in." with a single link. When I clicked the link, it came to a very OWA-ish page that demanded that I select a language and a time zone. However, when I did that, I got a different access denied message. Finally I found the below link, which indicated that the solution is for the *owner* to go through the same series of links, set the time zone, and boom it would work for me. And that's exactly what happened to get it all finally working.

Also, my collegues who view the shared calendar with firefox don't get the buttons that allow you to switch between hourly, weekly, and monthly views.
