I'm looking for some assistance with the permissions needed to allow anonymous/public access to a mailbox in Exchange 2007 (soon to be Exchange 2010). The access needs to be able to view the calendar appointments, but not appointment specifics and must not require a login to see the contents.

I'm aware how to point people to the resouce, but haven't yet found the trick to the permissions. URL for access would be http://exchange.school.edu/owa/[mailbox_SMTP_address]/?cmd=contents&module=calendar.

Anyone accomplished this or have a recommendation?

Exchange 2010 SP1 introduces Internet Calendar Sharing, which essentially allows you to do what you want. The Exchange team posted a very detailed blog post recently about the topic, which I highly recommend you read over.

Basically, Exchange publishes your calendar in iCal format which anybody can subscribe to. The instructions to set it up are in this TechNet article.

  • This is the way to do it. Don't try to hack something together outside of this kind of framework or you're likely to either break OWA or open a massive security hole. – Rob Moir Mar 05 '11 at 22:05
  • Sounfds great, but I'm really looking for a solution now rather than this fall when we migrate to 2010. I have a faculty (and they run the place) who is having new issues with syncing their calendar with 3rd party tools and would rather make our existing tools (OWA/Exchange) work rather than make something like Tungle or Google Calendar Sync work. – edusysadmin Mar 06 '11 at 03:44
  • @edusysadmin - sorry I don't know anything that does what you want pre Exchange 2010 SP1. I guess you could roll something with EWS, but that would require programming knowledge and the time to create such an application. – Ben Pilbrow Mar 06 '11 at 11:05
