Is it possible to view a shared Outlook calendar on iPad/iPhone and/or
Android

Is it possible to get a shared (keyword SHARED) calendar in Outlook to
sync with either an android or ipad/iphone calendar? I am able to get my
primary outlook calendar to sync, but not my shared calendars. I have
googled this topic extensively and from what I've seen posted on various
forums, the answer is a resounding no, but I'm hoping someone might know
of a workaround!
According to Microsoft support, Active Sync does not support shared
calendars. (as per this article:
http://community.office365.com/en-us/forums/158/t/13142.aspx). The
suggested work around is to not use Active Sync and instead set up an IMAP
account. However, my company does not allow IMAP connections, so that's
not an option.
Another possibility is to use a 3rd party tool, such as sync2 to sync to a
gmail account and in turn sync the gmail calendar to the mobile device.
However, that method does not seem to work with shared calendars either.
We are currently using Exchange 2007, but if upgrading to a newer version
could make syncing shared calendars to mobile devices possible, I might be
able to get approval to upgrade.
Any thoughts or ideas or workarounds are welcome.
Auxiliary questions: I am new to working with Exchange. Can anyone explain
why syncing shared calendars with mobile devices is so difficult? Is there
something in the general design that makes it problematic? Is the issue
about security or technical limitations or both (or neither)?
Thank you, Rich
