When I looked into this a few years ago, the only option I could find was to send the outsider a 'snap shot' ‘snap shot’ of your calendar (unless you got fancy and started linking your Exchange calendar with a Google calendar). With the 'snap shot'‘snap shot’, it meant that whatever was listed in your calendar when you sent it was what they could see – no later updates or additions, unless you sent them another 'snap shot'‘snap shot’.
I had someone recently ask again about being able to do this, and found that there is a way for you to publish your real-time calendar through Outlook or OWA (exchange.cornell.edu), so I thought I'd I’d share since it could be very beneficial to those of you that work with outside organizations.
Here's Here’s how: http://help.outlook.com/en-US/140/ms.exch.ecp.CalendarPublishing.aspx

- You can select how much detail can be viewed on your published calendar: Availability Only, Limited Details or Full Details
(Even if you select Full Details, those appointments set as 'private' ‘private’ will not be shared.) - You can restrict how many months before and after today's today’s date to publish.
- You have two options for access: Restricted or Public.
- Restricted means that the only way a person would be able to view your calendar is if they knew the web link to your published calendar.
- Public allows anyone to search for your calendar on the Internet (I would only recommend this for a group account calendar where you have only public events you wish to advertise)
Click here for an example of a published Exchange calendar - You will have two web links that you can copy and paste to send to the outsider. (See photo)
- 'Link for subscribing...' ‘Link for subscribing…’ is a ics file which means the person will be able to view your calendar in Outlook.
- 'Link ‘Link for viewing..' ’ is a html web address for the person to view your calendar in their web browser (see example link above)
Keep in mind that after the e-mail/calendar switch to Office365 early next year, the link to your published calendar will change.
