One very important aspect of calendar management is the ability to have globally shared calendar information available for publication to the internet or an intranet. To accomplish this, certain requirements must be met prior to publicly or privately  “publishing” shared calendar information. The following are some basics that an Exchange administrator will need to know in order to successfully create publishable calendar content.

With Exchange 2010 SP1, a new virtual directory was added specifically for calendar sharing and the default settings should be set accordingly. To verify the settings prior to proceeding, open an EMS and type:

Get-OwaVirtualDirectory |select name, server, calendar*

This will provide the output verifying that all CAS servers have the CalendarPublishingEnabled flag set to True.

Next, an Internet Calendar Sharing Policy needs to be created:

  1. Open EMC, go to Organization Configuration, Mailbox
  2. Click the Sharing Policies Tab
  3. From the right Actions pane, select “New Sharing Policy…”
  4. The New Sharing Policy Wizard starts. Give the new policy a name, then click the Add button in the Assign Actions section. By default the checkbox to enable the policy is set.
  5. The Add Action to Sharing Policy Domain window pops up
  6. **This is important** -type Anonymous in the top line, and then select “Calendar sharing with free/busy information plus subject, location, and body.

Click Ok, then next, and next on the New Sharing Policy Wizard window. The policy will be created.

Next, open the properties on any global shared calendar  you want to enable publishing on under Recipient Configuration.

Select the Mailbox Setting tab and then Sharing.

Apply the sharing policy that you just created by clicking Browse… and select it from the list.

 

That’s it, you have now created a new internet calendar sharing policy and have assigned it to a global shared calendar.
