If you are looking for an easy way to share your Outlook 2007 calendars with others, one solution is to publish your calendar to Microsoft Office Online service.

Share Calendar Online

Open up the calendar in Outlook and Right-click the calendar you want to share then Publish to Internet and Publish to Office Online.

Next you are shown the Office Online Registration overview for an account if you don’t already have one.

Sign in using your Microsoft Live ID.

Accept the terms and conditions of using Office Online.

Choose a user name and finish up the registration.

Now you will get the Publish Calendar to Microsoft Office Online window where you can set up permissions and other settings.

After the calendar is published you can send out invites to let people know the calendar is up. 

It opens up a new email message with the information for the shared calendar and you can add contacts. 

Subscribing to Shared Calendar

Once the contact receives the invite just click on the Subscribe or Preview button under the Share tab.

Click on Yes to verify you want to subscribe to the calendar and its updates.

Click on the advanced button above for advanced configuration options.

If the recipient wants to preview the calendar they are sent to the online calendar.

If you live in Outlook during the business day this is a great way to make sure everyone is on the same page.  This is also a good way to share events with family and friends.
