Outlook 2010 and Microsoft Exchange provide the ability to share calendars between users. Follow these instructions to either allow other access to your calendar, or open a calendar you have been given access to.
The easiest way to share your calendar is to open your calendar, click Folder, and click Share Calendar:
Now, complete the Sharing Request and click Send:
To complete the process, click Yes:
Calendar Sharing Request
Here is what you will see if you receive a sharing request:
If you click Allow, you will be asked to confirm the sharing request:
Viewing Another User's Calendar
When your sharing request has been approved, you will receive a notification email like this:
If we click the "Open this Calendar" link, we will see the user's calendar side-by-side with ours:
Shared calendars allow you to create a new appointment in the form of a meeting request, which means that they will have to confirm their attendance.
Shared calendars stay in your Calendars list in a Shared Calendars section. To show or hide a calendar, check or uncheck the appropriate box:
In order to set more specific permissions for your Calendar go to Calendar > Folder > Calendar Properties.
The Calendar Properties will appear, select the Permissions tab.
Here you are able to set very specific Permissions for each user you wish to have access to your Calendar. You are also able to Add-Remove user access from this screen.
To add a user and assign permissions click Add.
You will be presented with the GAL (Global Address List). Select the user you wish to grant access to and click Add.
In this example I will now assign Prospector Pete to have Publishing Editor over my Calendar.
By choosing the Publishing Editor option from the drop down menu you will see some items are automatically selected granting and restricting certain forms of access.
Please note: You do not have to use one of the pre-assigned permission levels; you may assign your own custom level of permissions using the check boxes provided.
