Question

How do I create a Shared Calendar and then assign permissions to the calendar in uConnect.

Overview

These steps are to be performed by your department's administrator.

Answer

Create the mailbox on-premise first

1. Login to https://owa.ucdavis.edu/ecp/ with your administrative account. Note that connections to the on-prem ECP are restricted to campus IP addresses.
2. Navigate to Recipients > Resources/Shared (depending on whether you want to create a resource or shared mailbox)
3. Click the + sign and fill in the required fields. Also be sure to browse to your department OU and place the AD object in the appropriate container.
4. Click save to create the mailbox (at this point you can locate the mailbox in the same ECP and manage delegation if necessary).
5. Use uInform to migrate it to Office 365 (https://admin.uinform.ucdavis.edu/office365move)
6. Wait for the move to finish

To assign permissions:

1. Access the ECP panel - http://outlook.office365.com/ecp  (After move has finished) 
2. Go to Recipients and then resources (or shared or resources, depending on where the object was created)
3. Click to edit the resource you wish to publish the information
4. Go to Mailbox Delegation
5. Add your admin user the Full Access and Send on Behalf (full access may be enough) to this resource
6. Save. Wait 5 to 10 minutes.
7. Access your mailbox via Outlook Web App (assuming your mailbox is in Exchange Online)
8. Click on your name, and select to open another user's mailbox.
9. Type the name of the resource, and select Search. The name will appear. Select and open.
10. It will now open the mailbox for the resource. Click on Calendar.
11. Then right click calendar on the left and select permissions. 
12. Add the group or people you want to have permissions to the calendar.
