To share a non-person calendar you are the owner of with others via OWA:
1. Obviously you have to have appropriate permissions for the calendar in question.
2. Log into the OWA with your own credentials (UIUC netID / Active Directory password): https://outlook.office365.com
3. Click on your initials in the upper-right corner of the screen and select ‘Open Another Mailbox’
4. Type in the full address for the account in question. For example: firstname.lastname@example.org. Select ‘Open…’
5. Assuming you have the permission, the account will open. You will now be logged into OWA via the resource account.
6. To share a calendar, select the ‘Calendar’ icon in the lower-left.
7. Click on ‘Share’ near the top of the screen. From here you can Share, Change Sharing Permissions, or Change Publishing Settings (for calendars that have already been shared).
