1. Log into the Office 365 Exchange Admin Center: http://mail.office365.com/ecp
2. In the Dashboard, select 'Resources' under 'Recipients'.
3. Click on the + symbol, and select the type of resource (in this example it is 'Room').
4. Fill out the details and save.
5. Now that the Room has been created, it can be added to Outlook using this process: 'Office 365 Outlook 2013 Adding Rooms'.
Providing a single user with Full Access from the Office 365 Admin Center.
By default, a Room resource only allows Free/Busy calendar information to be seen. Delegating Full Access from the Exchange Admin Center only allows the specified user/s to view and edit the content from Room calendar in Outlook. However, you cannot change permissions.
1. Double-click one entry or select the entry and click on the edit icon.
2. Go to 'Mailbox Delegation' and add accounts requiring view access to Full Access
Changing permissions for a resource, e.g. Room.
Some usage cases may require all staff to view the content of the Room calendar or make changes. The current process used to get this to work involves giving an account the correct permissions to the Room in PowerShell, in order for the account holder to configure permissions of the Room in Outlook. Simply changing the default permissions in PowerShell does not appear to propagate to the accounts in Outlook 2013.
In this example, Meeting Room 1 is the 'account' firstname.lastname@example.org, and rights are given to the user account email@example.com. We will assign Owner permissions so that firstname.lastname@example.org will then be able to change the permissions as required.
1. Connect to PowerShell for the required tenant using the administrator account.
2. Check permissions:
3. Set permissions:
Add-MailboxFolder email@example.com -User firstname.lastname@example.org -AccessRights Owner
4. In Outlook, the user will then have rights to make changes to permissions.
