PowerShell | Help & additional information

Running PowerShell commands in Office 365 based environment
To be able to run the PowerShell commands specified in the current article, you will need to create a remote PowerShell with Azure Active Directory or Exchange Online. In case that you need help with the process of creating a Remote PowerShell session, you can use the links on the bottom of the Article.

Resource Mailbox is a special type or a Mailbox that uses for the management of Meeting Rooms and Equipment.
The Resource Mailbox doesn’t require a license.
Management of Resource Mailbox could implement by using one of the following options:

  1. Self-management – the Resource Mailbox will be configured for automation of accepting meeting requests (or decline meeting request if a previous meeting request already set).
  2. Resource Mailbox Delegate – The delegate is the person that will accept the meeting requests and approve or decline the meeting requests.

The term “resource Mailbox” includes two types of Mailboxes – Room Mailbox and Equipment Mailbox.

There is a small difference between the two types of the resource mailbox but the use, and the purpose is quite similar (most of the examples will relate to room Mailbox).

A little confession – I must admit that it wasn’t easy to give up the strong need for naming these articles: Get a Room!
(But I know that this is a “serious” WebSite and, for this reason, I use a formal name).

    We create a Security Group and assign that group to be the resource Delegate, this allows the group owner to select the delegates. The group has “FullAccess” to the resource; the group has “Reviewer” access to the /Calendar:
    Add-MailboxPermission -Identity Resource_Name
    -AccessRights FullAccess

    -User Security_Group

    Add-MailboxFolderPermission -Identity Resource_Name:Calendar
    -AccessRights Reviewer

    -User Security_Group

    The use of security groups gives greater flexibility for resource management. For some resources, our default of “Reviewer” may be insufficient; the delegates may change this via Outlook (or contact us).

    As far as I know , the issue of “converting an existing Distribution Group to a security group” is not enabled in office 365 ( Exchange online)
    The only option to set Distribution Group also as a “Security Group” is when you create a new Distribution Group.
    To set a Distribution Group also as a security group you can use one of the following options:
    1. Exchange online Web Interface
    when you create a new Distribution Group chooses the check box: “Make this group a security group”
    2. PowerShell
    For example: New-DistributionGroup -Name “Office Users” -Type “Security”
    If you want to be sure that this option is not enabled, you can try to use the following PowerShell command
    Set-DistributionGroup -name “Office Users” -Type “Security”
    You will get the following error
    “A parameter cannot be found that matches parameter name ‘Type’”

    Don’t you have to set the send and receive quota to 250MB because that is a service limit to have a free conference room right?

    Don’t you have to set the sendrecive quota to 250mb on the room mailbox to ensure you don’t go over the free service limit restriction?

    I need to rename a room resource. How can I do that without deleting all existing reservation.

    • Doreen

      The Room can be renamed and the bookings will stay in place, but the organizers calendar will not update nor will attendee calendars be updated, so you need to warn the organizer that the room is renamed, then he must update the room in his invite and send it to the attndees. Pretty Painful.

    You can rename the room, and the bookings will remain in place in the room calendar, but the new name is NOT reflected in the organizers calendar nor the Attendee calendar. So you must manually warn the organizer that the change has occurred and that they should update the room name in the booking and send the update a to the attendees.

    Hi, these are a great collection of management tips.

    Is there a way I can perform this one in bulk for all room resources?

    I can’t find a way to pipe a query for this part of the script (<Room:\Calendar> )

    Set-MailBoxFolderPermission -AccessRights LimitedDetails  <Room:\Calendar> -User default

     

    Thanks,

    Corey

    I am reviewing the output of me current resource rooms to the ones I just created and I am finding that I am not able to add the group while in the GUI, thus the reason I am here collecting PS commands.  However what I am finding is that  I need to change several additional areas:

    ScheduleOnlyDuringWorkingHours: False  to True

    AllBookInPolicy: True to False

    AllRequestinPolicy: False to True

    AddAdditionalResponse: False to True

    I am looking at locking down some resource calendars such that only 1 of our 365 domains can book it. Can i do this without maintaining a security group for all users of that particular domain? I want just some rooms to be bookable by one domain, others by everyone. All domains are in our 365 tenant of course.
