Estimated time to complete: 5 minutes.
A room mailbox is a resource mailbox that's assigned to a physical location, such as a conference room, an auditorium, or a training room. After an administrator creates room mailboxes, users can easily reserve rooms by including room mailboxes in meeting requests. For more details, check out Recipients.
For info about another type of resource mailbox, check out Manage equipment mailboxes.
If you're running Exchange 2013 in a hybrid scenario, make sure you create the room mailboxes in the appropriate place. Create your room mailboxes for your on-premises organization on-premises, and room mailboxes for Exchange Online side should be created in the cloud.

Create a room mailbox
Use the Exchange admin center to create a room mailbox
In the Exchange admin center, navigate to Recipients > Resources.
To create a room mailbox, click New > Room mailbox.
Use the options on the page to specify the settings for the new resource mailbox.
* Room name: Use this box to type a name for the room mailbox. This is the name that's listed in the resource mailbox list in the Exchange admin center and in your organization's address book. This name is required and it can't exceed 64 characters.
Although there are other fields that describe the details of the room, for example, Location and Capacity, consider summarizing the most important details in the room name using a consistent naming convention. Why? So users can easily see the details when they select the room from the address book in the meeting request.
* Email address: A room mailbox has an email address so it can receive booking requests. The email address consists of an alias on the left side of the @ symbol, which must be unique in the forest, and your domain name on the right. The email address is required.
Location, Phone, Capacity: You can use these fields to enter details about the room. However, as explained earlier, you can include some or all of this information in the room name so users can see it.
When you're finished, click Save to create the room mailbox.
Once you've created your room mailbox, you can edit your room mailbox to update info about booking options, MailTips and mailbox delegation. Check out the Use the Exchange admin center section below to change room mailbox properties
Use Exchange PowerShell to create a room mailbox
This example creates a room mailbox with the following configuration:
The room mailbox resides on Mailbox Database 1.
The mailbox's name is ConfRoom1. This name will also be used to create the room's email address.
The display name in the Exchange admin center and the address book will be Conference Room 1.
The Room switch specifies that this mailbox will be created as a room mailbox.
New-Mailbox -Database "Mailbox Database 1" -Name ConfRoom1 - -DisplayName "Conference Room 1" -Room
For detailed syntax and parameter information, see New-Mailbox.
How do you know this worked?
You can make sure you've created the room mailbox correctly a couple of different ways:
In the Exchange admin center, navigate to Recipients > Resources. The new room mailbox is displayed in the mailbox list. Under Mailbox Type, the type is Room.
In Exchange PowerShell, run the following command to display information about the new room mailbox.
Get-Mailbox <Name> | Format-List Name,RecipientTypeDetails,PrimarySmtpAddress
Create a room list
If you're planning to have more than a hundred rooms, or already have more than a hundred rooms created, use a room list to help you organize your rooms. If your company has several buildings with rooms that can be booked for meetings, it might help to create room lists for each building. Room lists are specially marked distribution groups that you can use the same way you use distribution groups. However, you can only create room lists using the Exchange Management Shell.
Use Exchange PowerShell to create a room list
This example creates a room list for building 32.
New-DistributionGroup -Name "Building 32 Conference Rooms" -OrganizationalUnit "contoso.com/rooms" -RoomList
Use Exchange PowerShell to add a room to a room list
This example adds confroom3223 to the building 32 room list.
Add-DistributionGroupMember -Identity "Building 32 Conference Rooms" -Member email@example.com
Use Exchange PowerShell to convert a distribution group to a room list
You may already have created distribution groups in the past that contain your conference rooms. You don't need to recreate them; we can convert them quickly into a room list.
This example converts the distribution group, building 34 conference rooms, to a room list.
Set-DistributionGroup -Identity "Building 34 Conference Rooms" -RoomList

Booking requests: Select one of the following options to handle booking requests.
Accept or decline booking requests automatically: A valid meeting request automatically reserves the room. If there's a scheduling conflict with an existing reservation, or if the booking request violates the scheduling limits of the resource, for example, the reservation duration is too long, the meeting request is automatically declined.
Select delegates who can accept or decline booking requests: Resource delegates are responsible for accepting or declining meeting requests that are sent to the room mailbox. If you assign more than one resource delegate, only one of them has to act on a specific meeting request.
Delegates: If you selected the option requiring that booking requests be sent to delegates, the specified delegates are listed. Click Add or Remove to add or remove delegates from this list.
Use the Booking Options section to view or change the settings for the booking policy that defines when the room can be scheduled, how long it can be reserved, and how far in advance it can be reserved.
Allow repeating meetings: This setting allows or prevents repeating meetings for the room. By default, this setting is enabled, so repeating meetings are allowed.
Allow scheduling only during working hours: This setting accepts or declines meeting requests that aren't during the working hours defined for the room. By default, this setting is disabled, so meeting requests are allowed outside the working hours.By default, working hours are 8:00 A.M. to 5:00 P.M. Monday through Friday. You can configure the working hours of the room mailbox in the Appearance section on the Calendar page.
Always decline if the end date is beyond this limit: This setting controls the behavior of repeating meetings that extend beyond the date specified by the maximum booking lead time setting.
If you enable this setting, a repeating booking request is automatically declined if the bookings start on or before the date specified by the value in the Maximum booking lead time box, and they extend beyond the specified date. This is the default setting.
If you disable this setting, a repeating booking request is automatically accepted if booking requests start on or before the date specified by the value in the Maximum booking lead time box, and they extend beyond the specified date. However, the number of bookings is reduced so bookings won't occur after the specified date.
Maximum booking lead time (days): This setting specifies the maximum number of days in advance that the room can be booked. Valid input is an integer between 0 and 1080. The default value is 180 days.
Maximum duration (hours): This setting specifies the maximum duration that the room can be reserved in a booking request. The default value is 24 hours.
For repeating booking requests, the maximum booking duration applies to the length of Exchange admin centerh instance of the repeating booking request.
There's also a box on this page that you can use to write a message that will be sent to users who send booking requests to reserve the room.
Use the Contact Information section to view or change the contact information for the room. The information on this page is displayed in the address book.
You can use the State/Province box to create recipient conditions for dynamic distribution groups, email address policies, or address lists.
Use the Email Address section to view or change the email addresses associated with the room mailbox. This includes the mailbox's primary SMTP address and any associated proxy addresses. The primary SMTP address (also known as the reply address) is displayed in bold text in the address list, with the uppercase SMTP value in the Type column.

Automatically update email addresses based on the email address policy applied to this recipient: Select this check box to have the recipient's email addresses automatically updated based on changes made to email address policies in your organization.
Use the MailTip section to add a MailTip to alert users of potential issues before they send a booking request to the room mailbox. A MailTip is text that's displayed in the InfoBar when this recipient is added to the To, Cc, or Bcc lines of a new email message.
MailTips can include HTML tags, but scripts aren't allowed. The length of a custom MailTip can't exceed 175 displayed characters. HTML tags aren't counted in the limit.
Use Exchange PowerShell to change room mailbox properties
Use the following sets of cmdlets to view and change room mailbox properties: Get-Mailbox and Set-Mailbox cmdlets to view and change general properties and email addresses for room mailboxes. Use the Get-CalendarProcessing and Set-CalendarProcessing cmdlets to view and change delegates and booking options.
Get-User and Set-User: Use these cmdlets to view and set general properties such as location, department, and company names.
Get-Mailbox and Set-Mailbox: Use these cmdlets to view and set mailbox properties, such as email addresses and the mailbox database.
Get-CalendarProcessing and Set-CalendarProcessing Use these cmdlets to view and set booking options and delegates.
For information about these cmdlets, see the following topics:
Here are some examples of using the Exchange Management Shell to change room mailbox properties.
This example changes the display name, the primary SMTP address (called the default reply address), and the room capacity. Also, the previous reply address is kept as a proxy address.
Set-Mailbox "Conf Room 123" -DisplayName "Conf Room 31/123 (12)" -EmailAddresses SMTP:Rm33.firstname.lastname@example.org,smtp:email@example.com -ResourceCapacity 12
This example configures room mailboxes to allow booking requests to be scheduled only during working hours and sets a maximum duration of 9 hours.
Get-Mailbox -ResultSize unlimited -Filter "RecipientTypeDetails -eq 'RoomMailbox'" | Set-CalendarProcessing -ScheduleOnlyDuringWorkHours $true -MaximumDurationInMinutes 540
This example uses the Get-User cmdlet to find all room mailboxes that correspond to private conference rooms, and then uses the Set-CalendarProcessing cmdlet to send booking requests to a delegate named Robin Wood to accept or decline.
Get-User -ResultSize unlimited -Filter "(RecipientTypeDetails -eq 'RoomMailbox') -and (DisplayName -like 'Private*')" | Set-CalendarProcessing -AllBookInPolicy $false -AllRequestInPolicy $true -ResourceDelegates "Robin Wood"
How do you know this worked?
To verify that you've successfully changed properties for a room mailbox, do the following:
In the Exchange admin center, select the mailbox and then click Edit to view the property or feature that you changed. Depending on the property that you changed, it might be displayed in the Details pane for the selected mailbox.
In Exchange PowerShell, use the Get-Mailbox cmdlet to verify the changes. One advantage of using Exchange PowerShell is that you can view multiple properties for multiple mailboxes. In the example above where booking requests could be scheduled only during working hours and have a maximum duration of 9 hours, run the following command to verify the new values.
Get-Mailbox -ResultSize unlimited -Filter "RecipientTypeDetails -eq 'RoomMailbox'" | Get-CalendarProcessing | Format-List Identity,ScheduleOnlyDuringWorkHours,MaximumDurationInMinutes
