Summary: Learn how to create an Exchange equipment mailbox, which is a resource mailbox assigned to a resource that isn't location-specific.

In Exchange 2016, an equipment mailbox is a resource mailbox assigned to a resource that's not location specific, such as a portable computer, projector, microphone, or a company car. After an administrator creates an equipment mailbox, users can easily reserve the piece of equipment by including the corresponding equipment mailbox in a meeting request. You can use the Exchange admin center (EAC) and the Exchange Management Shell to create an equipment mailbox or change equipment mailbox properties. For more information, see zz_Recipients (pave over E16 with this).

For information about another type of resource mailbox, a room mailbox, see Create and manage room mailboxes.

  1. In the EAC, navigate to Recipients  > Resources.

  2. To create an equipment mailbox, click New > Equipment mailbox. To create a room mailbox, click New > Room mailbox.

  3. Use the options on the page to specify the settings for the new resource mailbox.

    • * Equipment name   Use this box to type a name for the equipment mailbox. This is the name that's listed in the resource mailbox list in the EAC 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, Capacity, consider summarizing the most important details in the equipment name using a consistent naming convention. Why? So users can easily see the details when they select the equipment from the address book in a meeting request.
    • * Email address   An equipment mailbox has an email address to 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.

  4. When you're finished, click Save to create the equipment mailbox.

Once you’ve created your equipment mailbox, you can edit your equipment mailbox to update info about booking options, MailTips and delegates. Check out the Change equipment mailbox properties section below to change room mailbox properties.

This example creates an equipment mailbox with the following configuration:

  • The equipment mailbox resides on Mailbox Database 1.

  • The equipment's name is MotorVehicle2 and the name will display in the GAL as Motor Vehicle 2.

  • The email address is

  • The mailbox is in the Equipment organizational unit.

  • The Equipment parameter specifies that this mailbox will be created as an equipment mailbox.

New-Mailbox -Database "Mailbox Database 1" -Name MotorVehicle2 -OrganizationalUnit Equipment -DisplayName "Motor Vehicle 2" -Equipment

For detailed syntax and parameter information, see New-Mailbox.

  • * Alias Use this box to change the alias for the equipment mailbox.

  • Hide from address lists   Select this check box to prevent equipment mailbox from appearing in the address book and other address lists that are defined in your Exchange organization. After you select this check box, users can still send booking messages to the equipment mailbox by using the email address.

  • Department   Use this box to specify a department name that the resource is associated with. You can use this property to create recipient conditions for dynamic distribution groups and address lists.

  • Company   Use this box to specify a company that the resource is associated with. Like the Department property, you can use this property to create recipient conditions for dynamic distribution groups and address lists.

  • Address book policy   Use this option to specify an address book policy (ABP) for the resource. ABPs contain a global address list (GAL), an offline address book (OAB), a room list, and a set of address lists. To learn more, see Address book policies in Exchange 2016.

    In the drop-down list, select the policy that you want associated with this mailbox.

  • Custom attributes   This section displays the custom attributes defined for the equipment mailbox. To specify custom attribute values, click Edit Edit icon. You can specify up to 15 custom attributes for the recipient.

Use this section to view or change how the equipment mailbox handles reservation requests and to define who can accept or decline booking requests if it isn’t done automatically.

  • 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 resource. 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 equipment 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 Add icon or Remove Remove icon 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 resource 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 resource. 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 resource. By default, this setting is disabled, so meeting requests are allowed outside the working hours.By default, working hours are 8:00 AM to 5:00 PM Monday through Friday. You can configure the working hours of the equipment 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 the 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 resource 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 resource 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 each instance of the repeating booking request.

There is also a box on this page that you can use to write a message that will be sent to users who send meeting requests to reserve the resource.

Use the Contact Information section to view or change the contact information for the resource. 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 equipment 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.

EUM addresses consist of the extension number and the UM dial plan for the UM-enabled user. Click this button and type the extension number in the Address/Extension box. Then click Browse and select a dial plan for the mailbox.

    • Custom address type   Click this button and type one of the supported non-SMTP email address types in the * Email address box.

      With the exception of X.400 addresses, Exchange doesn't validate custom addresses for correct formatting. You must make sure that the custom address you specify complies with the format requirements for that address type.
    When you add a new email address, you have the option to make it the primary SMTP address.

  • 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 equipment 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 the following sets of cmdlets to view and change equipment mailbox properties:Get-Mailbox and Set-Mailbox cmdlets to view and change general properties and email addresses for equipment 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 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 equipment mailbox properties.

This example changes the display name and primary SMTP address (called the default reply address) for the MotorPool 1 equipment mailbox. The previous reply address is kept as a proxy address.

Set-Mailbox "MotorPool 1" -DisplayName "Motor Pool 1 - Compact" -EmailAddresses,

This example configures equipment mailboxes to allow booking requests to be scheduled only during working hours.

Get-Mailbox -ResultSize unlimited -Filter {(RecipientTypeDetails -eq 'EquipmentMailbox')} | Set-CalendarProcessing -ScheduleOnlyDuringWorkHours $true

This example uses the Get-User cmdlet to find all equipment mailboxes in the Audio Visual department, and then uses the Set-CalendarProcessing cmdlet to send booking requests to a delegate named Ann Beebe to accept or decline.

Get-User -ResultSize unlimited -Filter {(RecipientTypeDetails -eq 'EquipmentMailbox') -and (Department -eq 'Audio Visual')} | Set-CalendarProcessing -AllBookInPolicy $false -AllRequestInPolicy $true -ResourceDelegates "Ann Beebe"

To verify that you’ve successfully changed properties for an equipment mailbox, do the following:

  • In the EAC, select the mailbox and then click Edit Edit icon 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 the Exchange Management Shell, use the Get-Mailbox cmdlet to verify the changes. One advantage of using the Exchange Management Shell is that you can view multiple properties for multiple mailboxes. In the example above where booking requests could be scheduled only during working hours, run the following command to verify the new value.

    Get-Mailbox -ResultSize unlimited -Filter {(RecipientTypeDetails -eq 'EquipmentMailbox')} | Get-CalendarProcessing | fl Identity,ScheduleOnlyDuringWorkHours
