Resource mailboxes

Important Note

  • As part of the move to Exchange Online User, Shared and Resource Mailboxes can take up to 1 hour to provision. Following receipt of the ‘success notification’ the creation process will commence and the mailbox temporarily assigned a ‘MigrationPending’ status. Once complete, the status will update to ‘Active’ confirming a successful mailbox creation and allowing access. You can check the status of the account from the User Management area in the portal.
  • It is important to not make any changes to the newly created account until it is in an ‘Active’ state with a mailbox location of ‘Exchange Online’. Editing any attributes, such as email alias, may disrupt the provisioning process.
  • A monthly summary report is sent to local administrator(s) on shared mailboxes, resource mailboxes and distribution lists which do not have an owner.

A Resource Mailbox (also known as a room or equipment mailbox) is a type of mailbox that can be used for booking meeting rooms or equipment. It is set up like a shared mailbox and has owners and members who have access to it and is an effective way to manage/book meeting rooms or equipment. Once set up, users can then include the meeting room or equipment by adding/inviting the Resource Mailbox to their meeting requests.

As a Resource Mailbox is set up like a shared mailbox, refer to Editing a Shared Mailbox  for more information on how to change any Resource Mailbox attributions following its creation.

The steps to edit, transfer, delete and restore a Resource Mailbox remains the same as for a shared mailbox.

Additional Information:

  • A Resource Mailbox is pre-fixed with an organisation’s shortname
  • It has owners and members
  • It can be set up by Local Administrators
  • Data retention is the same as a personal mailbox as per the Data Retention and Information Management Policy – O365
  • As it is set up like a shared mailbox, a password isn’t required to access this mailbox. Permission can be managed by Local Administrators
  • Standard mailbox size is 50 GB
  • If the mailbox isn’t actively monitored, an out of office message should be added so anyone attempting to send an email to a Resource Mailbox knows not to expect a reply
  • Once created, you can request the NHSmail helpdesk to allocate your device to MS Teams if a Teams room account is required
