Make guest users visible in GAL

Make guest users visible in the Global Address List

  • As a part of my previous work was added as a guest user in tenant
  • The user is hidden from address list in tenant (this is by design)

  • Attempting to add as a contact in
  • We will not be able to add to as the SMTP is already in use by the guest mail user

  • To make the guest user visible in GAL we would run a PowerShell command in the tenant :
    get-user | Set-MailUser -HiddenFromAddressListsEnabled $false

  • NOTE: we cannot have a MailUser and a Guest User with the same SMTP
