Allow users to use the UPN to authenticate to
Microsoft Exchange Online

If users in your environment are configured with UPNs that are different from their email address, complete the following steps for the
BlackBerry Work
,
BlackBerry Notes
, and
BlackBerry Tasks
 client.
By default,
BlackBerry UEM
 creates implicit UPNs for
BlackBerry Dynamics
 apps (for example,
samAccountName
@
Internal_domain_name
) and uses the implicit UPN to authenticate to
Microsoft Exchange Online
. Consider the following scenario for userA using
BlackBerry Work
 in your environment:
  • BlackBerry UEM
     creates an implicit UPN: userA@example.internaldomain.com
  • The
    Active Directory
     has the following information for userA and environment:
    • Domain sign in is example.internal.com
    • SamAccountName is userA
    • UserA email address format is
      firstname
      .
      lastname
      @example.com
    • UserA's UPN (explicit UPN) is userA@example.com
In this scenario, the external email domain and the internal domain are different. As a result, the explicit UPN in the
Active Directory
 and the implicit UPN  created by
BlackBerry UEM
 don't match and authentication fails. For more information, visit support.blackberry.com/community to read article 58448.
