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. No additional configuration is required to allow users to use UPN to authenticate when they use 
BlackBerry Connect
. However, if your users' 
BlackBerry Connect
 UPNs don't match their email addresses, you must disable the username validation checking. For instructions, see Allow users to use the UPN to authenticate to Skype for Business Online.
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.
Make sure that the client is running version 2.19 or later.

       tab, in the 
      Exchange User Name
       section, select the 
      UPN
       checkbox.
    2. For 
      BlackBerry Notes
      and 
      BlackBerry Tasks
      , on the 
      Exchange Settings
       tab, in the 
      Exchange User Name
