Hi guy,
My customer's AD server contains AD user account with following information:
User logon name : TestUser_za@domain.local
Email Address : TestUser.Jenkis_za@xxx.com
After run the full sync, my customer trying to search "TestUser.Jenkis_za@xxx.com" in people picker but it show error "Sorry, you are not allowed to share this with external users.". however if i try to search "TestUser_za" or "TestUser_za@xxx.com", the people picker will success to resolve the user display name.
In this case, may i say the people picker is search to AD logon account name? is it possible to set the people picker to search email instead of the AD account?
Thanks.
