Thanks  MrCharlesJenkins . I am now able to send emails using the alias. However, when the emails are received, they still display the actual email ID instead of the alias. How can we ensure that the recipient sees the alias as the ‘From’ address?

Also, is it possible to add or assign delegate permissions to the actual mailbox using the alias?

Hi Michealmary, 

did you test by sending email as alias to an external recipient?

    Hi Victorvanidze,

                        I attempted to send emails to an external recipient using the alias email address. The alias email ID is displayed correctly, but the name appears as "nucleusmailer" instead of the alias display name. I’ve attached a screenshot for reference.

    However, when sending emails internally, neither the alias email ID nor the alias display name is shown. I need the alias email address and display name to appear for internal emails as well.

    Please help me to resolve this issue.

     

     

    Thanks

    Mary
