  • Question

  • X = recipient in organisation A

    Y = sender in organisation B

    Z = sender in organisation B

    Y can send email to X through OWA

    Y cannot send email to X through Outlook

    Z can send email to X through Outlook and Owa

    There is some problem with Y. I deleted the profile and re-creted and then Y was able to send emails that evening. But next day again same issue. Is it something to do with contacts / address book?

  • Only this email address and only from this user to this user.

    Y can email X but X cannot email Y through outlook

    X can email any

    Y can receive any

    But when I remove outlook profile and add again, then no problem but problem again in outlook the next day

    Through OWA it is working fine

    Kind regards
