External Application send email via Outlook 2013

    Question

  • Hi,

    After the upgrade, Outlook 2013 users are complaining that when they send email via another program, the LegacyExchangeDN is showing up when the sender view the email within their SENT item folder.

    What could be reason that senders seeing this LegacyExchangeDN attribute in their SENT item folder?

    thank you


    Best Regards,

  • Hi,

    Does the same issue persists if we view the sent items from within OWA?

    >>could this be application integrated relation issue?

    >>or Outlook 2013 issue? Because this does not happen on Outlook 2007 or 2010.

    To identify whether this is the application integrated relation issue or Outlook 2013 issue, we may try to send emails to the same recipients directly within Outlook 2013 to see the result. If the same issue continues, it means it's Outlook 2013 related issue.

    In addition, since this issue only happens to Outlook 2013 users, we may try to contact the support of the integrated program and confirm whether there is any compatibility issue between the program and Outlook 2013.

    Regards,

    Steve Fan

  • Thank you for the update.

    >>Could this mean that it most likely not Outlook 2013 / our Exchange issue?

    It's uncertain currently.  Since there is no issue when send email directly via Outlook, it's certain that the issue lies with the 3rd-party program itself or lies in the process how the 3rd-party program send emails via Outlook.

    May I know do you have cached Exchange mode enabled? If so, we may try to switch to online Exchange mode and then see if this issue continues.

    In addition, is it possible to know how the program read recipients' email address from Outlook? From Contacts folder, GAL or Auto-Complete cache?

  • Hi Steve,

    Thanks for following up.

    We are running Cached Mode.

    1. When switch to Online Exchange Mode, the external application failed to launch.

    2. Since external application failed to launch, most likely indicating it read recipient's email address from Auto-complete cache?

  • Thank you for the update.

    It looks like the application only works with cached Exchange mode. Thus, it could be the Auto-Complete cache or the Offline Address Book. Have you tried deleting the Offline Address Book file (.oab) and then sync a fresh one from the server to see the result? For your convenience, the OAB files are by default stored in the following path:

    drive:\Users\%username%\AppData\Local\Microsoft\Outlook\Offline Address Books

  • It seems to me it's most like an issue with the mentioned third party application.

    Hi, if you rely heavily on the 3rd-party program to send emails, I'm afraid we have to either wait for a newer version of the program to fix the issue or downgrade to Outlook 2010 to make it work.
