Exchange 2016 - Outlook 2016 - 550 5.1.0 RESOLVER.ADR.InvalidInSmtp RRS feed

  • Question

  • Hello, 

    I have issue when sending email to some addresses. Server respond with:

    Remote Server returned '550 5.1.0 RESOLVER.ADR.InvalidInSmtp; encapsulated INVALID address inside an SMTP address (IMCEAINVALID-)'

    My enviroment: Exchange 2016, Outlook 2016

    I have already researched something and came to this post.
    https://social.technet.microsoft.com/Forums/office/en-US/993bb2ea-badc-4392-95c5-d95b10d62855/exchange-2013-outlook-2010-550-510-resolveradrinvalidinsmtp-encapsulated-invalid-address?forum=exchangesvrclients

    I have emptied the address cache as described. Furthermore, I also disabled the cache. All that has not helped.

    The process: The user creates an offer from our ERP. This is then passed to Outlook (I guess about a mailto link). The user then saves this mail as a draft. If he now checked and send it, the mail comes back with the error message.

    I also noticed that the email address is supplemented with our local domain.

    Any suggestion, how to resolve this issue?

    Thx.
