sumo83 if it works in OWA, the service is working well.

Maybe delete the offline address books.

its not related to outlook cache etc as this is a behaviour for 3 different users that were testing it... and for myself as well when trying to send an email to "+" address for the very 1st time. Two users tested it in the morning and were send emails. Later that day, it was not working anymore... nor for me when tried it (was not using/testing it before)

 

OWA and also NEW OUTLOOK are giving me the error below:

    Deactivate +-Addressing:
    Set-OrganizationConfig -DisablePlusAddressInRecipients $true
    Wait some hours and activate it again:
    Set-OrganizationConfig -DisablePlusAddressInRecipients $false

      thanks for sharing this... I will try to do it later this week.... However, it looks a bit unreliable to me for now :/. As I had to get the extra emails working ... ehm... earlier today :).... I will go with proper aliases for now. And will maybe play with "plus addressing" another day. 

       

      Thought it would be an easy way to go with... but turned out to be a bit problematic.
