We have 2 domains in our company. I setup a corresponding distribution group for a users email account so he could send an email from either domain address. (example: John.Doe@ficticiousdomain.com is the email account, John.Doe@ficticiousdomain2.com is the corresponding distribution list)
In OWA john.doe is able to send as the corresponding distribution list. However, when trying to do so in outlook 2016 client, user gets a message undeliverable bounce back. Error is [0x80070005-0x0004dc-0x000524]
Any ideas over how to configure the outlook client to make this work?
