wwfuk-ptobias Posted July 20, 2017 Share Posted July 20, 2017 Hello, we currently have ServiceManager configured to use Outbound mail via a mailbox that in Exchange on-premise (Exchange 2010). We had to setup some firewall rules and some SMTP relay connectors to get this to work. We are planning to migrate the mailbox account to Office 365 (Exchange 2016 online) and would like to know if anyone has got this working and what configuration is needed. Not sure if a SMTP connector will need to be created with the Hornbill IP that emails will originate from? Would be much appreciated if someone could advise. Many thanks, Pete.

Hornbill Staff DR Posted July 21, 2017 Share Posted July 21, 2017 Hi Ptobias,  thanks for your post. Generally speaking, you can approach office 365 using similar principles to an on-premise mail exchange. It is still a mail exchange, its just now hosted in the cloud. The first step in the configuration is to "point" Hornbill to office 365 rather than your on-premise mail exchange. This means updating the SMART HOST configuration via Hornbill Administration. Just like in an on-prem situation, office 365 will need to know what to do with the email that it receives from Hornbill and therefore you will need to configure office 365 to allow the relaying of messages from Hornbill onto the intended recipient. Finally, its unlikely that there will be any firewall considerations, as we are considering cloud-to-cloud communication. I hope that helps. Dan Link to comment Share on other sites More sharing options...
Martyn Houghton Posted July 24, 2017 Share Posted July 24, 2017 @wwfuk-ptobias Pete Just to advise that we have one of our mailboxes linked to Office365 from our instance and apart from the recent Bare Line Feeds issue which has now been resolved, not had an issue. Login ID is your full Office 365 email address. Cheers Martyn Link to comment Share on other sites More sharing options...

Gary@ADL Posted April 17, 2021 Share Posted April 17, 2021 hey guys - sorry to drag this thread back from the dead but we are trying to do the same thing currently (migrate our mailbox to 365). ive followed the above the above instructions which seemed to have worked, but its the configuration on the 365 end i am struggling with. the error i am getting with the hornbill config checker suggests i need to need give my mailbox permission to send on behalf of another user. to get round this (because we cant create a user for do-not-reply@live.hornbill.com i dont think), ive made a contact, and set the smtp address as do-not-reply@live.hornbill.com, then set this contact to have "send on behalf of" permissions for my hornbill 365 mailbox, but im still getting the same error? does anyone have any ideas? thanks Link to comment Share on other sites More sharing options...
Gary@ADL Posted April 18, 2021 Share Posted April 18, 2021 hey guys - we got this done in the end - we didnt even have to configure our outbound mail pointer, we just pointed our mailbox at the 365 account and it all seemed to work Link to comment Share on other sites More sharing options...
