Hi All -
I am pretty much an exchange rookie here - but we are moving our on prem non-Exchange mail environment to Office 365 Exchange Online in about 2 weeks.
I just came across a scenario I am looking for guidance on. We have a in-house developed application that handles a majority of our ERP functions (WMS, Accounting, Purchasing, etc). Part of this application generates and emails purchase orders from the person that is doing the purchasing.
I have created an account (enterprise.system) that my developers can use to successfully send email (as enterprise.system). However, a requirement of the system is that it can send Purchase Orders to external vendors as, for example, me. The error they are receiving states that enterprise.system does not have permission to send as the sender. This makes complete sense.
My question is - how is this problem typically solved? I know I can't use direct send because I need to send to external users. Should I / Would you give this account send as permissions on each individual mailbox? Is there a better way? That seems like a little bit of a management nightmare.
Thanks in advance for any replies
