I have changed my email server (System/Email) to use 3cx SMTP. For some reason the system keeps updating this setting to use my corporate address. We use 365 Integration, and I am the system owner. How do I fix this?
so when you select 3CX's SMTP server and hit apply, youre saying that emails are still sent from your 365? They should come from a noreply@3cx address.
When I select 3cx SMTP Server and apply, emails are sent from noreply correctly. Then when I check back a day or so later they are sending from M365 again. I am trying to figure out what is triggering the change.
Ah ok. I’ve seen this happen on initial setup of 365 with the wizard but I doubt you’re doing that everyday manually.
What options have you got selected to sync with 365?
You could always create a shared mailbox for 3cxnotifications@ in your 365 and then use the UPN from this account to send email. It’s what I do. Doesn’t need a license
