Add my Domain to 365 without email
Hi, we have a similar problem, but we use Microsoft Teams and we need scheduled meetings. This means we need to assign Exchange Online plans for allowing access to calendar, and this gives us some serious problems, since some emails are routed directly to the cloud mailbox instead of honoring what the MX records says.
Is there a way out of this, like forcing Microsoft to always honor MX records when sending email ?
Thanks.
GianlucaAmatoDid you find a solution?
We have similar situation -- we have a custom domain linked to Office365 but MX records are set to our custom email provider (we do not use Office 365/Exchange for emails).
However Teams meeting invitations (not just Teams, any invitation from Outlook calendar) are sent to Exchange/Outlook accounts (which are not used) instead of our real email accounts respecting MX records.
Thanks.
petrdvorakI made some progress, but I am not satisfied of the results so far.
I tried adding a flow rule in Exchange which forwards all incoming e-mail trough our on-premise SMTP server. This works, but as a side effect, when a meeting is scheduled, the calendar of involved participants is not updated. My guess is that the calendar in Microsoft 365 is updated when an email with the appointment is received, but with the flow rule everything is diverted to our email server.
I would like to try with a flow rule that send everything to our on-premise SMTP server but also keeps the original message in the Exchange mailbox, but I do not know if it is possible.
GianlucaAmato could you write how to create this flow rule? I have simillar problem, we use only external provider for mail boxes, some of the users enable cloudbox and now when someone send invite from teams this mail goes to cloud box not to local mail boxe
From the old Exchange admin center I have created a Connector (mail flow -> connector) with the following configuration:
- Retain internal Exchange email headers
- Only when I have a transport rule set up that redirects messages to this connector
- Add the hostname of my on-premise SMTP server as smart-host
Then, I have added a Mail Flow Rule (mail flow -> rules) with the following configuration:
- Apply rule if: the recipient domain is...... domain I want to redirect on-premise....
- Do the following: Use the following connector .... the connector I have created before
- Choose a mode for this rule: Enforce
