Hello,
I have installed a Mailstore Gateway on a Windows 10 VM in Azure. This Azure VM should Collect all Incoming (not outgoing) Emails from Journaling in Microsoft Exchange 365.
All incoming Traffic from any Mailserver is working, when we try to send an Email from Microsoft 365 Exchange Server (Any Exchange Server hostet by Microsoft) the Email is not recieved. Is there some rule preventing Microsoft 365 Azure to recieve Emails from Microsoft 365 Exchange?
Pop3 Connection and SMTP Connection from any other source are working just fine, but we need it to work from Exchange 365.
Thank you very much for your support.
