Dear SmarterMail Users,

I would like to explore possible solutions for integrating SmarterMail Enterprise with Office 365 in a hybrid setup.

Currently, my company uses SmarterMail Enterprise for approximately 1,500 email accounts, while around 300 users are on Office 365 Business Standard. However, we frequently face an issue where emails sent automatically from SharePoint, Microsoft Teams (such as calendar invitations), and other Office 365 collaboration tools are being routed to Office 365 mailboxes instead of SmarterMail mailboxes.

I would appreciate any insights or recommendations on how to configure a hybrid environment that allows seamless coexistence between both email systems. Additionally, does SmarterMail Enterprise or Office 365 support such a hybrid setup natively?

Looking forward to your guidance.
