How to configure O365 Calendar for On-Prem custom Mail solutions

Occasional Contributor

We have few users that use custom mail solution. Is there a way to configure Teams calendar for these users without moving them to exchange?

Unfortunately no. Teams doesn't actually have a calendar, it leverages Exchange / Exchange Online mailboxes. The closest you could get would be to build a solution to sync entries between an Exchange Online mailbox and your custom solution using Graph API.
