Planner notification email with on prem exchange(2016) (with hybrid configuratio)
we have on prem exchange (2016) with hybrid configuration. We have successfully configured mailflow between O365 and On prem exchange. But our planner task notifications emails are not working for our users which is a huge problem because we have project going live next month and we wanted them to work . I understand officially planner is not supported with on prem exchange as per MS article but is there any other workaround we can use?
thank you in advance
