Polling not working when sending from on-prem to Exchange Online...

[Matt Ellis]

Does anyone have any idea why emails with polls sent from on-prem to users on Exchange Online don't appear?We're using Exchange 2013 CU10 hybrid currently. No other issues with mail flow. Internal OOF is working okay.

Thanks...

Matt

Sorry, should have been a bit clearer. The emails arrive but without the poll question in the email.
