We have on-prem Dynamics CRM 2011 and Exchange 2010. We're migrating to Exchange 2016 but need to make sure that our existing CRM 2011 is not affected.
Can anyone confirm compatibility of CRM 2011 E-mail Router with Exchange 2016?
Official Microsoft Dynamics CRM 2011 is not supported with Exchange 2016 according to the Compatibility with Microsoft Dynamics CRM 2011. So I would upgrade that as well to ensure its up to date and if you run into any issues where you need the help from Microsoft you could get some help here.
