However if the PC isn´t domain joined then the ssl certificate used on Exchange aren´t trusted due to the reason that the root isn´t trusted. We might find issues in the Microsoft Remote Connection Analyzer (but that depends on your setup & environment).Ģ.) If you use an internal PKI for the SSL certificates on your Exchange server the root certificates should be automatically pushed to every domain joined PC. As a starting point check the following website. There is an difference how autodiscovery works for Domain joined PCs and non Domain joined PCs. If you have Outlook 2010 (must be fully patched to connect to Exchange 2016 due to mapi over http) you could check the following howto. If that isn´t the case you could try to use a local overwrite from that (see here as starting point), but I would prefer to fix autodiscovery. It's only with the latest builds than an exception is raised.Based on the info you shared there are currently the following reasons possible:ġ.) Make sure that AutoDiscovery is working and that the SCP is configured correctly (see here as starting point).
