I have keep getting the error , "certificate domain name does not match outlook.com. Outlook.com is my exchange server, i think. It always works when i enter it as the server with the default email app on android. I can send emails though. configuring exchange for k9 is such a pain! Anyone know what this means? Main reason I want to use k9 is so i can save attachements...so if anyone knows a better email app that supports exchange (not touchdown) or a way to download attachments with default email app.. that would be nice.
