Hello! Is there any plans in future releases to add native Exchange Web Services functionality for syncing of calendars? Currently the only way to sync your calendar and meetings if you use EWS is to use tbsync and excange provider both by the same author (john bieling bless your heart) https://addons.thunderbird.net/en-us/thunderbird/addon/tbsync/ https://addons.thunderbird.net/en-us/thunderbird/addon/eas-4-tbsync/?src=dp-dl-othersby These are 3rd party extensions and therefore if there's a major new version of thunderbird... they're broken for a period of time. I am a linux user, so my only other option is Evolution Mail, which is not bad, but it's nowhere near as good as thunderbird. it does however have an EWS plugin that is natively developed along with it. I know Jason Evangelho works for you now... I know we've got a linux guy in there... (love you man) Hope you do it! it'd basically make it the best email client in the linux community, just sayin'
