Hey Daniel Schmidt, Thanks for the feedback! We definitively understand the gaps and are working on a number of these.
- Favorite People with notifications (aka VIP notifications) is targeted to begin rollout in May for Office 365 accounts leveraging the native Microsoft sync technology.
- Our calendaring capabilities are unparalleled when compared to the native client (shared/delegate calendar support, attendee status, Skype (and later this month Teams support), etc.). We have a few videos (more to come) that highlight our scenarios and capabilities at http://aka.ms/omvideos.
- Our strategic direction for notes and tasks is OneNote and To-Do services/apps. OneNote recently launched Sticky Notes support which works with notes in the Exchange mailbox. To-Do synchronizes tasks with Exchange.
- Shared mailbox support is on our roadmap and will begin rolling out later this quarter for Office 365 accounts leveraging the native Microsoft sync technology.
As always, you can stay up to date on our planned features via our roadmap at http://aka.ms/m365roadmap.
