Project Moca is no longer a separate OWA component. Boards created in Moca are now available through the OWA calendar, just like other boards created there. The question is how Microsoft will bring the board view to Outlook desktop. I figure it’s a candidate for OCX and WebView2, just like the Room Finder. Time will tell.
Microsoft is rolling out a new calendar board view for OWA. The new board looks very similar to a Project Moca board, which isn’t surprising because it’s a customized Moca board tailored to focus on the calendar. There’s no news yet when Project Moca might exit its current preview status, but maybe the new view will help by convincing people about the worth of configurable boards.
Project Moca is a new Office 365 personal productivity app which doesn’t have a mobile app. It’s hard to be productive if you can’t be when mobile. Which is why To Do allows people to capture thoughts. A workaround of sorts is available through To Do tasks. Whether this is enough for you to switch to Moca is debatable.
