As for your feedback concerning time-blocking, we appreciate your comments and understand the roadblock you’re facing at this time regarding shared Outlook calendars… Can I ask if this feature request is along the lines of what you’re hoping for? With the addition of an end time in the date column, this opens opportunity for time-blocking within the native calendar! If this is the case, it’s on our roadmap! Stay tuned
