Microsoft Outlook is a web-based suite of webmail, contacts, tasks, and calendaring services.
Remind creative owners to update deliverables before due dates.
Owners get due date reminder emails, and your project lead sees who has not posted an update by the milestone cutoff.
Keep creative project deadlines current in the team calendar.
Your project list and calendar agree when dates move or plans get canceled. Owners see what changed in a project comment.
