We have users who share a single email account by using the Additional Email option under their accounts. Now, they want to assign emails to one another using the markers (or flag status) alongside the emails. We noticed that when changing the color of a marker, one Outlook client updated immediately, but another Outlook client did not. It looked like they were both set to "Cached Mode". Is it likely that caching effected the refresh of the client? Would it be better to turn off cached mode if we are using Outlook this way?
