I have a default reminder time set for calendar events, but I don't get an alert reminding me of the meeting. It shows up in the list of reminders in Office Reminder app, but nothing pops up to alert me. Unlike in the Windows version I used previously. 

The mailbox was converted (or transferred) from a Windows environment. I use Outlook in a corporate environment. Our techs say that functionality doesn't exist for Mac, but I don't believe it.

Thanks!
