Outlook is one of the most widely used email management applications. It has lots of simple and unique features, which makes it the go-to application for accessing emails and performing many daily tasks. A few of these features are Tasks, Calendar, Archive, Conversations, and a wide range of add-ins.

In addition to other features, we all rely on Reminders in Outlook for many purposes. We are so dependent on an early reminder for a meeting, quick accessibility to the meeting invite through a pop-up feature, clicking on the pop-up to open the invite and then find the link of the Skype meeting, Teams meeting, etc.

All these actions are dependent on the accurate working of the Reminder feature. If there is one miss or glitch anywhere, it can lead us to miss important meetings.
