Why Does my Outlook Calendar Become Large?

Before learning how to reduce the size of my Outlook Calendar, it is important to understand the reasons behind calendar file growth. Some of the common reasons are discussed below:

• Attachments Included in Calendar Appointments: There are times when users attach files such as presentation files, pictures, and documents to their appointments. The inclusion of attachments consumes much storage space.
• Shared Calendar and Sync Data: The repeated sharing of calendars and synchronization of calendar data consumes a lot of storage space and makes the overall Outlook calendar size grow bigger, making people ask questions like how do I reduce the size of my Outlook calendar.
