Microsoft Outlook Calendar allows users to create reminders for appointments, schedule meetings, and help in many other ways. Many users often have access to multiple calendars, some of which are shared by managers, colleagues, or clients. Therefore, users need to merge multiple calendars into one so that they can access all their items in one place. That is where the trouble begins because most people do not know a way for merging multiple calendars in Outlook.

But don’t worry! Outlook does provide some good options to merge multiple calendars – one of them is Overlay Mode.

Overlay Mode and Side-by-Side Calendars

Overlay feature was introduced with the release of Outlook 2007, after Outlook 2003 introduced Side-by-Side Calendars.

The Side-by-side feature allows you to select multiple calendars in the Calendar by checking the checkbox at the side of the calendar.

How to implement Overlay Mode in Outlook Calendar?

The Overlay mode allows you to place the Calendars on top of each other so that you can create an aggregated view that will look like a single calendar. You can implement the Overlay feature at the following location:

  • Outlook 2010, Outlook 2013, and Outlook 2016

click View>>Group: Arrangement>>Overlay

With this feature, you can overlay calendars that will allow you to see all calendars at one place, but they will not be combined or merged. So, there are other methods to do that.

It is a two-step process, in which items are exported from one calendar, and then the exported calendar information is imported so that it can be merged with the calendar where you want all items to appear.

  5. Enter a folder location and file name to save the file or click Browse to select a folder and enter the file name. Click Finish.

The above two are the native, yet complicated methods to merge calendars in MS Outlook because sometimes the same calendar gets overlaid each other and create confusion for the users. So, to avoid this confusion, you can opt for the Kernel Merge PST File that is specially designed to merge PST files.
