How to Merge Calendar Appointments in Microsoft Outlook

When you manage multiple calendars in Outlook -- for example, one for a sports team, one at work and another for your personal schedule -- you may find it more efficient to merge the data so it is organized in one, centralized location. While Microsoft Outlook does not feature an automated merging tool, you can export the data from one calendar and import it -- with differentiating color labels -- into another.

With Outlook open, click the "File" tab and then "Open & Export," "Import/Export" and then "Export to a File." Select "Outlook Data File (.pst)" and determine a save location for the final file. Allow Outlook to load a list of your managed calendars and click the name of the calendar you would like to export.

From the "File" tab, select "Open & Export" and then "Import/Export." After selecting "Import From Another Program or File," select "Outlook Data File (.pst)" and browse to the newly exported data where you just saved it on your computer. At this point, determine how you'd like the software to handle duplicates -- by replacing or ignoring them, for example. Select "Calendar" for your import source and then click "Finish" to complete the import.
