You can set a priority for a calendar item in Outlook much like you do for email messages, to allow recipients to categorize meetings.
This feature works the same in all modern versions of Microsoft Outlook: 2010, 2013, and 2016.
To set a priority for a meeting invitation in Outlook:
- While in the new invitation, select an item in the Tags group of the Meeting tab of the Ribbon. Choose Private, High Importance, or Low Importance.
To set importance to a calendar item in Outlook:
- Within Calendar view, select the item, and on the Calendar Tools Meeting tab, from the Tags group, select Private, Low Importance, or High Importance.
