Calendar (2)

Since recently my calendar shows (2) behind it in blue.

Did I somehow copy my calendar? I cannot rename it back either.

The number in blue between parenthesis behind the Calendar folder indicates the amount of unread items in it.

Usually you get an unread item notification when you import a vcs or ical file you got sent as an email attachment or downloaded from a website.

Find the unread items and mark them as read

To find out which items these are and mark them as read, do the following;

  1. Select the Calendar folder containing the unread items.
  2. Type the following search query in the search box; read:no
  3. Double click the item to open it and get it marked as read. If there are many items, you can select them all with CTRL+A and mark them as read with CTRL+ENTER

An alternative way to find the unread items is by using Advanced Find.

  1. Select the Calendar folder containing the unread items.
  2. Open Advanced Find (keyboard shortcut: CTRL+SHIFT+F)
  3. Select the tab: More Choices
  4. Set the option: Only items that are unread
  5. Start the search by pressing the button “Find Now”.
