Issue

If you are using Events design element in the combination of any of the following connections: 

• My Events (Outlook)
• Shared Events (Outlook)
• Group Events (Outlook)

In some situations, after you click Connect in the Connect tab if you move to the Items Tab, the Recurring and All Day properties will be missing from the associated drop-down list.

However, these two properties will remain mapped even if they don't appear in the associated drop-down list from the right.

Workaround

Step 1: Close the Page Builder and Open the Element Settings Again

Step 2: Go to the Items Tab and check the Mappings
