Product: Microsoft Outlook
Device & OS: not provided
Scenario: Managing daily schedule and availability in Microsoft Outlook or Microsoft 365.
Observed behavior: The calendar displays as 'Busy' all day, every day, and the conflicting calendar entries cannot be selected or changed in either Outlook desktop or Outlook on the web.

Solution 1Recommended

Change the 'Show As' Status to Free for Selectable Items

If you are able to select the busy calendar entries, you can manually change their availability status from Busy to Free.

This is the most direct solution if the calendar entries are editable. By changing the status, the time block will no longer appear unavailable to colleagues using the Scheduling Assistant.

Locate the affected calendar item

Open Microsoft Outlook, navigate to your Calendar view, and find the all-day entry that is marking your schedule as busy.

Open the status menu

Right-click the calendar item to open the context menu.

Change the availability

Hover over the 'Show As' option in the menu, and select 'Free' from the drop-down list.

Change the 'Show As' Status to Free for Selectable Items

Availability Updated: Your calendar will immediately update to show that time slot as free, allowing others to schedule meetings with you.

Solution 2

Investigate Unselectable or Synced Calendar Objects

If items cannot be clicked or modified in Outlook desktop or Outlook on the web, they may be read-only synced items or corrupted objects requiring deeper investigation.

Frequently Asked Questions

Why does my Outlook calendar automatically mark all-day events as busy?

Depending on your Outlook settings or how an event was imported, all-day events may default their 'Show As' status to 'Busy' instead of 'Free'. You can manually adjust this in the event details window when creating or editing the appointment.

Can I hide calendar items that I didn't create?

Yes. If the items belong to a shared calendar, a colleague's calendar, or a holiday calendar, you can simply uncheck that specific calendar in the left navigation pane under 'My Calendars' or 'Shared Calendars' to hide its entries from your primary view.

What should I do if Outlook on the web also won't let me delete an event?

If a calendar item is completely unselectable and cannot be deleted across all platforms (desktop, mobile, and web), it may be a corrupted Exchange server object. You will need to contact your IT administrator, as they can clear the corrupted items using PowerShell or Exchange admin tools.
