How to Fix Outlook Calendar Displaying Only a Small Portion of Another Calendar
Product
Microsoft Outlook
Device & OS
not provided
Scenario
Opening another person's calendar alongside a personal calendar using Outlook's split view functionality.
Observed behavior
Only a small portion of the second calendar is rendered on the screen. The issue temporarily resolves when switching between calendar views or reopening the application, specifically in Outlook version 2407 (build 17830.20056).
Before you start

Check your exact Outlook version by navigating to File > Office Account to confirm if you are on the affected build (2407) before applying these workarounds.

Solution 1Recommended

Apply the Calendar View Workaround

Switching between different calendar views forces the Outlook interface to refresh, which temporarily resolves the display bug.

Since this is a known rendering bug in specific builds of Outlook, forcing a user interface refresh is the quickest way to regain full visibility of the shared calendar.

1
Open Split View

Launch Outlook, navigate to the Calendar section, and select another person's calendar to open it in split view alongside yours.

2
Change the View

Click on the 'View' tab located in the top ribbon menu.

3
Toggle View Options

Switch the view from 'Work Week' to 'Month' view, and then immediately switch it back to your preferred layout. The calendar should now render fully.

Temporary Solution: This workaround resets when Outlook is closed. You may need to repeat these steps upon restarting the application until Microsoft releases a patch.

Frequently Asked Questions

Why does my Outlook calendar only show half the screen in split view?

This is caused by a UI rendering bug present in specific builds of Microsoft Outlook (such as version 2407). The application struggles to properly allocate and refresh the screen space when loading a second calendar in split view.

How do I report the calendar display issue to Microsoft?

Open Outlook, click on the 'Help' tab in the top ribbon, and select 'Feedback'. Choose 'Report a Problem' and include your exact Outlook version, build number, and the steps to reproduce the split view error.

Will reinstalling Outlook fix the calendar split view bug?

Reinstalling the application generally will not fix this issue if it is tied to a specific build version (like 2407). You must either wait for a newer update patch from Microsoft or use the temporary view-switching workaround.
