How to Fix Outlook Calendar Opens and Then Closes
Question details
The user needs to resolve an issue where the Outlook calendar crashes or closes immediately upon opening.
- Product
- Microsoft Outlook
- Device & OS
- not provided
- Scenario
- Accessing the calendar feature within the Microsoft Outlook desktop application.
- Observed behavior
- The Outlook calendar window starts to open but immediately closes without displaying any explicit error messages.
Ensure you have your Outlook account login credentials handy, as creating a new profile or repairing the application may require you to sign in to your email account again.
Launch Outlook in Safe Mode and Disable Add-ins
Running Outlook in Safe Mode bypasses third-party add-ins, which are a common cause of unexpected calendar crashes.
Often, a recently installed or updated third-party add-in conflicts with Outlook's calendar module. Safe Mode allows you to isolate the problem by loading the application without these extensions.
Press the Windows key + R on your keyboard to open the Run dialog box.
Type 'outlook.exe /safe' into the text box and press Enter to launch Outlook in Safe Mode.
Try opening the calendar. If it remains open without crashing, the issue is likely caused by an add-in.
Go to File > Options > Add-ins. Select 'COM Add-ins' from the Manage drop-down at the bottom and click 'Go'. Uncheck all add-ins to disable them, click OK, and restart Outlook normally to see if the issue is resolved.
Repair the Microsoft Office Installation
A damaged or missing Office installation file can cause Outlook components, including the calendar, to fail.
Create a New Outlook Profile
A corrupted Outlook user profile can prevent the calendar from functioning correctly.
Try WPS Office as a Reliable and Free Alternative
If you are experiencing persistent issues with Microsoft Office applications crashing or failing to open, consider switching to WPS Office. It provides a lightweight, highly compatible suite of office tools that makes handling documents, spreadsheets, and presentations seamless without the heavy system load.
- 1. Download the software: Visit the official WPS website and download the free installation package for your operating system.
- 2. Install WPS Office: Run the downloaded setup file and follow the straightforward on-screen instructions to complete the installation in minutes.
- 3. Open your files: Launch WPS Office and directly open your existing Microsoft Office documents to continue working without interruption.
Frequently Asked Questions
Why does Outlook close by itself when I click the calendar?
This typically happens due to conflicting third-party COM add-ins, a corrupted Outlook user profile, or damaged Microsoft Office installation files that fail to load the calendar module.
Does starting Outlook in Safe Mode delete my emails or calendar events?
No, Safe Mode simply launches the application with basic settings and disables all add-ins for troubleshooting purposes. Your emails, calendar events, and account data remain completely intact.
What is the Microsoft Support and Recovery Assistant?
It is a free diagnostic tool provided by Microsoft that helps identify and automatically fix various complex issues with Microsoft Office applications, including Outlook startup errors and sudden crashes.
How do I access my calendar if the Outlook desktop app keeps crashing?
You can temporarily access your calendar by logging into Outlook on the web (via Outlook.com or your Microsoft 365 web portal) using your internet browser while you troubleshoot the desktop application.
