Outlook Calendar hours view

Question

When I click on my calendar icon in Outlook, it defaults to view the early morning hours (12 - 7 AM) - which are grayed-out non-working hours - instead of my work hours. This did not happen before today.

Hi @G. Stein, 

Welcome to the Microsoft Q&A forum. 

Thank you very much for reaching out regarding your Outlook Calendar opening at the early morning hours (12–7 AM) instead of your working hours. I appreciate your patience and the details you provided. 

This behavior usually occurs when a calendar view setting has changed, your working hours or time zone has shifted, or Outlook encounters a temporary view cache glitch. 

Here are my recommendations, please follow the steps below: 

1/ Go to File > Options > Calendar 

In the Work hours and location section: 

• Set the correct Start time and End time (e.g., 8:00-17:00). 
• Select your appropriate Work days. 
• Verify that your Time zone is correct. 
• 

2/ In the Calendar view (main Outlook window) 

• Open the View tab. 
• Switch to Work Week (or your preferred view). 
• 
• Click Reset View to restore the default layout. 
• 

3/ Resetting Outlook view with a command  

• Close Outlook. 
• Press Win + R and run: outlook.exe /cleanviews  
• 

(Note: this resets all custom calendar views to default.)

4/ Contact Microsoft Support   

If the issue persists even after these steps, it may stem from a deeper system-level cause. In this case, I recommend contacting your organization's IT administrator, who can submit a support request to Microsoft through the Microsoft 365 Admin Center. They’ll be able to access system-level information to investigate the issue thoroughly and provide assistance. At the very least, they can offer the most effective workaround to ensure your experience remains smooth and secure.

I hope this information is helpful. Should you have any further questions or need additional assistance, feel free to reach out.   

I look forward to hearing your thoughts on this.
