Solution 1Recommended

Clear Browser Cache and Test in Private Mode

Use this solution to eliminate corrupted temporary files or incompatible browser extensions that may be causing the web application to malfunction.

Often, display glitches like disappearing calendars or continuous loading screens are caused by outdated cache files or conflicting browser extensions. Clearing your browsing data forces the web app to load fresh resources.

Open Browser Settings

Click the menu icon (usually three dots) in the top-right corner of your browser and navigate to 'Settings' or 'History'.

Clear Browsing Data

Locate the option to clear browsing data. Ensure that 'Cookies and other site data' and 'Cached images and files' are selected, then clear the data.

Test in Incognito Mode

Open a new Incognito or InPrivate window. Log into your Outlook on the web account to verify if the calendars and profile settings are displaying correctly without loading errors.

Clear Browser Cache and Test in Private Mode

Quick Check: If the issue is resolved in private mode but returns in a normal window, try disabling your browser extensions one by one to find the culprit.

Solution 2

Request Administrator Backend Support

If browser troubleshooting fails or the problem affects multiple users, your Microsoft 365 administrator must escalate the issue.

Frequently Asked Questions

Why does my Outlook web calendar keep disappearing after it loads?

This is typically caused by a corrupted browser cache or a conflicting browser extension interrupting the script execution. Clearing your cache and testing in an Incognito window usually resolves the display glitch.

How can I restore missing profile options in Outlook on the web?

If options like Language and Time or Mobile devices are missing, it may be a temporary interface bug or an account permission issue. First, try clearing your browser cookies. If the options remain hidden, your Microsoft 365 admin will need to submit a service ticket to reset your backend configurations.

Why is there a continuous loading indicator on my Outlook web page?

An infinite loading loop happens when your browser fails to retrieve updated assets from the Microsoft servers. A quick refresh using Ctrl+F5 or logging in via a private browsing session can bypass the outdated cached files causing the loop.
