When to use this: Apply these steps when the symptoms match and you can access the relevant Microsoft account or administrator.

1. Navigate to the Number tab, select Time from the category list, and choose a format such as hh:mm:ss to ensure Excel recognizes the entries as temporal data rather than plain numbers.

2. Once formatted correctly, apply the standard SUM formula, such as =SUM(A1:A14), to calculate the total duration.

2. Test the same action in a private browser session or a new blank file to isolate account vs file issues.

3. Capture exact error text and screenshots before contacting Microsoft Support or your administrator.
