Solution 1Recommended

Troubleshoot Outlook on the Web

Use this solution if you access your Outlook emails via a web browser, as browser cache or extensions often cause input field issues.

When using the web version of Outlook, temporary site data or browser incompatibilities can sometimes block user interface elements like text fields.

1
Use a different browser

Open a different supported web browser (such as Safari, Chrome, or Edge) and log into Outlook to see if the recipient fields work.

2
Clear browser cache

Navigate to your browser's settings or privacy menu, locate the clear browsing data option, and clear your cached images and files.

3
Try private browsing

Open a new Private or Incognito window in your browser, log into Outlook, and attempt to compose an email.

Tip: Using a Private or Incognito window temporarily disables most browser extensions, which helps identify if an ad-blocker or privacy extension is causing the conflict.
