Original KB number: 2935743
When you compose or reply to email messages in Outlook on the web (formerly known as Outlook Web App (OWA)) in Internet Explorer, you discover that you can't enter text in the body of the email messages.
This issue may be caused by a third-party antivirus add-on to your web browser.
Disable the third-party antivirus add-on to your web browser. To do this in Internet Explorer, follow these steps:
- Start Internet Explorer.
- On the Tools menu, select Manage add-ons.
- In the list of add-ons, select the add-on that you want to disable, select Disable, and then select Close.
You may have to restart Internet Explorer for the changes to take effect.
