Hi,
Strictly speaking, this is not an "Outlook issue". This issue is usually related to the web browser you are using.
Which web browser are you using? If you are using Internet Explorer as the default, you can refer to the following Microsoft KB article and try to resolve your issue:

If you are using other browser, such as Chrome or Firefox, you can also refer to this article for solutions:
