 Usually this issue happens if the IE browser is not the default browser in the local machine.

So please check the browser settings like below.

To make IE your default browser, follow the steps:
1. Click the “tools” menu at the top of Internet Explorer.
2. Then click “Internet Options” in the list.
3. Click on the “Programs” tab.
4. Look in the “Default web browser” section of the window.


If this section looks like this, then Internet Explorer is your default browser.
After changing this setting, please try from outlook again.




Even after this, the issue is not resolved and if you have Mozilla Firefox in your system, please uninstall the browser and try.


Hopefully these options may help you!
