A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
You probably just need to add the webmail server site as a “Trusted Site” in the Internet Explorer security options.
With Windows 7, do the following steps in Internet Explorer 8:
- From “Tools” menu, select “Internet Options”.
- On the “Security” tab, click “Trusted site” in the “Select a zone to view or change security settings.” panel.
- Click the “Sites” button.
- Under the “Add this website to the zone:”, enter the URL for the web mail site and click the “Add” button.
- If the URL starts with HTTP instead of HTTPS, make sure that the “Require server verification (https:) for all sites in this zone.” check box is cleared.
- Press the “Close” button.
- Press the “OK” button.
