Enable pop-ups in Google Chrome
Turn on pop-ups for webmail in Google Chrome, for one site or for all sites.
For our webmail to work properly in Chrome, you must allow pop-ups.
This example uses Google Chrome on a Mac. Your screen may not match exactly, but the steps are about the same.
If your browser lets you add exceptions to its pop-up blocker, that is better than turning on all pop-ups. In Chrome, you can allow pop-ups from specific sites only, or from all websites.
