Discussion

Define a list of sites, based on URL patterns that can open pop-up windows.

Check Content

This requirement for "Allow pop-up windows on specific sites" is not required; this is optional.

The policy value for "Computer Configuration/Administrative Templates/Microsoft Edge/Content settings/Allow pop-up windows on specific sites" must be set to "Enabled".

Use the Windows Registry Editor to navigate to the following key:
HKLM\SOFTWARE\Policies\Microsoft\Edge

"PopupsAllowedForUrls" must be set as follows:
HKLM\SOFTWARE\Policies\Microsoft\Edge\PopupsAllowedForUrls\1 = mydomain.com
HKLM\SOFTWARE\Policies\Microsoft\Edge\PopupsAllowedForUrls\2 = myagency.mil

If configured, the list of domains for which Microsoft Edge allows pop-ups may be allowlisted.

Fix Text

Set the policy value for "Computer Configuration/Administrative Templates/Microsoft Edge/Content settings/Allow pop-up windows on specific sites" to "Enabled". A list of allowlisted URLs may be specified here.
