I am trying to add new members to our email list and keep getting a message that says the following "Response Content is Null". Why is that happening?

    Hello

    The "Response Content is Null" error usually happens due to a temporary web glitch, or because the specific email list type cannot be modified through the standard Exchange portal.

    Please try these two quick workarounds to add your new members:

    1/ Try Incognito Mode (Fixes web glitches)

    Open a new Private/Incognito browser window, log back into your admin/Exchange portal, and try adding the members again.

    2/ Use the Entra Portal (For Security Groups)

    If your list is a Mail-Enabled Security Group, sign in directly to the Microsoft Entra My Groups Portal. Find your group and add the members there.

    If this issue still persists, please reply with the name of the email list. Your IT Admin may need to check your Owner permissions or update the list directly via PowerShell.

    Looking forward to hearing from you.
