Disable Outlook "Metered Connection" warning

Question

I connect to the internet using 4G. I have set the connection to "metered" in Windows 10.

Unfortunately this means Outlook displays a "metered network" warning and will not download mail until I click "Connect anyway".

This setting appears to be per account so I have to click this for each account before Outlook can download mail. Outlook also appears to silently forget the setting periodically.

I can't find any way to turn this off in Outlook.

I have found two other superuser questions Settings that reduce Outlook 2016 data usage on a metered connection, while allowing mail and Outlook 2013 shows a metered connection warning on Windows 7; causes Office updates to fail but these relate to Windows 7 and 8 and don't appear to have been resolved.

To be clear, I would like Windows to consider my connection as "metered" but I would like Outlook to treat it as "unmetered". I do not want to stop using Windows 10 or Outlook.

Appreciate any and all ideas, even if it means writing VBA! Thanks

Answer 1

The metered network is a Windows network setting, not Outlook. Unfortunately, you can’t somehow whitelist Outlook for any or all of your connections or prevent Outlook from requesting the network costs before connecting. To bypass this warning, you have to change the “costs” setting for your network connection so it will no longer be a metered network.

See Metered network warning and Outlook not connecting automatically for more details.

Answer 2

That is kind of auto sense feature by Windows 10. When you are connecting to the Internet via 4G, it detects and makes your connection as the metered network. Your Outlook and OneDrive will go offline mode. You can adjust the 'costs' or disable the Metered connection feature completely as shown in below guide for mobile data (3G/4G) connections. https://www.sysprobs.com/how-to-fix-metered-network-warning-in-outlook-onedrive-in-windows
