Some users on macOS 10.14 have experienced issues logging back into Mac Mail after Modern Auth is applied to their accounts. Specifically, after successfully responding to the Duo prompt, the pop-up window will remain blank except for a spinning icon and never finish adding the account to the application. This issue has been resolved by having users connect to the UO VPN when initially setting up their account with Mac Mail. After logging in successfully once while connected to the VPN, any removing or re-adding of the account again to Mac Mail should not need the VPN.
