Microsoft 365 sign-in screen appears blank when configuring a connection to Exchange Online

This problem is not caused by CodeTwo products but is related to Internet Explorer settings on your machine. You can resolve this issue by restoring the default settings.

To do so, follow the steps below:

  1. Open Internet Explorer, click the Tools button in the top right corner and select Internet options from the menu (Fig. 2.).
