If you get further dialogs such as First things First, click Accept: Now hold down Ctrl and click the Outlook shortcut on the taskbar, presuming it is pinned.

If that doesn’t work, you can use Task Manager to end the Outlook process. Close Outlook by clicking the X at top right. Will it complete in its own good time? Not sure, but for sure it takes longer than you want to wait in order to get your email. You start Outlook, it loads plug-ins, then presents a dialog that says “Processing”. I have seen this a couple of times recently, both cases where Outlook 2016 is installed.
