Unable to install Outlook Add-in

Hi all, 

I am trying to install the new Outlook add-in but encounter an error when trying to signing in within the add-in in Outlook. Every time I click "Sign in now", a window temporarily pops up but then closes itself.

I then see this message and the same thing happens after pressing "Try again". I have checked to ensure I don't have any pop-up blockers and have tried staying logged in in a separate Chrome/Edge window but haven't had much success.

I have also uninstalled/reinstalled, rebooted my machine but nothing is working. 

Any help would be much appreciated!

    Enable Disabled Add-in

    Select Disabled Items in the drop-down at the bottom of this window, next to the Go button.

    Click Go.

    Select the Add-in that you would like to re-enable.

    Click Enable in the lower-left corner of this window.

    Restart Outlook. Close Outlook, wait for 5 seconds, then start it again.

    Regards,

    Peter
