When setting up your Liscio email integration using an Outlook email address, you may be blocked by a Microsoft approval screen that states "Need admin approval" like this:
If you run into an approval screen while setting up the Outlook integration in Liscio, it may be that a more secure configuration was selected in your firm’s Active Directory / O365.
Your O365 admin will need to grant tenant-wide admin consent to the Liscio app.
Granting tenant-wide admin consent requires you to sign in as a user that is authorized to consent on behalf of the organization.
You must be a global administrator to turn on the admin consent workflow.
After consent/approval, users can return to Liscio and connect to Outlook again.
