Hi,
Thanks for bringing this up and for sharing the screenshot. I am here to help.
To confirm, is this account a work/school (Exchange/Office 365) mailbox or a personal Outlook.com/Hotmail mailbox? That will decide whether you can fix this yourself or if it’s being blocked by an organization policy.
Looking forward to your reply.
