Using New Outlook on Windows for personal email, calendar, and contact management
Dear Ini Nkanga
Thanks for choosing Microsoft Community.
Based on your description, I know the scenario you met. For this situation, since you also meet this on the web, for this, I think the cause of the problem is most likely due to an error on the server backend, because our forum lacks relevant knowledge and permissions, so to better help you, please kindly try to create a service ticket in the Microsoft 365 admin center to support > service requests through navigation, as they have more access permissions than on this forum, and professional engineers will further help you. Note: If you are not admin, please be kindly to contact your admin for help.Thanks in advance for your understanding! Your patience and cooperation will be highly appreciated. Hope you all the best!
Sincerely,
Katherine
