Sending, receiving, and organizing email in Outlook on the web for business
Dear Christian2218
Good day! Thank you for posting to Microsoft Community. We are happy to help you!
Based on your description, I have a general understanding of your problem, given that your problem is happening on Outlook on the web, because our forum lacks relevant knowledge and permissions, so to better help you and not waste more time, 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 using admin account, please kindly ask admin within your organization for help.
Thanks in advance for your understanding! Your patience and cooperation will be highly appreciated. Hope you all the best!
Sincerely,
Kerry Chen | Microsoft Community Moderator
