Greetings, Ella! My name is Arif, I'd be pleased to help you as a Microsoft adviser.
Please take the following actions:
Dear Ella, This is a license issue, according to the error notice "UserHasNoMailboxAndNoLicenseAssignedError." Your admin may not have yet assigned an Exchange online license to your account, or in rare situations, it may be that they have changed the license settings. Unfortunately, the only way to resolve this issue is by contacting your admin because it is a license-related issue.
For more information kindly refer to the below thread link which is related to your issue:

If the steps outlined above work for you, kindly let me know. If not, please feel free to respond to my chat.
Warm Regards,
Arif
