Hi @James James,

Thank you for posting your question in the Microsoft Q&A forum.

Based on your description, you want to expand your Exchange Online mailbox to 100GB while archiving online.

1. As a tenant administrator, if one of your users has insufficient storage in their Exchange Online mailbox and they want to increase its size, they must be assigned a different subscription license. This is because the size of an Exchange Online mailbox is determined by the subscription license associated with it. To increase the size of a specific user's mailbox, select the button in the following article to launch a diagnostic in the Microsoft 365 Admin Center. The diagnostic will guide you through the process of assigning a different subscription license to a user. Increase or customize Exchange Online mailbox size - Exchange | Microsoft Learn

2.Exchange Online Archiving is available through the following programs. For more information, refer to the documentation: Exchange Online Archiving service description - Service Descriptions | Microsoft Learn
