    Hi,

    Thank you for reaching out to the Microsoft Community. I am happy to assist you.

    Regarding your issue, to increase your mailbox storage in Microsoft 365 Business Standard, here are a few options you can try: 

    1. Enable Archive Mailbox:
    • You can enable an archive mailbox for your account which provides additional storage space for older emails, with auto-expanding archiving.

    For more details, please refer to: Enable archive mailboxes for Microsoft 365 | Microsoft Learn  

    1. Upgrade to a Higher Plan:
    • Consider upgrading to Microsoft 365 Business Premium or Exchange Online Plan 2. These plans offer larger mailbox capacities. For example, Exchange Online Plan 2 provides a 100GB mailbox and 1.5TB of archive storage.

    For more details, please refer to: Compare Microsoft Exchange Online Plans Microsoft 365

    1. Shared Mailbox:
    • You can create a shared mailbox, which doesn't require a separate license and can be used to offload some of your email storage.

    To upgrade your plan please ask your IT Admin to help with the process via Microsoft 365 admin center.
