Hi LouisESimobe,

Welcome to post in the community, it's my pleasure to assist you0

For this issue, as an admin in the organization, you can try Increase the maximum mailbox size for the affected user, or let the user to delete email messages from the mailbox of the user to free some space in it to see if it helps. To get more information, please refer to the steps:

a. To increase the maximum mailbox, there is the corresponding article:

Note: After increased, the sync could need some time, please wait 24 hours to check the result.

b. To delete the emails from the mailbox, except for deleting the emails directly, the affected user also can use the function of Outlook desktop, like Mailbox Cleanup tool(File> Mailbox Settings> Tools)

If the issue persists, to provide further assistance, we'd like to know which the organization's environment, like pure on-prem, hybrid or pure cloud.
