Hello,

I have a problem with the limit of my inbox.

Indeed, it is blocked at 50 GB where it should be at 100 GB.

I don't know how to explain it on two people created at the same period with the same rights and same license.

Account with problem:

50go

Normal account:

100go

Would you know if it is possible to do something, knowing that the test of diagnose microsoft tells me that my limit of box is 100GB.

Thank you for your help,

Sincerely.

    Hi @Romain ,

    Is the diagnosis in the Microsoft 365 admin center showing that the current mailbox quota is below the maximum allowed for the assigned license?

    If so, you can refer to the following command to increase the size of the specified mailbox:

    Set-Mailbox userfour@aholiclh.onmicrosoft.com -ProhibitSendQuota 99GB -ProhibitSendReceiveQuota 100GB -IssueWarningQuota 98GB

    To check whether the mailbox has the current quota list attached, run the following PowerShell cmdlets:

    Get-Mailbox <User ID> | Select *quota*

    For more information, please refer to this link: Increase or customize Exchange Online mailbox size - Exchange | Microsoft Learn
