Get-Mailbox | Set-Mailbox -identity -IssueWarningQuota 95GB -ProhibitSendQuota 98GB -ProhibitSendReceiveQuota 99GB If all your users have the same licenses then you can simply run the following PowerShell command to increase mailbox size to 100Gb in Office 365. You can also increase all the mailboxes in one command. Set-Mailbox -identity -IssueWarningQuota 95GB -ProhibitSendQuota 98GB -ProhibitSendReceiveQuota 99GB # Connect to Exchange OnlineĬonnect-exchangeonline -userprincipalname Then prohibit the sending of new mail at 98Gb, so we still have a little room to receive mail until we reach the limit of 100Gb. You want to give the user a warning on time, not when the mailbox limit is reached.

Microsoft has increased in the mailbox limitation in the past, in 2013 and later again for the E3 and E5 plans.
