Update mailbox quota
Hi,
We have Office 365 E3 subscriptions. I noticed that one of our user has 49.5GB of mailbox quota instead of 99GB... I can see that with the Get-Mailbox PowerShell cmdlet and also in the Exch...
Here are the instructions - https://support.microsoft.com/en-us/help/2490230/how-to-set-exchange-online-mailbox-sizes-and-limits-in-the-office-365.
This is the command I tested and worked ok -
Set-Mailbox <account> - ProhibitSendQuota 99GB -ProhibitSendReceiveQuota 100GB -IssueWarningQuota 98GB
After running this command on test mailbox with a smaller quota, it was shown as having a 99GB mailbox available.
Slightly better code because it focuses only on user mailboxes and only processes mailboxes that need to be:
Get-Mailbox -RecipientTypeDetails UserMailbox | ? {$_.ProhibitSendQuota -lt 90GB } | Set-Mailbox -ProhibitSendQuota 99GB -ProhibitSendReceiveQuota 100GB -IssueWarningQuota 98GB
Nice !
