Users are receiving messages that their mailbox is at or close to the mailbox quote. They are currently using Office 365 which has a quota of 50GB per mailbox. When they originally signed up, it was 25GB and Microsoft increased it, but some accounts did not automatically get updated to the 50GB. We need to go in and increase it manually. Here are the steps to do it.


1. Open Windows Powershell (This can be downloaded from logging into the Office Portal and going to Office 365 settings, software and download from there)

2. Copy and paste the following command into the powershell -

$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell/ -Credential $LiveCred -Authentication Basic -AllowRedirection

3. Enter your admin login and password.

4. Copy and paste the following command into the powershell -

Import-PSSession $Session

5. Copy and paste the following command into the powershell -

Set-Mailbox <UserID> -ProhibitSendQuota <Value> -ProhibitSendReceiveQuota <Value> -IssueWarningQuota <Value> (Change Userid to the users e-mail and change the <value> to 45GB. (It won't take 50GB, but you should be able to put 49GB)


That should be it. Once that is done you can go back in and look at their quota and should see that it has increased to whatever size you give it.
