How to assign a password to an Office 365 resource mailbox
This document will walk you through the steps of assigning a password to a new or existing Office 365 resource mailbox. Often times you will have a Skype for Business user account for a conference room (i.e. firstname.lastname@example.org) and you want to have the meeting information automatically appear on your conference room phone. To accomplish this, your resource or room mailbox will need to have the same password as the Skype for Business user account.
To perform these steps, you will need to be an Exchange administrator within your Office 365 tenant.
- To assign a password to a resource mailbox, launch Powershell locally and then use the following cmdlets to get connected to Exchange Online:
$UserCredential = Get-Credential
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection
- To create a new resource mailbox to match your Skype for Business user please enter the cmdlets below. Please note that items highlighted in Red need to be changed to match the account you're configuring.
New-Mailbox -MicrosoftOnlineServicesID $rm -room -Name "Large Conference Room" -RoomMailboxPassword (ConvertTo-SecureString $newpass -AsPlainText -Force) -EnableRoomMailboxAccount $true
- For existing resource mailbox you'll use the cmdlets below. Please note that items highlighted in Red need to be changed to match the account you're configuring.
$newpass="Password1" (Choose a password that matches the password of the Skype for Business user account)
Set-Mailbox -MicrosoftOnlineServicesID email@example.com -RoomMailboxPassword (ConvertTo-SecureString $newpass -AsPlainText -Force) -EnableRoomMailboxAccount $true
At this point you've configured the resource mailbox with a password that matches your Skype for Business user account. You should now be able to sign into Skype for Business on a PC or phone and view scheduled meetings for that account.
