If you’re hosting your email with Microsoft’s Office 365 service, you may be using shared mailboxes. You should if you aren’t, they’re a great way to create email addresses that don’t consume a license. Shared mailboxes can also be shared. <\/p>\n\n\n\n

The Problem<\/h2>\n\n\n\n

I have a quite a few domains added to my Office 365 account and I wanted to create unique shared mailboxes for a couple of my domains. So I logged into Office365 and go to create the 2 shared mailboxes. <\/p>\n\n\n\n

I wanted the following<\/p>\n\n\n\n

social@domain1.com
social@domain2.com <\/p>\n\n\n\n

I created the first shared mailbox without any issue, then when trying to create the second shared mailbox I came across this error. <\/p>\n\n\n\n

Microsoft 365 Admin Center – Error message <\/figcaption><\/figure>\n\n\n\n

The Solution <\/h2>\n\n\n\n

You can’t do this through the admin center because it tries to enforce uniqueness of the alias but does not take into account the domain name. Which I think is kind of crazy, there has to be literally thousands of users that would need this functionality. <\/p>\n\n\n\n

You have to use PowerShell<\/a> to achieve this. First, you’ll need to connect your local session to your office365 account. You can do this following the steps outlined in the following Microsoft help document.<\/a> I’ll outline the steps below incase the document moves or disappears.<\/p>\n\n\n\n

Step One.<\/p>\n\n\n

\n$UserCredential = Get-Credential\n<\/pre><\/div>\n\n\n
\"\"
You will be prompted to enter your admin console admin credentials<\/figcaption><\/figure>\n\n\n\n
Step Two – Connect to Office365<\/p>\n\n\n
\n$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https:\/\/outlook.office365.com\/powershell-liveid\/ -Credential $UserCredential -Authentication Basic -AllowRedirection\n<\/pre><\/div>\n\n\n
Step Three  – Connect the session <\/p>\n\n\n
\nImport-PSSession $Session -DisableNameChecking\n<\/pre><\/div>\n\n\n
If you don’t see any errors, you can move onto the next step. If you see the following error: <\/p>\n\n\n\n
Import-PSSession :<\/g> Files cannot be loaded because running scripts is disabled on this system.<\/p><\/blockquote>\n\n\n\n
You will need to change your PowerShell Execution Policy<\/a><\/p>\n\n\n\n
Step Four – Create the shared mailboxes <\/p>\n\n\n
\nNew-Mailbox -Name "Social Mailbox" -Shared -PrimarySmtpAddress social@domain2.com\n\n<\/pre><\/div>\n\n\n
Step Five – Remove the session<\/p>\n\n\n
\nRemove-PSSession $Session\n<\/pre><\/div>\n\n\n
PowerShell Execution Policy <\/h2>\n\n\n\n
I found this information over on Tachytelic.net<\/a> thanks Paulie! <\/p>\n\n\n\n
Open PowerShell as the administrator <\/p>\n\n\n
\nSet-ExecutionPolicy RemoteSigned\n<\/pre><\/div>\n\n\n
Select ‘Y’ when prompted and you’ll be able to connect. <\/p>\n","protected":false},"excerpt":{"rendered":"
