Open Exchange Management Shell and execute the New-Mailbox cmdlet using the following example as a template:
1 | New-Mailbox -Alias MySharedMailbox -Name 'My Shared Mailbox' -Database 'MAIL1\First Storage Group\Mailbox Database' -OrganizationalUnit 'mikefrobbins.demo/My OU/Users/Mailbox' -Shared -UserPrincipalName mysharedmailbox@mikefrobbins.demo |
The following cmdlet assigns full access for the mailbox to a group in Active Directory named “My Shared Mailbox Admins” which needs to exist in AD prior to executing this command:
1 2 | Get-Mailbox -Identity 'My Shared Mailbox' | Add-MailboxPermission -User 'My Shared Mailbox Admins' -AccessRights FullAccess |
This cmdlet allows members of the “My Shared Mailbox Admins” group in Active Directory to be able to send email from the “mysharedmailbox@mikefrobbins.demo” email account:
1 2 | Get-Mailbox -Identity 'My Shared Mailbox' | Add-ADPermission -User 'My Shared Mailbox Admins' -AccessRights: ReadProperty, WriteProperty -Properties 'Personal Information' -ExtendedRights Send-As |
Once these steps are completed, any AD user who is added to the “My Shared Mailbox Admins” group in AD will be able to open the “mysharedmailbox” and send email from this account.

Thank you Mike!
Awesome! Excellent write up! Thanks.
I followed your steps and I was able to create the shared mailbox and permissions. Now it will not give me permission to access the account. When I look at the “Send As” and “Full Access” permissions, it shows the security group that is suppose to manage the account. Where else should I investigate?
Add your user account to the “My Shared Mailbox Admins” group in Active Directory. Log completely off the network and back on for the security changes to take effect.

Thanks Mike! 🙂
Have a similar walk through for Exchange 2010?
