Posted on by ttusin

As part of our onboarding process, we are using power automate to add users to relevant, groups, security groups and shared mailboxes.

However, I cannot find the appropriate operation to add a user to an existing shared mailbox. Help!

Thanks

If add the member to the group with the shared mailbox dosen't work, I'm afraid there isn't functionality to do this in PowerAutomate today.
So you have to
1. Look into calling a desktop PowerAutomate flow from the cloud flow to do this or
2. Send an email to a person who can do it manually.

The following steps to add users in a shared mailbox copied from https://www.nucleustechnologies.com.

Sign in to Exchange Admin Center and go to Groups and select Shared Mailboxes.
The shared mailboxes will appear on the screen, select the mailbox to which you want to add members to.
From the Details Pane menu, select Edit.
Now, click the ‘Add members‘ button on the top.
The list of users in your organization will display in the pane. You can select multiple users by selecting the checkbox next to their names, or you can also search for the users if you have a long list.
After selecting the users, click Save.
It will take at least 60 minutes to show up the added users to the shared mailbox.

it's crazy that there isnt an easier way, but you can call an azure runbook from power automate. and the runbook can contain the powershell.

over in azure, create a runbook with the powershell calls
Add-MailboxPermission -Identity $MGREmail -user $User -AccessRights FullAccess
Add-RecipientPermission -Identity $MGREmail -Trustee $User -AccessRights SendAs -Confirm:$false

the runbook needs an automation acccount. and you have to auth using it
Get-AutomationConnection -Name 'AzureRunAsConnection'
$UserCredential = Get-AutomationPSCredential -Name "Ex_Auto"
Connect-ExchangeOnline -Credential $UserCredential

i spent "some" time figuring out how to auth from a runbook. it was definitely the hardest part as runbooks were very new to me.

i am not sure why the exchange folks can't/won't expose some stuff in Graph or make some native Flow options.
