Mapping an Exchange Mailbox in Outlook via Powershell

Markus Danner 26

Hello,

is it possible to map a Shared Mailbox in Outlook (2016) via Powershell-Script wihtout the AutoMappping Feature?

For example with the ComObject?
Add-Type -assembly "Microsoft.Office.Interop.Outlook"
$Outlook = New-Object -comobject Outlook.Application
$namespace = $Outlook.GetNameSpace("MAPI")

Best regeards

With Powershell? Why not just use:

Add-MailboxPermission -Identity <Mailbox ID1> -User <Mailbox ID2> -AccessRights FullAccess -AutoMapping:$false

I need a Script for Adding the Shared Mailbox into outlook which can called by the user in his Userprofile.
We've got users, who switch their workplace and they always hav to ad the shared mailboyes manually into Outlook.
The Permission of the Mailbox are correct.

Ok, well automapping will take care of that :)

Any reason not to set that if the need full access?

@Markus Danner

After enable AutoMapping, shared mailbox will show in Outlook client automatically without any other action. When login mailbox in new client, the shared mailbox will also show automatically.

So, I am confused, you don’t want the mailbox to appear automatically, but you also want to use a script to add it automatically. Why do you want to do this?

If you really want to do it, you can try to post this question in Outlook for Developers forum. It may be help to you.

Thnaks for ur answer.
We can't or want use automapping, because there are some reasons, some users don't need all the mailboxes, they have acceess to.

So is it possible to activate automapping only for several users via Policy oder Option?

You ca have a look about this article: Add-MailboxPermission

AutoMapping is enabled by default, if you don't want to enabled it for some mailboxes, you need to use command to add permission and set the value of "-AutoMapping" as "false"

Not possible to use a GPO or anything like that. You would have to create your own scripting or logic to determine which ones you want to automap and which ones you do not
