Hi gablake

If these contacts were meant to be shared within the organisation, would you not simply import them into Exchange Online as external contacts so they appear in the GAL?

Any reason specifically for the contacts going into a shared mailbox? What would you like to achieve?

Hi Chris.

The Contact Group in the Shared Mailbox was deleted and can not be recovered. Only certain users have been given access to this Shared Mailbox.

So I am wanting to create the orginal mailbox. I have created the Contact Group I just need to populate it with the contacts from the csv file. If it wasn't for so many contacts I would do it manually.

Thanks for reaching out.

Ah, I see, it is restoring what was in place.

In that case you should be able to do it by creating and giving yourself full access to the shared mailbox, opening it in your Outlook so it's alongside your mailbox. Import the contacts into the shared mailbox via Powershell and then create the contact group after the import. If you have an issue doing this I would consider temporarily converting the mailbox to a regular mailbox with credentials and then Powershelling the CSV directly into the mailbox, where again you can then create the contact group in your Outlook.

Others may have some other methods here based on their experience.

Best, Chris
