Powershell to update Office365 user attributes


I have located each mailbox that does not have archiving enabled.   Using the following.
Get-Mailbox |Where {$_.archivedatabase -eq $null}

For each of these mailboxes that do not currently have archiving, I need to:

- set msExchArchiveName to the name of the user
- set msExchRemoteRecipientType to 3

And then perform a directory sync.

Please help with this script.  I am very new to powershell.

Hi, we actually do not have an on premises server.    

I am currently getting this error below when trying to turn on archiving for most of our users.  

I found this article which appeared to address the same issue, and instructed me to set the values for msExchArchiveName to something and then set msExchRemoteRecipientType to 3.  


Here is the error I get in powershell when trying to enable archiving:

The following error occurred during validation in agent 'Windows LiveId Agent': 'Can't enable the archive for
'donotreply' because their primary mailbox is located on an on-premises server. To enable a cloud-based archive
mailbox for this user, you must use your on-premises Exchange admin center or Exchange Management Shell.'

As you don't have on premise exchange then only option is to manually modify the attributes on local active directly for each user.
