Office 365 Groups

I just did this:

[PS] C:\> $Users = (Get-Recipient -RecipientPreviewFilter {RecipientTypeDetails -eq "UserMailbox" -and CustomAttribute3 -ne "N"}
[PS] C:\> Add-UnifiedGroupLinks -Identity O365Group -LinkTypeMembers -Links $Users.Name

This creates an array of all user mailboxes in the tenant that are not marked with a value in one of the customized attributes. I then use the array as input to Add-UnifiedGroupLinks, which added all (30) the users to the group.

I forgot that I had this example in Chapter 15 of the Office 365 for IT Pros ebook... PowerShell is great!

I understand that 1000 members are a soft limit as if it extends this number, it can get slower when accessing. But it will be one time actions and I mean that some people will leave this group.

If you are getting throttled when adding 2500 users with Set-UnifiedGroup, I agree that splitting the users to be added into chunks could be a solution...the other way around could be to create a more sofisticad PowerShell script with some Re-Try logic so you can overcome the throttling
