How to stop students from reply all on Office 365

[BronteIT]

I'm looking for a way to stop our students from using the reply all feature on their O365 emails.

 

Does anyone have any suggestions or use anything currently?

 

Thanks in advance!

You can do it via powershell.

 

Get-Mailbox –Resultsize Unlimited | Set-MailboxMessageConfiguration –IsReplyAllTheDefaultResponse $false

Thank you, where do I run this please? and will it only do it for students or all our o365 users?

[Boredguy]

You need to run this from a powershell session that is connected to your Office 365 tenancy (https://www.meetio.com/resources/guides/connecting-exchange-online-powershell has step by step guide on how to connect)

The command I provided will set all users to have the default "reply" set to "Reply to All" disabled, and that is what we have for our staff and students trust wide.

That's run via the O365 Powershell module, you'll need to narrow it down with a subset of users depending on how you group them (do you set the department attribute for instance?)

You can do it via powershell.

 

Get-Mailbox –Resultsize Unlimited | Set-MailboxMessageConfiguration –IsReplyAllTheDefaultResponse $false

 

It's worth noting that this won't prevent students from choosing to Reply All, it just changes the default to Reply instead of Reply All.

What's the actual problem that you're trying to solve? Is it that students are hitting Reply All to messages sent to groups (e.g. All Students)?

 

Applying certain permissions to send to groups is a possibility, you can also teach staff to put group email addresses into the BCC section as a simple thing.

Normally the problem is they hit the reply button thinking it's just going to the original sender, but it defaults to reply all so everyone in the list gets it. It is rare you ever need to reply to all, but MS thought otherwise

Yes i'm trying to block them from sending to groups like all students

Can you not set the restrictions so only X can be a nominated sender. I did this for our O365 groups.

X can be a group, ie All staff and certain students

[BronteIT]

Please could you tell me how to set those restriction on groups? I have a all students group in O365 and on AD

[Boredguy]

It depends if you are using AD synchronised e-mail groups, or if they are cloud based.

 

If they are Active Directory groups, you can edit the dLMemSubmitPerms attribute in AD with the CN valid of a group that can send to it eg CN=Staff,OU=Users,DC=School,DC=Internal would only allow users in the Staff AD group to send.

 

If it's a cloud based group, it should be similar via the GUI
