Raise user awareness with a MailTip for external recipients in Exchange Online

Policy tips in Exchange Online can be used for a lot of things: warnings if a user sends confidential information to someone outside the organization if a proper DLP policy is in place or other useful things. One simple and effective MailTip is available for a while now and helps to raise user awareness in writing e-mails.

Nothing special happens, only due to the fact that the MailTip is here the sender probably thinks twice: are all my recipients correct?


So, how to get that MailTips? Through Windows PowerShell of course!

First, connect to your Office 365 tenant with Exchange Online Remote PowerShell:

$cred = Get-Credential

Connect-MsolService -Credential $cred

 $session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri -Credential $cred -Authentication Basic -AllowRedirection
Import-PSSession $Session -AllowClobber

Afterwards set the Mailtip at the Organization Level:

Set-OrganizationConfig -MailTipsExternalRecipientsTipsEnabled $true

That's it!
