Hi all,
Is there away to disable reactions for outlook emails for all the org as an admin?

This is business messaging not a social media platform.

@VNJoe Hi, I don’t understand what you mean by this?

This is an entirely unwelcome and unprofessional update.

@wcsand , I don't know if this is new since December, but per MS's own documentation at
Reactions in Microsoft Outlook - Microsoft Support, in the Information for Administrator section, you SHOULD be able to open a support ticket for your tenant to be placed on a block list for this feature:

SolutionIt's on the roadmap, supposedly starting next month:
@VNJoe, Absolutely agree, but I was offering a solution in the meantime: make them abide by their documentation. Hopefully the roadmap feature is still on track for release in June, but I'd personally consider opening a ticket anyway, in case the rollout gets delayed.

Insert your admin UPN below and run
# Connect to Exchange Online
Connect-ExchangeOnline -UserPrincipalName <email address removed for privacy reasons> -ShowProgress $true
# Define the custom header and its value
$CustomHeaderName = "x-ms-reactions"
$CustomHeaderValue = "disallow"
$RulePriority = 1
# Create the mail flow rule
New-TransportRule -Name "Drop Reactions" -SetHeaderName $CustomHeaderName -SetHeaderValue $CustomHeaderValue -Priority $RulePriority
# Disconnect from Exchange Online
Disconnect-ExchangeOnline -Confirm:$false

Careful with this.
It disables the notification side but not the sending side.
Sending user still sees that they sent the Reaction, but recipient never receives it.
