Turn Off Outlook Roaming Signatures for Atlas Ink

Turn off Outlook roaming signatures with Exchange Online PowerShell, so the signatures Atlas Ink pushes show up in Outlook on the web and new Outlook.

Before you begin

  • An Exchange Administrator or Global Administrator account in your Microsoft 365 tenant
  • A Windows, macOS or Linux computer with PowerShell 7 or Windows PowerShell 5.1 (Azure Cloud Shell also works)

When you need this

Atlas Ink checks this setting for you on the Rollout tab once Exchange is connected:

  • "Turn off Outlook roaming signatures in this tenant": roaming signatures are still on. Follow the steps below.
  • "Couldn’t check whether Outlook roaming signatures are turned off": Atlas couldn't read the setting. Step 3 tells you whether it is already in place.
  • "Outlook roaming signatures are turned off" (green): nothing to do.

Step 1: Install the Exchange Online PowerShell module

Skip this step if you have used Connect-ExchangeOnline on this computer before, or if you are in Azure Cloud Shell, where the module is already installed.

Install-Module -Name ExchangeOnlineManagement -Scope CurrentUser

Step 2: Connect to Exchange Online

Sign in with your Exchange Administrator or Global Administrator account when prompted.

Connect-ExchangeOnline

Step 3: Check the current value

  • True: roaming signatures are already off. Skip to step 5.
  • False: continue with step 4.
Get-OrganizationConfig | Select-Object PostponeRoamingSignaturesUntilLater

Step 4: Turn off roaming signatures

Run this once. It applies to the whole tenant and returns no output when it succeeds.

Set-OrganizationConfig -PostponeRoamingSignaturesUntilLater $true

This doesn't change anyone's mail flow. Classic Outlook for Windows and Mac keeps its local signatures either way; Atlas Ink's coverage table on the Rollout tab shows which Outlook apps a pushed signature reaches.

Step 5: Confirm the change

Run the check again. It should now report True. Then disconnect.

Get-OrganizationConfig | Select-Object PostponeRoamingSignaturesUntilLater
Disconnect-ExchangeOnline -Confirm:$false

Step 6: Recheck in Atlas Ink

In Atlas, open Ink, go to the Rollout tab and click Recheck on the roaming-signature card. When the card turns green, push signatures as usual.

If the card still says Atlas couldn’t check the setting after step 5 reported True, the setting is in place: Atlas only lacks permission to read your organization settings. Continue with your rollout, and confirm it by pushing a signature to one test user and composing a new message in Outlook on the web.

Turning roaming signatures back on

If you stop using Atlas Ink and want Outlook to manage roaming signatures again, an Exchange administrator can reverse the setting:

Set-OrganizationConfig -PostponeRoamingSignaturesUntilLater $false
