Scenario

You have deployed the Exclaimer Outlook Add-in, and you notice that your signatures are not showing on Outlook desktop, but they are showing on Outlook Web without any issue.

Reason

The Exclaimer Outlook Add-in feature uses a connected service which is only available when the option for Optional connected experiences is enabled in Outlook.

Resolution

To resolve this issue:

Step 1: Check the Exclaimer Outlook Add-in Pre-requisites.

Pre-requisites 

Mailbox type:

  • Microsoft 365 mailboxes only

Windows

  • Outlook on Windows (Microsoft 365 Subscription) [version 2409 (Build 18025.20000)]
  • Outlook on Windows (Retail Perpetual) [version 2501 (Build 18429.20132)]
  • Outlook 2024 on Windows (Volume-licensed perpetual) [version 2408 (Build 17932.20222)]
  • Microsoft Outlook Web Access
  • Microsoft Windows 10, Windows Server 2016 or above

Mac

  • iOS: Outlook version 4.2433.0 or above

Microsoft 365 Plan

  • Your Microsoft 365 plan must allow access to deploy Microsoft 365 Apps through Microsoft AppSource. Certain plans, such as Office 365 E2 do not support this.

Step 2: Make sure the Optional connected experiences option is enabled in Outlook.

To enable the Optional connected experiences option in Outlook:

  1. Log in to the Outlook Desktop App.

  2. Select File from the ribbon bar. 
  3. Select Options from the menu sidebar. 
    The Outlook Options window is displayed.

  4. Select Trust Center then select Trust Center Settings....



  5. Select Privacy Options, then select Privacy Settings...
  6. Check the Turn on optional connected experiences option.



  7. Select OK to save the changes.
