Exclaimer is proud to announce the launch of a new product feature: Exclaimer Cloud Outlook Add-In

New web add-in simplifies deployment and enhances useability of client-side signatures by utilizing Microsoft’s latest API

25 May 2021, Farnborough

Exclaimer Group is excited to announce a new addition to its popular and powerful client-side capability. The Exclaimer Cloud Outlook Add-In is a new feature based on Web Add-in technology that delivers email signatures to Outlook on the web (OWA). It will also be available for Outlook desktop soon.

Developed and tested in conjunction with Microsoft’s product teams, Exclaimer is the first email signature management solution provider to offer such an extensive and secure range of functionality.

The Add-in joins an already extensive client-side capability allowing users to easily choose their email signature as they compose a message. Users can now enjoy this functionality on Outlook on the web with the full functionality for Outlook Desktop for Windows coming in the next few weeks. Mac users can continue to access Exclaimer’s full array of functionality using the existing desktop agent.

There are multiple advantages to Exclaimer’s new feature for both IT teams and end users. From just a few clicks within the Microsoft 365 Admin Center, an IT team can deploy signatures to every user within the company, wherever an employee is based.

Other benefits for IT teams include:

  • Quick to deploy - only needs to be added to an IT admin center once and can be pushed automatically to all users across all platforms that are currently supported by Microsoft
  • No need to install signatures on each machine
  • Less IT overhead with no separate application to manage
  • Users don’t have to be connected to the network, so there’s no need to deploy a GPO
  • Instant update of signature changes to the entire user base

The advantages for end users include:

  • The option to choose from multiple signatures in Outlook on the web, and with the same functionality for Outlook desktop available soon
  • It’s an easy-to-use Add-In, which provides a visual preview of signature templates
  • Signature templates can be used for different messages (for example representing different brands)

The feature is built using the highest security standards. Exclaimer Cloud is the most powerful and secure email signature management solution on the market. This is backed up with resilient security as evidenced by outstanding scores on SecurityScorecard, robust infrastructure powered by 12 Microsoft Azure datacenters, and our ISO/IEC 27001 Certification.

Daniel Richardson, CTO, Exclaimer comments on the latest product launch: “We are pleased to announce the launch of our distinctive, new email signature Add-In feature. Having worked directly with Microsoft’s product team, we have created the first fully secure, feature rich solution in this space. The feature joins an already extensive client-side capability, giving admins even more power to deliver functionality to their end-users.”

Hitesh Manwar, Senior PM, Office Platform at Microsoft says: “It’s exciting to see Exclaimer use the latest Signature APIs and event-based Outlook Add-ins to deliver their latest signature management solution. The high-quality engagement and feedback from the Exclaimer crew were valuable in bringing out these capabilities. I am sure the new Exclaimer add-in will provide immense value to our M365 customers.”
