How it works

Exclaimer Cloud is extremely flexible, providing multiple setup options depending on your particular needs.

  • Server-Side Configuration
    Allows signatures to be applied to emails sent from all devices and email clients by integrating within your mail route the Exclaimer Azure hosted service located within the closest availability zone. Emails are imprinted with a signature within the smarthost and then returned to Exchange Online for delivery to the recipient.
  • Client-Side Configuration
    Allows signatures to be applied to emails during composition within Outlook, OWA or Apple Mail. A delivery mechanism ensures the email signature is established in the supported email client and thus this configuration requires no mail flow to occur through the Exclaimer service.
  • Server-Side & Client-Side Configuration
    Marries the best features of both of these configurations; emails signatures are both deployed to compatible email clients but also passed through to the Exclaimer smarthost too, so that all emails undergo the imprinting process. Deduplication occurs so that the email only receives a single version of the correct signature.

Email signatures are designed and managed in the Signatures for Office 365 portal

Design email signatures with the Exclaimer Cloud drag-and-drop signature editor. Create multiple signatures and assign them to individual users, groups/departments or even assign a signature based on contact details such as a job title.

An email is sent from any Internet-enabled device

The email signatures will then be automatically downloaded to networked users’ Outlook client via an agent (no add-in required).

Emails pass from Microsoft 365 (formerly Office 365) to Azure

Each email sent from your organization passes from Microsoft 365 (formerly Office 365) and is routed to one of Exclaimer’s regional Azure servers where Signatures for Office 365 is hosted. This means that the service stays within Microsoft data centers around the world, so no email ever leaves the Microsoft Cloud infrastructure. In essence, it is a load-balanced, high-availability Azure service.

Our cloud environment

  • The Exclaimer Azure setup uses load balancing to provide a single network service from our regional Azure servers. If one of these regional Azure servers were to cease operating, traffic is instantly redirected to a backup datacenter to ensure continuity of service.
  • Measures are in place to ensure that the service scales with increased number of tenants, maintaining reliability and uptime. All inbound connections are secured through SSL Certificates and TLS, which are constantly checked to meet current cloud standards.
  • Our 24/7/365 monitoring services automatically detect any service alerts, which are configured with escalation chains. The Exclaimer Cloud Service Health page provides key details on the service and we provide real-time alerts for all subscribers. You can even sign up to receive notifications via email and SMS should you wish.
  • Exclaimer Cloud - Signatures for Office 365 uses state-of-the-art tools and technologies to ensure all aspects of the service are readily available. The service is situated in load balanced environments for reliability and scalability purposes. Network and application traffic is therefore distributed across a number of different servers.

Exclaimer Cloud & the ISO/IEC 27001:2013 Certification

Exclaimer Cloud was awarded the ISO/IEC 27001:2013 Certification for Information Security Management in 2016. The ISO/IEC 27001 Certification is specifically focused on the development and supply of our cloud-hosted signature management service. It measures how our internal processes follow the ISO standard. Certification means a third party accredited independent auditor has performed a thorough assessment of Exclaimer Cloud and has confirmed it is operating in alignment with the ISO/IEC 27001:2013 Certification standard. This makes it one of the most secure Microsoft 365 (formerly Office 365) signature solutions available.

Step 1

Design email signatures using an intuitive Microsoft 365 (formerly Office 365) signature editor tool or choose from a library of professional signature templates, giving them to individuals and groups/department. All of the data is taken from your Microsoft 365 (formerly Office 365) Directory, so it will be 100% accurate, and you can easily manage additional email signature elements such as social media icons, promotional banners and legal disclaimers. You are also able to update any signature element and apply the changes in real time.

Step 2

The email signatures will then be automatically deployed to the supported email clients used by users via a deployment mechanism (see below.)

Step 3

When a user composes an email in a supported email client, the email signature will appear with pre-populated contact details taken from your organization’s Azure Active Directory.

Step 4

Exclaimer Cloud sees the incoming messages, imprints the appropriate signature on every email and passes them back to Microsoft 365 (formerly Office 365) for sending. It does not send emails out on your behalf as this is still done by Microsoft 365 (formerly Office 365). All data is securely managed according to the standards of the ISO/IEC 27001:2013 Certification.

Step 5

With the signature/s added, the emails are passed back to Microsoft 365 (formerly Office 365) via an end point connector that has been set up in Microsoft 365 (formerly Office 365). Signatures will only be added to an email once due to a secured closed loop process between Microsoft 365 (formerly Office 365) and the Microsoft Azure infrastructure.

Step 6

The emails go out as normal, but now have a high-quality signature appended to them. A signature has essentially been ‘stamped’ onto each email. Users will also be able to see Microsoft 365 (formerly Office 365) signatures in their Sent Items folder thanks to the most scalable and secure signature technology available.

High quality signatures added to all emails

Step 1

Design email signatures with the Exclaimer Cloud drag-and-drop signature editor. Create multiple signatures and assign them to individual users, groups/departments or even assign a signature based on contact details such as a job title.

Step 2

The email signatures will then be automatically downloaded to networked users’ Outlook client via an agent (no add-in required).

Microsoft Outlook

Step 3

When a user begins composing an email in Outlook, the email signature will appear in the email with pre-populated contact details taken from your organization’s Microsoft 365 (formerly Office 365) Directory. If more than one email signature applies to a user, they’ll be able to choose one from the drop-down menu in Outlook.
