Compare Outlook Roaming Signatures and Exclaimer

Brought to you by Exclaimer

Exclaimer vs Outlook roaming signatures

Microsoft's Outlook for Windows: Signature cloud settings, known as Outlook roaming signatures, allows email signatures to be stored within a user's mailbox rather than on a local device. This means a user's personal signature will be available when accessing Outlook for Windows from a different desktop device.

However, Outlook roaming signatures does not provide the same level of design and control as third-party email signature management solutions as Exclaimer provides. It is also worth noting that Outlook roaming signatures will not synchronize signatures outside of Outlook for Windows, e.g., non-Windows mobiles and tablets, CRMs like Salesforce, etc.

Choosing Exclaimer over Outlook roaming signatures

If you're looking for an easier way to manage email signatures over using the Outlook roaming signatures feature, Exclaimer is the perfect choice for you.

Exclaimer worked with the Microsoft product team, releasing an update to our client-side agent that automatically sets the registry key to prevent Microsoft from updating the mailbox. Our client-side signature functionality is significantly more feature-rich than Microsoft's Outlook roaming signature feature. This means Exclaimer offers the most comprehensive range of email signature management solutions available.

The benefits of choosing Exclaimer

Exclaimer email signature software comes with many benefits over Outlook roaming signatures including:

Signatures on all devices

Ensure all emails get a high-quality signature added using the server-side functionality of Exclaimer. Emails sent from mobile phones are typically plain text by default. However, Exclaimer will convert these emails into HTML, automatically adding an HTML signature to all mobile emails.

Manage signatures online

Access and update your signature templates from the Exclaimer web portal, even if you're not in the office or working remotely.

Drag-and-drop signature editor

Easily create various template designs using our drag-and-drop signature editor. In other words, you don't need any HTML skills, and updates can be made in minutes.

Additional user access

Give ownership of email signature design and management to non-IT teams like the marketing department.

Signature folders

Separate templates into different folders, ensuring signatures are only applied to the correct users. In addition, you can also restrict user access so they can only amend specific signatures within certain folders.

Mac functionality

Use the client-side functionality of Exclaimer, which supports Outlook on Mac, Outlook on PC, and OWA.

  1. IT has to send the template out to each user, which is then manually added to their Outlook client.

  2. Using server-side ensures signatures cannot be modified and are added after any email is sent.

  3. IT can create a standard template, but the end user can still modify this.

  4. Updates can be done in minutes and are deployed in real-time.

  5. IT has to update the email signature template and send it out to every user. This request can easily be ignored.

  6. End-users can still modify their signatures on Outlook on Windows only.

  7. Full drag-and-drop editor and pre-built template library.

  8. Either manually create a signature in Outlook (rich) or email all staff the HTML to add to their Outlook installs.

  9. The user must select it manually - it cannot be automated.

  10. A signature will only be added in the message format.

  11. Would require manual selection each time - no automation.
