Conbool Disclaimer applies email signatures server-side – regardless of device, mail client, or operating system. Consistent, legally compliant, and without user intervention.
Centralized Email Signature: Server-Side on Every Device
When employees manage their own email signatures, the result is inconsistencies, missing legal disclaimers, and brand violations. Centralized, server-side email signatures solve this problem fundamentally: the signature is added on the server at send time – regardless of whether the email is sent from Outlook, a smartphone, or a web interface.
Why decentralized signatures fail
Decentralized Signature Management
When every employee sets up their own signature, dozens of variations emerge. Outdated phone numbers, wrong logos, and missing disclaimers are the norm, not the exception.
Missing Legal Requirements
Business emails require specific legal information depending on jurisdiction. If these are missing from the signature, companies face warnings and fines – especially when not all clients are correctly configured.
Employees Forget or Modify
New employees set up signatures incorrectly, existing ones change them at will. On mobile devices, the signature is often missing entirely. IT has no control over the outcome.
How centralized signatures work technically
Conbool Disclaimer applies signatures server-side – after the user sends the email, but before delivery to the recipient.
Server-Side Application
The signature is applied on the mail server, not in the client. No Outlook plugin, no GPO deployment, no dependency on local settings.
Device-Independent
Whether Outlook Desktop, Apple Mail, webmail, or smartphone – the signature is always applied identically because it is added on the server.
Tamper-Proof
Employees cannot modify, delete, or bypass the signature. What is defined centrally is applied centrally. Compliance is guaranteed.
Auto-Sync from AD/Azure AD
User data such as name, department, phone number, and job title are automatically synchronized from Active Directory or Azure AD. No manual updates required.
Mobile Compatible
Emails sent from smartphones often lack signatures. With server-side application, mobile emails also receive the complete, correct signature automatically.
Instant Rollout
New signatures or changes are active for all employees immediately. No waiting for client updates, no Outlook restart, no training required.
Why server-side beats Outlook templates
Client-based signatures have fundamental weaknesses. Server-side application eliminates them all.
No Client Plugin Required
Outlook plugins need to be installed, updated, and maintained. They frequently break with updates or new Outlook versions. Server-side signatures require no installation on the endpoint.
Works on Every Device
Outlook templates only work in Outlook Desktop. OWA, Apple Mail, Android clients, and third-party apps remain without a signature. Server-side captures every outgoing email.
No User Intervention Possible
With client signatures, employees can delete, modify, or replace the signature. With server-side application, this is technically impossible.
Transport Rules Instead of GPOs
The signature is inserted via Exchange Transport Rules or mail flow rules. This is more reliable than Group Policies and works in hybrid and cloud environments.
