Control disclaimers, legal details and signatures through one rule set with templates per language, instead of many individual transport rules.

Why Disclaimers in Exchange Online Quickly Become Confusing

Native Exchange transport rules are powerful but often lack clarity when requirements grow in the enterprise environment.

Individual Rules and Language Logic Grow Out of Control

The more departments, locations and languages are added, the faster the native rule set turns into a hard-to-maintain web of conditions. Each rule adds room for error.

Maintenance Effort and Governance Risks Increase

For every marketing campaign or legal change, IT must intervene deep in the Exchange configuration. Careless mistakes lead to disclaimers being triggered incorrectly or emails getting stuck.

How Conbool Replaces Rule Chaos with Central Control

Logical Policy Engine

Move away from static transport rules. Define templates once in the policy engine and apply them dynamically to groups, domains, or Active Directory attributes.

Multiple languages and companies

Manage templates per language side by side. Set up exceptions without duplicating the rule set for every company.

Delegated Administration

Separate technical control from content design. Let marketing banners be pushed by the marketing team without these people needing Exchange admin rights.

When Native Tools are Sufficient – and When Governance Makes More Sense

Looking at it soberly: native Exchange is completely sufficient for a single company with a static disclaimer and one language. Transport rules are made for this.

When You Reach the Limits of Exchange:

  • Many exceptions for subsidiaries or specific recipient domains.
  • The need for HTML responsive footers with dynamic AD attributes per department.
  • The wish to run marketing banners without giving the marketing team admin rights on the Exchange server.
This is exactly where Conbool provides the necessary scaling level.

The Trombone Mail Problem

A simple transport rule without exceptions appends the same large footer to every reply. After a few replies, the message consists mostly of stacked disclaimers.

The Rule Engine in Action

Anatomy of a message

Four building blocks, maintained separately.

Marketing maintains the campaign, legal the notice, IT the rules. Nobody touches anyone else's template, and a trade fair banner expires on its end date by itself.

  1. 1

    Always at the top. Room for an event or a notice about external senders.

  2. 2

    Signature

    Name, title, direct line and photo from the directory. Empty fields hide their line.

  3. 3

    Campaign

    Its own block with its own time window. It follows the block before it, at the top below the banner or at the bottom below the signature.

  4. 4

    Legal notice

    Legal details from the central company data, either right after the signature or after the whole thread.

Sent Items

Your own copy looks like the recipient's.

Exchange stores the copy when you hit send, before any server-side signature can be added. That affects every server-side signature, whichever the vendor. Conbool therefore adds the signature in the mailbox after delivery.

  1. 1

    Send in Outlook

  2. 2

    Exchange stores the copy in Sent Items, still without signature

  3. 3

    Conbool adds the building blocks and delivers

  4. 4

    The copy receives the same signature

The original is never deleted
Separate consent, apart from the connection
Only delivered messages are updated

Requires Microsoft 365 with a connected organisation and a separately granted consent. If the signature is inserted by the Outlook add-in, it is already in the copy while composing.

Frequently Asked Questions (Exchange Online)

How does the solution integrate into existing mail flows?
Through connectors in the mail flow: outbound messages pass through Conbool and receive their building blocks there before delivery.
Can we migrate existing Exchange transport rules?
Yes. The conditions of existing transport rules can be rebuilt as rules in Conbool. It is often worth cleaning up at the same time.
How does the interaction with S/MIME encryption work?
Messages that the sender has already signed or encrypted with S/MIME or PGP are not modified by Conbool, so the signature stays valid. They therefore receive no disclaimer.
Does the processing affect delivery speed?
The building blocks are inserted as the message passes through the gateway, after which it is delivered directly.
How are thread detection and deduplication technically solved?
Our engine analyzes the email body for specific patterns and markers. This allows us to detect if a disclaimer is already present or if it's a reply, reliably preventing 'trombone mails'.
Does the disclaimer also appear in Sent Items?
Not with Exchange transport rules: Exchange stores the copy in Sent Items before the rule applies, so the addition is missing there. Conbool can update that copy after delivery, so the sender sees the same message as the recipient. The feature is switched on explicitly and consented to separately; the original is not deleted.
