Every signature, one click away right inside Outlook
The WeLink add-in lets each team member pick the right signature while composing — in New Outlook for Windows and Mac, classic Outlook and the web. No copy-paste, no manual setup on each workstation.

Outlook add-inBuilt for the people who actually send the email
Server-side rules are great for enforcement — the add-in is where each person stays in control, message by message.
Per-user, per-message control
A panel built into Outlook lets each team member pick the right signature exactly when they compose or reply — no copy-paste, no IT ticket. The choice is theirs, every message.
Multiple signatures
Offer several approved signatures per person — corporate, sales, event — and let them switch in a click.
Remembered default
The last choice is kept per mailbox, including shared mailboxes and delegations, so the right signature is pre-selected next time.
Reorder & hide
Each user arranges their own list and hides the signatures they never use. Preferences are saved.
Per-template language
When a template is translated, the signature renders in the language the team member picked — no duplicate templates.
Real-size preview
Every available signature shows a true-to-size preview before insertion, so there are no surprises.
Multi-mailbox & shared
The add-in detects every accessible mailbox — shared boxes and delegations included — and applies the right signature to each.
Pops up on compose
Event-based activation surfaces the panel automatically when a new message opens, and can clear the native Outlook signature so only WeLink shows.
Works where desktop-only methods stop
Transport rules and mailbox configuration cannot theme New Outlook the way users expect. The add-in does — across every modern Outlook surface.
New Outlook for Windows
Full support for the rebuilt Windows client, where classic signature scripts no longer apply.
New Outlook for Mac
Reaches the modern Mac client too — a surface most server-side methods simply cannot style.
Classic Outlook & web
The same add-in covers classic Outlook desktop and Outlook on the web, for one consistent experience.
Live in minutes, not migrations
No software to package, no GPO. Enable the add-in once and your team is ready.
Admin enables the add-in
Deploy WeLink to your organisation from the Microsoft 365 admin center — once, centrally.
The panel appears in Outlook
Team members get the WeLink panel automatically when they compose a message.
Pick a signature
One click inserts the right, on-brand signature — in the chosen language.
It is remembered
The default is kept per mailbox, so the next message is ready instantly.
Use both — they are complementary
Many teams pair the add-in with server-side rules: per-user control where it matters, automatic enforcement everywhere else.
Outlook add-in
Per-user, per-message choice with multi-signature, remembered defaults and per-template language. Best when people need to pick the right signature themselves.
Server-side deployment
Transport rules, mailbox configuration or EWS append signatures organisation-wide with no install — across every mail client.
See all Microsoft 365 deployment methodsQuestions about the add-in
Which versions of Outlook are supported?
New Outlook for Windows and Mac, classic Outlook for Windows and Mac, and Outlook on the web. The add-in adapts its insertion method to each client.
Do users have to install anything themselves?
No. An administrator deploys the add-in once from the Microsoft 365 admin center, and it appears for everyone — nothing to install per workstation.
Can people choose between several signatures?
Yes. Each person sees every signature they are allowed to use, can reorder and hide them, and the add-in remembers their default per mailbox.
Does it work with shared mailboxes?
Yes. The add-in detects shared mailboxes and delegations and keeps a remembered default for each one.
How is it different from transport rules?
Transport rules append a single signature server-side for enforcement. The add-in gives each user control per message and reaches New Outlook — many teams use both together.
