Add an email signature in Microsoft 365 (roaming signatures)
Takes about two minutes. Where a step says to copy your signature, use the Copy signature button in Sigture's export dialog — or your personal signature page if your team sent you one.
- 1
Set the signature once in Outlook Web or New Outlook (see those guides).
- 2
Microsoft 365 stores it as a roaming signature attached to the mailbox.
- 3
It syncs automatically to New Outlook on every device you sign in to.
- 4
Classic Outlook users: paste once locally (roaming to classic is rolling out tenant by tenant).
Good to know
For company-wide rollout, prefer per-user install via this guide plus the Contacts + variables workflow — every employee gets a personalized copy of one master design.
