Management wants a standard company signature with logo and disclaimer on every outgoing email across 60 users. Setting it per person in Outlook does not stick and people edit theirs. Central way to enforce this?

Per user signatures never stay consistent, you want a server side rule.

Microsoft 365: Exchange admin center, Mail flow, Rules, new rule, Apply a disclaimer to the message. Paste HTML with your logo and disclaimer. It stamps every outgoing message centrally and users cannot remove it.

Limitation: the native disclaimer appends at the very bottom and users do not see it while composing. Fine for legal disclaimers, less pretty for full signatures.

Polished per user signatures with photos and dynamic fields pulled from the directory: a third party signature manager handles that better than native rules.

Mail flow disclaimer rule for the legal text, sorted in ten minutes across all 60. Solved.
