Benefits of Microsoft 365 for Email Signatures

Azure AD User Data

Exchange Online transport rules provide a native (though limited) option for appending disclaimers and basic signatures.

Compliance Support

Microsoft 365's compliance center helps ensure email communications and signatures meet regulatory requirements.

Frequently Asked Questions

How do I manage email signatures in Microsoft 365?
You can set signatures individually in Outlook, use Exchange transport rules for basic disclaimers, or use a centralized platform like Siggly for rich, branded signatures deployed across the organization.
Does Outlook support HTML signatures?
Yes. Outlook desktop, Outlook on the web, and Outlook mobile all support HTML signatures. However, Outlook desktop uses the Word rendering engine, which has quirks with certain CSS properties.
Can I set different signatures for different departments?
Not natively with Microsoft 365 alone. Siggly supports rule-based signature assignment, allowing different templates for departments, offices, or roles based on Azure AD attributes.
What is the difference between Microsoft 365 and Office 365?
Microsoft 365 is the current branding that includes Office 365 services plus additional security and compliance features. Office 365 plans still exist but are being consolidated under the Microsoft 365 brand.
