Using a Microsoft Teams Icon in an Email Signature

The short answer

A Teams icon in an email signature is usually a small image of the Microsoft Teams product logo, linked so recipients can start a chat, call or meeting with the sender. In practice, the icon that ends up in the signature should be a raster image, typically a PNG, not live vector artwork. Most email clients do not reliably display SVG, so even if you start from a vector file, what you place in the signature is an exported raster version. The logo also belongs to Microsoft, so permission to download a copy is not the same as permission to use, alter or recolor it.

What exactly is being discussed

Three different things often get called the Teams icon, and they matter differently here.

• The Microsoft Teams product logo: the trademarked mark Microsoft uses for the application.
• A vector source file of that logo, such as an SVG, EPS or PDF containing editable paths.
• A raster image of the logo, such as a PNG, made of a fixed grid of pixels. This is what an email signature actually displays.

In a signature, the image is a visual cue for a link, not a branding element of your own company. That role shapes both the technical choices and the permission questions below.

Vector artwork versus what the signature shows

Vector artwork describes shapes mathematically, so it can be scaled without losing sharpness and edited path by path. That makes it the right master format for a logo. An email signature, however, is HTML rendered by many different mail programs and webmail services, and support for SVG across them is inconsistent. A raster PNG with a transparent background is the dependable choice for display.

Two practical consequences follow. First, export the PNG from a clean source at a higher resolution than the size it will display, then constrain its displayed size in the signature, so it stays crisp on high-density screens. Second, do not judge a file by its extension. A file named with an SVG, EPS or PDF extension can contain only an embedded raster image wrapped in a vector container, with no editable paths at all. Open it in a vector editor and check whether the shapes are selectable paths before treating it as true vector artwork.

Permission: downloading is not the same as using

The Teams logo is a Microsoft trademark. Finding a downloadable copy, whether on an icon site or elsewhere, only tells you a file is available. It does not grant the right to use the mark in your communications, and it does not grant the right to modify it. Microsoft publishes trademark and brand guidelines that govern how its marks may be used; check the current version of those guidelines before adding the icon, rather than relying on a third-party download page's licence, which can only cover that site's own contribution, if any.

As a general principle with third-party marks, use the logo unaltered: keep the original colors, proportions and shape, avoid adding effects, and do not combine it with your own logo in a way that suggests endorsement or partnership. If your organisation has a legal or brand team, they are the right people to confirm whether a product icon is acceptable in staff signatures.

Preparing the icon for a signature

• Obtain the logo from an official Microsoft source where possible, and read the accompanying usage terms.
• If you have a vector file, confirm it contains real paths rather than an embedded image.
• Export a PNG with a transparent background at a higher resolution than its display size.
• Host the image somewhere reliable, or embed it as your signature tool requires, and set its display size in the signature.
• Link it to a valid Teams chat or meeting address for the sender, and add descriptive alt text so the link still makes sense when images are blocked.
• Test the signature in the mail clients your recipients are most likely to use, including with images turned off.

What this article cannot confirm

No specific evidence was available for this piece about Microsoft's current wording on product-icon use in signatures, official download locations, file specifications or recommended pixel dimensions. Those details can change, so verify them directly with Microsoft's published brand and trademark guidance and with your own email platform's documentation rather than treating any figure from a third party as authoritative.
