Issues with the icons for our Microsoft Teams integration

Hi @Noelia Baquero

Thank you for sharing your concern. 

Looks like this issue may be related to Teams rendering the same icon assets across multiple surfaces. Microsoft’s design guidance shows that app icons can appear in several places, including app-related views and bot-related views.  

Based on my research, the app package should include two PNG icons referenced by the manifest: a color icon and an outline icon.  The color icon should be 192 × 192 px, and Microsoft recommends keeping the main logo within the 120 × 120 safe area, keeping the asset as a full square, and not applying rounded corners manually because masking is handled by Teams.  For the outline icon, Microsoft documents a 32 × 32 px transparent PNG, and the outline or border should be white. The guidance also states that the outline icon should not include extra padding around the symbol.

Because these same icon assets can appear across multiple Teams and Microsoft 365 surfaces, one possibility is that the uploaded files may not fully match the documented size, transparency, padding, safe-area, or manifest reference requirements.  

As a quick check, you could try to verify the icon files and the manifest first to ensure they meet the documented formatting requirements. If those are correct, please also confirm that the manifest references the correct icon file names and paths, and that the icons were included correctly in the app package. Additionally, the manifest and icons must be packaged together for Teams. 

I hope this helps.
