Delta Chat as a Linux alternative to Microsoft Teams (consumer version)
Updated
Our verdict
Delta Chat is not a direct replacement for Microsoft Teams (consumer version) for most team collaboration use cases. It works well for decentralized, privacy-focused messaging with end-to-end encryption and supports group chats, file transfers, and voice messages. However, it lacks built-in video conferencing, real-time screen sharing, and calendar integration. It suits individuals or small groups prioritizing autonomy and security over feature-rich collaboration tools. If your workflow depends on live meetings or integrated task management, Delta Chat will fall short.

Opening your Microsoft Teams (consumer version) files
Delta Chat can receive and open files sent from Microsoft Teams, as it supports standard file types. However, there is no direct import of Teams chat history, messages, or meeting artifacts. Files shared in Teams can be manually forwarded to Delta Chat contacts, but formatting or context may be lost. Delta Chat does not integrate with Microsoft 365 document formats or cloud storage, so accessing .pptx, .docx, or OneNote files requires external apps.

How to install Delta Chat on Linux
flatpak install flathub chat.delta.desktopFrequently asked questions
Can Delta Chat do video calls like Microsoft Teams?
No, Delta Chat does not support voice or video calls. It only supports text messaging, file transfers, and voice messages. For real-time audio or video communication, you’ll need a separate app like Jitsi or Matrix-based clients.
Do I need a special email provider for Delta Chat?
No, Delta Chat works with most standard email providers. However, some providers may block IMAP IDLE or have strict rate limits. Providers like ProtonMail (via bridge) or Fastmail work better than Gmail or Outlook.com.
Can I use Delta Chat alongside Microsoft Teams?
Yes, you can run both apps simultaneously. Delta Chat can handle private, encrypted messaging while using Teams for meetings and team collaboration. This hybrid setup works if you value privacy but must comply with workplace tools.
