Rocket.Chat as a Linux alternative to Microsoft Teams (newer versions)
Updated
Our verdict
Rocket.Chat is a strong, self-hosted alternative for teams that prioritize data ownership and open standards. It covers core chat, video, and file sharing well. However, it lacks the deep Microsoft 365 integration, such as native Outlook calendar sync and Azure AD single sign-on, that many Teams users rely on. It is best for organizations willing to manage their own infrastructure or use Rocket.Chat’s cloud, and who do not need tight coupling with existing Microsoft enterprise tools.

Opening your Microsoft Teams (newer versions) files
Rocket.Chat does not natively open or export Microsoft Teams-specific file formats. It handles standard office documents (DOCX, XLSX, PPTX) and PDFs via its file viewer or by downloading them to edit in external applications. There is no direct migration tool to convert Teams chat history or file structures into Rocket.Chat; files must be manually re-uploaded or synced via API scripts.
Switching from Microsoft Teams (newer versions) to Rocket.Chat, step by step
- Deploy a Rocket.Chat server instance or subscribe to their cloud service
- Configure authentication using LDAP, SAML, or OIDC to match your existing identity provider
- Export necessary files and documents from Microsoft Teams storage
- Create channels and user groups in Rocket.Chat matching your team structure
- Upload shared files to the appropriate channels or use API scripts for bulk import
- Install desktop and mobile apps for all users and configure notification settings

Can Rocket.Chat integrate with my existing Microsoft 365 calendar?
Not natively. You will need to use third-party integrations or the API to sync events, but it is not as seamless as Teams' built-in Outlook integration.
Is Rocket.Chat free to use?
The software is free and open-source under the MIT license. You pay for hosting infrastructure if self-hosting, or for their managed cloud service if you choose that option.
Does Rocket.Chat support end-to-end encryption?
Yes, it offers end-to-end encryption for private channels and direct messages, which is a feature not available in standard Microsoft Teams configurations.
