Microsoft does not offer on-premises deployment. If data residency and self-hosting are requirements, Mattermost is the appropriate alternative."},{"question":"Is Mattermost compatible with Microsoft Office files?","answer":"Mattermost can preview Office files (.docx, .xlsx, .pptx) through integrations but does not have native collaborative editing like Teams does with Office 365. For organizations requiring real-time co-authoring of Office documents, Teams is superior."},{"question":"What's the total cost difference for a 500-person company over 3 years?","answer":"Teams: $72,000-225,000 (at $4-12.50/user/month). Mattermost self-hosted: minimal cost (infrastructure only, estimated $15,000-30,000 for IT ops). Mattermost managed cloud: $58,500. Self-hosted Mattermost saves 70-80% but requires IT resources."},{"question":"Which is better for healthcare/compliance requirements (HIPAA, FedRAMP)?","answer":"Mattermost is superior for compliance because self-hosting gives full control over data location, encryption, and audit trails. Teams requires trusting Microsoft's compliance certifications and data residency offerings, which are limited to a few regions."},{"question":"Can I switch from Teams to Mattermost without losing message history?","answer":"Message migration is possible but requires technical work—Teams' export functionality is limited, and manual migration scripts are needed. Mattermost provides some import tools, but expect 10-20 hours of IT effort for 1,000+ users. Most organizations run parallel systems during transition."}],"faqPageSchema":{"@context":"https://schema.org","@type":"FAQPage","@id":"https://www.aversusb.net/compare/microsoft-teams-vs-mattermost)#faq","url":"https://www.aversusb.net/compare/microsoft-teams-vs-mattermost)","inLanguage":"en-US","name":"Microsoft Teams vs Mattermost — FAQ","description":"Frequently asked questions about Microsoft Teams vs Mattermost","dateModified":"2026-07-07T09:44:30.099Z","author":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B"},"publisher":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B"},"isPartOf":{"@type":"Article","@id":"https://www.aversusb.net/compare/microsoft-teams-vs-mattermost)#article"},"license":"https://creativecommons.org/licenses/by/4.0/","speakable":{"@type":"SpeakableSpecification","cssSelector":["#faq",".faq-item"]},"mainEntity":[{"@type":"Question","name":"Can I self-host Microsoft Teams on my own servers?","acceptedAnswer":{"@type":"Answer","text":"No, Microsoft Teams is cloud-only (SaaS) and cannot be self-hosted.
