main entity: Can I self-host Microsoft Teams on my own servers?
  type: Question
  accepted answer: Answer
    text: No, Microsoft Teams is cloud-only (SaaS) and cannot be self-hosted. Microsoft does not offer on-premises deployment. If data residency and self-hosting are requirements, Mattermost is the appropriate alternative.
    language: en-US
main entity: Is Mattermost compatible with Microsoft Office files?
  type: Question
  accepted answer: Answer
    text: 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.
    language: en-US
main entity: What's the total cost difference for a 500-person company over 3 years?
  type: Question
  accepted answer: Answer
    text: 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.
    language: en-US
main entity: Which is better for healthcare/compliance requirements (HIPAA, FedRAMP)?
  type: Question
  accepted answer: Answer
    text: 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.
    language: en-US
main entity: Can I switch from Teams to Mattermost without losing message history?
  type: Question
  accepted answer: Answer
    text: 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.
