    About .office domain

    .office is a brand TLD (dotBrand gTLD) delegated through ICANN's 2012 New gTLD Program. Microsoft Corporation serves as both the applicant and the registry operator for this extension. The string was delegated to the Root Zone on 23 June 2015, following a period of delayed progression due to name collision issues that required additional ICANN mitigation review before delegation could proceed. As a brand TLD, .office exists primarily to support Microsoft's brand integrity and provide a controlled, authenticated namespace for its products and services.

    Who can register .office domain

    Registration of .office domain names is strictly restricted to Microsoft Corporation and its wholly owned subsidiaries. This is not an open or commercially available TLD — no third-party individuals, businesses, or organizations are eligible to register names under this extension. There is no public registration path, no accredited registrar channel, and no application process available to outside parties.

    How to register .office domain

    Because .office is a brand TLD reserved exclusively for Microsoft Corporation and its wholly owned subsidiaries, it is not available through commercial registrars or any public registration system. All domain names under this extension are allocated internally by Microsoft acting as its own registry. Registrations are issued only to Microsoft entities, and the registry exists to serve brand protection and authenticated product delivery rather than public domain sales. There is no application, checkout, or DNS configuration process available to outside registrants.

    Typical uses of .office domain

    The .office extension is used exclusively within Microsoft's own ecosystem to support the Microsoft Office brand and its associated products and services. Domains under this TLD are deployed to create secure, authenticated web presences tied directly to Microsoft Office software, services, and platforms — helping users identify genuine Microsoft properties with confidence. Because the namespace is entirely controlled by a single corporate registry, every .office domain signals an official Microsoft-operated destination, making it a trust and brand-integrity tool rather than a general-purpose web address.

    Tips for registering .office domain

    • This TLD is not available for public registration at any price point — no registrar offers .office domains to external customers, so no budget or renewal planning is needed.
    • Because Microsoft controls all registrations internally, there are no third-party WHOIS privacy, transfer lock, or redemption period policies that apply to outside registrants.
    • Premium domain availability is not a relevant consideration, as the entire namespace is reserved for a single corporate entity.
    • No dispute resolution process (such as UDRP) is practically applicable to outside parties, since no external registrant can hold a .office domain to begin with.

    Frequently asked questions about .office domain

    Who operates .office domain?The registry for .office domains is Microsoft, administered by Microsoft Corporation.
    Who can register a .office domain?

    .office is exclusively available to Microsoft Corporation and its wholly owned subsidiaries — there are no eligibility pathways for any other entity, regardless of industry, location, or trademark ownership. No documentation, application, or fee structure exists for outside parties because the TLD was designed from the outset as a closed brand registry. If you encounter a .office domain in the wild, it is operated directly by Microsoft.

    Can I transfer a .office domain between registrars?

    Inter-registrar transfers for .office domains are not applicable in the conventional sense, as there is no public registrar channel through which these domains are sold or managed. Because all registrations are held internally by Microsoft, the standard EPP transfer process used for commercial TLDs does not apply to outside parties. Domain management within this namespace is handled entirely by the registry operator itself.

    Can I register a .office domain to promote my own office-related business?

    No — despite the generic appearance of the word "office," this TLD is a brand extension reserved solely for Microsoft's internal use. It is not a descriptive or open TLD like .shop or .services. Businesses in office-related industries have no route to register under this extension and should consider alternative TLDs for their branding needs.

    Does UDRP or any trademark dispute policy apply to .office domains?

    Because .office is a closed brand TLD with no external registrants, traditional UDRP or URS dispute mechanisms have no practical application — there are no third-party registrations that could infringe on a trademark holder's rights within this namespace. All domains are held by a single corporate entity, which eliminates the registrant-versus-complainant dynamic that dispute policies are designed to address. Trademark holders concerned about the .office string itself would need to engage ICANN processes rather than standard domain dispute forums.

    Was the .office application contested during the ICANN New gTLD process?

    The .office application did not face a contention set from competing applicants, but it did encounter a significant procedural delay related to ICANN's name collision assessment in late 2013. ICANN identified .office as one of 25 strings ineligible for an expedited alternative delegation path, meaning Microsoft had to wait for additional mitigation research before the string could proceed. This delayed delegation until June 2015, roughly three years after the original application was submitted in 2012.
