Terms of Service


Terms and Conditions

  • What is SingTel ONEOffice?
    SingTel ONEOffice is a next –generation service which features a suite of collaboration tools which runs on the web browser without having to install a client.
  • What do I need to do to setup ONEOffice?
    You do not need to worry about the setup as this service is included when you purchase the solution. The one-time setup includes assisting customers to update the CNAME & MX records with your domain provider, creating up to 5 users and assigning licenses, updating the POP/IMAP password and configuring ONEOffice on email clients. You can use the solution immediately when the setup is completed.
  • How does ONEOffice work?
    ONEOffice is a web-based hosted solution, which means you can access ONEOffice at anytime, anywhere you have an Internet connection. This technology is referred as "Software-as- a service" in which IT applications are provided "as a service", allowing users to access these applications from the Internet without needing to maintain the infrastructure that supports them.
    Since ONEOffice is web-based, your employees can be productive from anywhere, whether they're at their own desk, using a different computer, or on the go with a mobile device.
  • How is ONEOffice different from a free account?
    You may have had experience using many of these applications with your account, and while these applications are similar, ONEOffice solution for business has been enhanced with critical differences:
  • ONEOffice is for your business
    When you sign up for ONEOffice for your business, you sign up with your own company domain name. So instead of having a email address, you would create or maintain a company email address such as The admin in your company will be given rights to manage and control the user accounts across your company domain.
  • Enhanced business-oriented features
    These are the features available in ONEOffice that's not available in the free consumer applications:
    • ONEOffice Email: Saves all your corporate information with improved mailing list capabilities, and increased mail thresholds
    • ONEOffice Sites: Understanding that a company intranet and shared documentation is so critical to success, optimized to provide you with the right storage quotas to address your business needs
    • ONEOffice Calendar: Enables conference room and resources sharing, allowing you to schedule office conference rooms or other shared resources in your office.
    • ONEOffice eSMS: Usage based charges where you can send SMS to multiple recipients via your email account.
    • ONEOffice eFax: Wthout having to buy a physical fax machine, you can attach a file and just send a fax the same way as sending an email.
  • Why should I use ONEOffice instead of an on-premise mail solution?
    The reason why ONEOffice is a great alternative of a hosted solution to other alternate on-premise solutions is because:
    • Lower cost: ONEOffice is being delivered over the web at a fraction of the cost of installed systems. This means that ONEOffice can provide a significantly lower total cost of ownership (TCO). Mailbox redundancy, infrastructure upgrades and infrastructure scaling are all handled behind the scenes, so your business doesn't need budget time and money for these projects.
    • Higher quality: ONEOffice offers superior security, reliability, and storage space than most organizations can accomplish with an on-premises solution
    • Improved usability: ONEOffice provides the simple, intuitive interface so that there is minimal training resource for end-users.
    • Leader in Innovation: ONEOffice powered by Google continues to demonstrate its industry leadership in terms of web-based innovation. Driving this platform forward, Google has the leading computing platform and have assembled one of the strongest teams of computer scientists in the industry. As an ONEOffice customer, you get to experience that innovation first-hand as product enhancements are rolled out on a regular basis.

  • What is Google Cloud Connect?
    Google Cloud Connect is a plug-in for Microsoft® Office 2003, 2007, and 2010 that lets you share and simultaneously edit Microsoft Word, PowerPoint®, and Excel® documents with other people in your organization. You get the collaboration benefits of Google Docs, while continuing to use Microsoft Office.
  • How does Cloud Connect works?
    • Syncing and sharing documents: Google Cloud Connect tracks, manages, and syncs all changes on your Microsoft Office documents into one updated version for each document. Each document that you sync through Google Cloud Connect gets a unique URL, or web address, that you can share with collaborators through IM or email. Depending on the privacy setting you've selected for the document, other people will be able to click this link and view the document in the browser.
    • Collaborating simultaneously on documents: Google Cloud Connect for Microsoft Office lets you easily share documents with other people. When you add someone as an editor in a document, they receive an e-mail letting them know that a document has been shared with them. From there, they can open a link to view the document in the browser, or if they want to make edits, they can download the document and open it in Microsoft Office. When another editor edits a document in Microsoft Office, all changes get synced to and will be reflected on your screen.
    • Revision history: Using Google Cloud Connect, you can edit a document both online and offline. Every time you sync a document, the revisions of a document are stored so you can easily roll back to a previous version. You can retrieve and revert to any prior revision of a document at any time.
  • What are the system requirements for using Google Cloud Connect?
    Google Cloud Connect works for Microsoft Word, PowerPoint, and Excel files for users of Microsoft Office 2003, 2007, and 2010. It supports Windows XP, Windows Vista, and Windows 7. It is currently not available for Macs. For more details, see System requirements.
