Have a suggestion for improving Office 365? Let us know! Provide feedback here

With every subscription of Office 365 operated by 21Vianet, 21Vianet support provides technical, pre-sales, billing and subscription support. Support is available both online through the Office 365 operated by 21Vianet portal, and by telephone for both paid and trial subscriptions.

Authorized administrators can use the Office 365 operated by 21Vianet portal to submit service requests online and access support telephone numbers. For instructions, see Contact support.

The 21Vianet Office 365 technical support team troubleshoots only those issues that are related to Office 365 operated by 21Vianet. Issues that originate in customer networks fall outside of the Office 365 support boundaries, and in these cases, customers must work with their networking team for assistance.

Community and self-service support options

Self-service support is available for all Office 365 operated by 21Vianet users, and includes troubleshooting tools and videos, help articles and videos, as well as forums and wikis in the Office 365 community. For more self-help resources, see Learn about Office 365 operated by 21Vianet.

Pre-sales support

Pre-sales support for Office 365 operated by 21Vianet provides assistance on subscription features and benefits, plan comparisons, pricing and licensing, and helps to identify the right solution to meet your business needs.

Pre-sales support can be accessed using the same phone number as with technical support. For instructions, see Contact support.

Billing and subscription management support

Assistance for billing and subscription management issues is available online or by telephone during China business hours (Beijing Time), Monday through Friday. Billing and subscription management support can be accessed using the same phone number and online service request process as with technical support. The support telephone number can be found on the Office 365 operated by 21Vianet portal. For instructions, see Contact support.

Here are some examples of billing and subscription management issues:

  • Signing up for a trial or purchasing a subscription
