SummaryMicrosoft Office 365 does not require you to use WAN Optimization Controller devices (also known as WAN acceleration and caching devices), nor can we comment on the effectiveness of these solutions. Customers may decide to use such devices to increase performance under conditions of high latency or low bandwidth for Microsoft Exchange Online and Microsoft SharePoint Online. We advise customers to use their own discretion in deploying these devices with Office 365, whether in Multi-Tenant (MT), Dedicated (D), or ITAR service deployment configurations.
Microsoft does not offer first-party technical customer support for WAN Optimization Controller (WOC) devices. As with other network infrastructure equipment, we have not tested the use of these devices with Office 365 to make sure that they work, nor do we take any responsibility for making sure that they continue to work as part of regular service updates. Customers should work directly with their WOC vendors to receive technical support.
During support incidents, we do require customers to inform us if they are using WOC devices. We also require that customers have an easy way to bypass the WAN optimization service for Office 365. When we try to resolve a customer service issue in Office 365, we may ask that these devices be put in bypass mode before we continue with diagnosis and issue resolution. By bypass mode, we mean any combination of network or device configuration that logically or physically removes the device from the infrastructure path between the customer and Office 365.
More InformationOffice 365 Dedicated and ITAR customers may install and use WOC devices with the service at their own discretion. We do enable co-location of these devices in Microsoft data centers in which a customer's private network ends. Be aware that we enable this option only for Office 365 Dedicated and ITAR deployments, not for Multi-Tenant service. To realize the same benefits, some WOC vendors do offer the option to deploy only in the customer's data center, and they do not require co-location in a Microsoft data center. Because the use of WOC devices can potentially affect the reliability of the Office 365 service, customers must agree to the following when they opt to use these devices:
