Since its introduction as part of the Office 365 enterprise offering (now Microsoft 365), SharePoint Online usage has skyrocketed. It was initially envisioned to be an entry-level document management system but has since expanded to provide a content management and content services platform, an intranet portal for enterprise information and applications, a groupware platform, a social platform, and a platform to develop custom web applications. Because of these expanding use models, many have found that the standard SharePoint storage allowance is not enough.
SharePoint Online allocates a quantity of storage that's based on the number of users. The included SharePoint Online storage allocation is 1 TB plus 10 GB per licensee. For example, a 1,000 user subscription for Office 365 and SharePoint Online would provide 11 TB of storage (1 TB + (.01 TB *1000 users)). This storage is included and available to all site collections in the Office 365 tenant and serves as a central pool from which everyone using SharePoint Online can draw. Once you reach your included SharePoint storage limit, additional storage is available. However, it’s expensive at $0.19 per GB, i.e., an additional TB of storage would cost an additional $190 per month.
There’s also an additional problem, specifically, SharePoint Online storage limitations. Microsoft limits the site collection that a SharePoint Online tenancy can have to 25 TB. When you reach that limit, you cannot buy any more SharePoint storage from Microsoft. So, what are your options?
At past Microsoft Ignite conferences, many attendees ask me if and how they can extend their SharePoint storage beyond the current 25 TB limit so they’re not forced to purchase additional (expensive) SharePoint Online storage. The frequency of this request suggests that many companies have already blown through the newly raised 25 TB SharePoint Online storage limit.
Microsoft has made provisions to allow SharePoint Online customers to purchase additional SharePoint storage for $0.19 per GB per month. As you may have noticed, this is well above the average price of standard cloud storage, so for some, it has limited their SharePoint plans. For example, a large SharePoint instance that consumes 25 TB of included storage and 15 TB of additional storage would cost an additional $34,200 per year in extra storage costs.

SharePoint customers I’ve spoken with have been contemplating two equally unappealing options: limiting individual SharePoint Online growth, or worse, purchasing additional SharePoint storage at a premium price. My response has been to offer a third option: extend your SharePoint Online storage beyond the 25 TB to another low-cost cloud repository, utilizing your company’s own Azure tenancy.
One thing to understand when considering Azure as a solution to extend SharePoint is that Azure, by itself, is a stack of services. Native Azure applications can take advantage of these services to create stand-alone applications that offer capabilities that would be impossible for third-party SaaS cloud providers to duplicate. A partial list of the related Azure services include:
Ideally, customers want to leverage their existing Microsoft cloud as a stable, secure, and efficient way to keep overflow SharePoint data available at the lowest possible cost, while enforcing their security protocols. However, while Microsoft Azure offers some of the lowest per GB pricing (on the “cool” tier), it is currently not set up to take and manage SharePoint overflow. To seamlessly utilize your company’s Azure subscription for additional, low-cost SharePoint storage, you must install a separate, native Azure SharePoint storage extension solution within your Azure tenancy.
For example, the “cool” Azure storage tier is a fraction of the cost of dedicated SharePoint Online storage – approximately 75% to 90% less. And while a third party application, designed to automatically extend SharePoint Online storage to your company’s Azure tenancy would add some costs, the total annual savings are still considerable.
The chart above lays out the costs for both SharePoint Online storage and that of Azure storage used for file extension.
As the graph above illustrates, once additional SharePoint Online storage extension requirements rise above 5 TB, the most cost-effective solution is a third party information management application running in your company’s Azure tenancy. The cost savings become much more significant with each additional 5 TB of storage.
One question all customers have is: what happens if and when SharePoint Online storage requirements shrink? Fortunately, the SharePoint Online storage extension - using your company’s own Azure tenancy, is automatically scalable so there is no need to actively manage the storage resources. In the future, if the need for additional storage is no longer needed, the additional SharePoint Azure storage will be automatically released, saving you the additional cost. Remember, with Azure storage; you only pay for what you use.
