Supplemental Anouncement:
Update 25-january-2023: Starting in February 2023 Microsoft will start enforcing hard limits in SharePoint Online when creating new SubSites, lists and libraries in a Site Collection to overcome their growing performance challenges. See Microsoft Message Center MC405984 (only visible to Microsoft365 Administrator accounts or see our FAQ)

To see how this may impact your (future) deployments

The enforced limits are:

- 2000 SubSites per Site Collection
- 2000 lists and libraries per SubSite.

This means our customers (unless they exceed the 2000 UCC A Unified Contact Center, or UCC, is a queue of interactions (voice, email, IM, etc.) that are handled by Agents. Each UCC has its own settings, IVR menus and Agents. Agents can belong to one or several UCCs and can have multiple skills (competencies). A UCC can be visualized as a contact center “micro service”. Customers can utilize one UCC (e.g. a global helpdesk), a few UCC’s (e.g. for each department or regional office) or hundreds of UCC’s (e.g. for each bed at a hospital). They are interconnected and can all be managed from one central location.'s in a single Site Collection) can continue using the below mentioned "Legacy" model of our Ucc.Creator (albeit with the extra parameter -UseSubsites when running the .ps1 scripts).

Secondly and separate from the above hard limit enforcement, there is also a recommendation by Microsoft to eliminate the use of SubSites altogether to improve on SharePoint performance and as they state: "each unit of work should get a separate site collection". This will not yet be enforced by Microsoft by February 2023, but may be at a later date. (with SubSites disabled, grouping different Site Collections together for functional and/or administrative reasons (which for UCC's is a common practice), Microsoft already suggests to prepare/use Hub Sites.

Anywhere365, a consumer of subsites, lists and libraries, has prepared for both the recommendation and limits and has made adaptations on their UCC Site Creator tool:

Starting with Ucc.Creator the default behavior is that every new UCC (Site) will be built in its own Site Collection (root site) without the necessity, or even option, for subsites (because this may already have been disabled by your administrator or tenant subscription if you need to adhere to Microsoft’s recommendation).

It is also still possible to work with SubSites enabled and use our new Ucc.Creator in a Legacy SubSite model with an additional parameter for the .ps1 scripts (-UseSubsites).

Due to the new insights on Microsoft's approach to hard limit enforcement, what previously we called "Preferred" model is now renamed to "OneUCC" model.
