MICROSOFT 365 EXTENSIONS

{{Extending Microsoft 365 with your own functions}}

We develop apps, add-ins and automation that extend Microsoft 365 with exactly the functions you are missing. You get more out of the licences you already own and stay in familiar surroundings.

THE SERVICE

Extending Microsoft 365 deliberately

We develop apps, add-ins and automation that fill exactly the gaps in Microsoft 365, so you get {{more out of the licences you own}}.

General
Deep dive
1

Needs analysis

We identify missing functions and fitting extension points in your Microsoft 365 environment.

Gap analysis, licence scoping, extensibility points, feasibility, prioritisation

2

Teams apps

Custom applications extend Microsoft Teams with functions for the way you work.

Teams Toolkit, tabs, bots, message extensions, adaptive cards

3

Office add-ins

Add-ins bring extra functions straight into Word, Excel and Outlook.

Office JS API, manifest, task panes, ribbon commands, web add-ins

4

SharePoint extensions

Bespoke components extend SharePoint pages with your own functions and views.

SPFx, web parts, extensions, application customiser, PnP framework

5

Low-code extensions

With the Power Platform, extensions arrive fast and stay low-maintenance.

Power Apps, Power Automate, Dataverse, custom connectors, Power Fx

6

Integration & operation

Extensions fit securely into existing licences and governance.

Entra ID, app registrations, Graph API, app permissions, ALM deployment

OUR APPROACH

Microsoft 365 extensions in five steps

1

Analysis

We identify the missing function and the fitting extension points.

1

Analysis

We run a gap analysis, review the functions already available through licence scoping and survey the extensibility points on offer. That evidences where an extension genuinely adds value.

You receive a named business gap with feasibility examined and priority set. This basis settles the fitting extension route of the next step.

2

Design

We settle the fitting extension route and the architecture.

2

Design

Against need and feasibility we choose the suitable extension route, for instance a Teams app, Office add-in, SharePoint component or low-code. The decision follows the extensibility points and what is reasonable to run.

You receive a reasoned solution route that fits the concrete use case. This design is the specification for the development in the next step.

3

Development

We build the extension inside the familiar Microsoft 365 setting.

3

Development

Depending on the design we develop the extension with the Teams Toolkit, the Office JS API, SPFx or the Power Platform with Power Fx. Adaptive cards, task panes, web parts or Power Apps bring the function straight into the tools people know.

Your teams carry on in familiar surroundings and receive the missing function exactly where it is needed. The extension developed is securely connected in the next step.

4

Integration

We connect the extension securely and with the right permissions.

4

Integration

We connect the extension through Entra ID, app registrations and the Graph API and grant app permissions on the principle of the least rights necessary. Established permission and management requirements remain decisive.

Users reach only approved content, and the environment stays consistent. The connected extension then passes into controlled operation.

5

Operation

We deliver the solution under control and tend it.

5

Operation

We roll the extension out through ALM deployment and plan updates and operation together with your owners. That way the solution keeps pace with changes to the platform and stays maintainable.

You receive an extension delivered under control that can be adapted or withdrawn as needed. Out of daily operation further gaps can be closed deliberately.

Frequently asked {{questions}}

FAQ

Answers to the questions we are asked most often about extensions for Microsoft 365.

What are extensions for Microsoft 365?
Microsoft 365 extensions are apps, add-ins and automation that extend your existing environment with exactly the functions missing from the standard. Instead of introducing additional silos, we extend familiar tools deliberately where your routines call for it. Your teams therefore carry on in familiar surroundings while getting more out of the licences you own. The benefit becomes tangible because the extension supports the concrete task.
When is an extension worthwhile over the standard?
An extension is worthwhile when a concrete business gap remains that cannot be closed sensibly with what is already on board. We first examine what the existing Microsoft 365 functions already cover and propose an extension only where it brings evident value. As criteria we use recurring need, tangible benefit and reasonable operation. We therefore avoid needless add-on solutions and start where impact and feasibility stand in the best ratio.
How do extensions get more out of the licences we already have?
More value arises by using the functions already licensed rigorously and extending them deliberately with the abilities that fit. We survey which building blocks of your Microsoft 365 environment are still unused and close the remaining gaps with apps, add-ins or automation. You therefore avoid parallel tools and extra contracts for functions that can be delivered inside the existing environment. That raises the value of the investment you have made and keeps the landscape clear.
How do extensions fit into our Microsoft 365 environment?
We develop and run extensions within the rules of your existing environment. In doing so we respect established permissions and management requirements, so users reach only approved content. Updates and operation we plan together with your owners, so the solutions stay maintainable and keep pace with changes to the platform. Your environment therefore stays consistent, and extensions can be delivered under control and adjusted again when needed.
How do we uphold security and control with extended functions?
We plan security and control in from the start. We establish which data an extension processes, who may reach what and how the usage can be traced, and align everything with your existing security and management requirements. Rights are granted on the principle of the least permission necessary. Concrete data protection and compliance requirements we examine individually in each context, in order to shape solutions that are solid and fitting.
