Finally, a Simple Way to Put Company Holidays on Every Calendar

Every IT team has heard the same story: “I showed up for work today and it was a holiday.”
The problem is simple - Microsoft 365 doesn’t provide an easy, centralized way to push company holidays directly onto every user’s calendar.
The normal workaround is to create a shared mailbox calendar just for company holidays. But that approach has flaws. Employees have to add the shared calendar manually, and if they remove it from their view, they lose visibility. That leads to missed days, confusion, and frustrated staff.
A Smarter Approach with Microsoft Graph
That all changes today. By leveraging App Registrations and Graph API permissions, we can streamline company holidays across your entire organization with one simple process.
Here’s how it works:
Set up the foundation
We guide your company through configuring an App Registration with the proper Graph API permissions. This gives us secure access to manage calendars across the tenant.
Build your holiday list
We compile your company’s holidays. You can provide a stand-alone list, or we can connect to your existing shared holiday calendar.
Push holidays to every calendar
With our program, we can either import holidays directly into each user’s calendar or use a script that pulls events from your shared holiday calendar and copies them across to every employee.
The result is a fully automated process that ensures every user always has the correct holiday schedule on their calendar — no more missed days or guesswork.
Why it Matters
Centralizing holiday schedules might seem small, but it has a big impact on productivity and employee experience. Instead of wondering if today is a holiday, your workforce gets clarity right in their Outlook calendar, synced across devices.

Bottom Line
Managing holidays in Microsoft 365 has always been clunky. We’ve fixed that. With our streamlined approach using Graph API, you can keep your workforce informed, aligned, and stress-free.
