Why Microsoft integration is crucial
absentify was developed specifically for Microsoft 365 and integrates seamlessly into your existing system. This allows you to manage absences right where your team already works—in Teams, Outlook, and the Microsoft calendar.

Report or approve absences directly
Microsoft Outlook
Calendar automatically synchronized
Single Sign-On
Secure login with your Microsoft account

Register once – sync everywhere
Whether it's a personal calendar, team calendar, or Teams channel: absentify keeps all calendars automatically updated, so your team always knows who is available.
Absences automatically appear in the calendar
As soon as a request is created or approved, absentify automatically enters the absence into the personal Outlook calendar. Status changes such as “Pending” or “Absent” are updated in real time. Employees do not have to maintain anything, make any manual adjustments, or enter anything twice.
Automatic entries & status updates

Departments & locations always up to date
absentify can automatically enter absences into any shared Outlook calendar.
This allows teams, locations, or entire departments to immediately see who is present—without HR or team leads having to manually maintain calendars.
Perfect for team and location calendars
Name, period, and type of absence visible
Fully automatic updates when changes are made

Microsoft Teams: Absences directly in the Teams channel
Assign a department to a Teams group, and absentify will automatically synchronize all absences in the group calendar.
This allows every team member to immediately see who is absent in the channel without having to open Outlook.
The same absence appears simultaneously in Outlook, Teams, Shared Calendars, and optionally as an iCal feed in external calendars.

Answers to the most important questions
Here you can find concise answers to common questions about usage, security and functions.
What happens if the Microsoft connection is interrupted?
Absentify automatically attempts to reestablish the connection. Administrators are notified if automatic restoration is not possible.
Can I have different shared calendars for different departments?
Yes! You can create as many shared calendars as you want and assign each department its own calendar.
Are holidays also synchronized?
Optionally, yes! You can create holidays as special “absences,” which will then also be synchronized.
Does synchronization also work with Exchange On-Premise?
Synchronization works best with Microsoft 365 / Exchange Online. For Exchange On-Premise, the iCal integration can be used.
How many shared calendars can I synchronize?
That depends on your plan. With the Plus plan, you can synchronize an unlimited number of shared calendars.
What happens if an employee manually changes their calendar in Outlook?
Synchronization is unidirectional (absentify → Outlook). Changes in Outlook do not affect absentify. The next sync from absentify will overwrite manual changes.
Can employees disable synchronization?
Yes, employees can disable calendar synchronization in their personal settings if they wish.
Do I have to set something up for each employee?
No! Synchronization is fully automatic. As soon as an employee is created in absentify and enters an absence, it is automatically synchronized in Outlook.
