Built for the Microsoft 365 stack
Leave management that fits Microsoft 365
One Microsoft sign-on, a Teams bot for requests and approvals, and time off that lands in Outlook calendars — so leave lives inside the tools your team already opens every day.
If your company runs on Microsoft 365, leave tracking shouldn't mean a separate login, a separate calendar and a separate place to chase approvals. Absenca plugs into the three parts of M365 your team touches most — sign-in, Teams and Outlook — so booking and approving time off happens without leaving the Microsoft world.
People sign in with their existing Microsoft account, request and approve leave inside Teams, and see approved absences in Outlook. Underneath it's a full leave tracker — accruals, carry-over, public holidays per office and reports — so the convenience never costs you accuracy.
One Microsoft sign-on
Staff sign in with their existing Microsoft 365 / Entra account — no new password to set, forget or reset. SSO keeps access tied to the accounts IT already manages.
Teams bot for requests
Employees book time off and managers approve it from an actionable card inside Microsoft Teams, without opening another app or inbox.
Outlook calendar sync
Approved leave flows into Outlook and Microsoft 365 calendars, so a colleague's day off shows up next to the meetings you're scheduling.
Shared org calendars
Publish a who's-off feed your whole team can subscribe to in Outlook, alongside an .ics feed for anything that reads calendars.
Sign in once, with the account you already have
Connect Microsoft as a sign-in method and people log in with their existing Microsoft 365 account — the same one they use for email and Teams. There's no separate Absenca password to provision or reset, and access follows the accounts your IT team already controls.
Email/password and Google sign-in stay available too, so a mixed organisation isn't forced onto one identity provider. SSO is the default for Microsoft shops; it isn't a lock-in.
Requests and approvals in Teams, calendars in Outlook
The Teams bot handles the day-to-day: an employee picks dates and sees their balance, the request lands with their manager as a card, and a tap approves or declines it. The balance, the shared calendar and everyone's view update instantly.
Approved leave then syncs to Outlook and Microsoft 365 calendars — individual time off and a shared org-wide who's-off calendar — so the people scheduling meetings can see who's away without checking a second tool. Public holidays for 190+ countries apply per office, so a week off over a holiday is still counted correctly.
A full leave tracker behind the Microsoft front door
Teams and Outlook are the surface; the engine is a complete leave and absence system. Accruals, carry-over caps, seniority entitlements, blackout periods, half-day and hourly leave, TOIL, attachments and Bradford Factor analytics all run as normal. Admins manage policies and reports from the web dashboard, while everyone else barely leaves Microsoft 365.
Because Absenca is a focused leave tool — not a full HRIS bolted onto payroll — it's quick to set up and works happily alongside whatever HR system your Microsoft stack already includes.
