Built for the Microsoft 365 stack
Leave management that fits Microsoft 365
One Microsoft sign-on, an email to the manager for every request, and time off that lands in Outlook calendars — so leave fits around the tools your team already opens every day.
Free for up to 10 people · 11 to 50 people: $37.50 a month on Pro
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 two parts of M365 your team touches most — sign-in and Outlook — so booking and approving time off fits around the Microsoft tools people already use.
People sign in with their existing Microsoft account and book leave in the web app. Their manager gets an email that links to the approval queue, approves it in one click, and the approved absence shows up 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.
What you get
One Microsoft sign-on
Staff sign in with their existing Microsoft 365 / Entra account — no new password to set, forget or reset. Microsoft sign-in keeps access tied to the accounts IT already manages.
An email for every request
Every request reaches the right manager by email, with a button that opens the approval queue, and a reminder follows if it sits unanswered. One click approves it.
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. Available on Pro and the Custom Pack, not on the free Starter plan.
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 Outlook. There's no separate Absenca password to provision or reset, and access follows the accounts your IT team already controls.
Email/password, Google and Slack sign-in stay available too, so a mixed organisation isn't forced onto one identity provider. Microsoft sign-in suits Microsoft shops; it isn't a lock-in.
Email alerts, calendars in Outlook
An employee books dates in the web app, and the request lands in their manager's inbox with a button that opens the approval queue. One click approves it; the employee hears back by email, and their 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
Sign-in 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 for everyone else leave shows up in the Outlook inbox and calendar they already check.
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.

Frequently asked questions
- Is there a Microsoft Teams bot?
- Not yet. Absenca's Microsoft Teams bot is built and coming soon, but it can't be installed today. Until then, Absenca works alongside Microsoft 365 through Microsoft sign-in and Outlook calendar sync, and leave synced to Outlook already shows up in the Teams calendar. People request and approve leave in the web app, and each new request's email links to the approval queue.
- Does Absenca support Microsoft single sign-on?
- Yes. Staff can sign in with their existing Microsoft 365 / Entra account, so there's no separate Absenca password to set up or reset. Email/password, Google and Slack sign-in remain available alongside it.
- How do managers approve leave?
- Each new request is emailed to the right manager with a button that opens the approval queue, where one click approves it. Every decision updates balances and the calendar automatically, and the employee gets the answer by email.
- Does approved leave show up in Outlook?
- Yes. Absenca syncs approved time off to Outlook and Microsoft 365 calendars, and you can publish a shared who's-off org calendar plus .ics feeds for anything that reads calendars.
- Do I need to use both Microsoft sign-in and Outlook sync?
- No. They're independent. Turn on Microsoft sign-on, Outlook calendar sync or both, whichever suits how your team works.
- Is the Microsoft 365 integration free?
- Microsoft sign-in works on every plan. Outlook calendar sync is on every plan, the free Starter plan included. Shared org calendars are on Pro and the Custom Pack, not on the free Starter plan. Absenca is free for up to 10 people. Pro is $37.50 a month for up to 50 people, or $33.75 a month billed annually ($405 a year).
