Your interviews live in the ATS, your availability lives in Outlook

Most recruiting teams run on Microsoft 365. The pipeline sits in your ATS, but every interviewer's real availability sits in Outlook.

So you bridge the two by hand. You open three calendars in another tab, propose a time, find out someone was already booked, and the slot you finally land never makes it back onto the candidate record.

Connecting Outlook Calendar to your applicant tracking system closes that gap. Booking happens against live Outlook availability, and the interview is logged the moment it is set.

What connecting Outlook Calendar to 100Hires gives you

100Hires connects to Outlook Calendar for Microsoft 365, so availability checks, calendar invites, and interview sync all happen inside the candidate record. No separate booking tool and no manual loop back into the ATS.

It is the same approach we take to recruitment automation across the pipeline. Set the interview once and 100Hires handles the invite, the sync, and the timeline entry.

Works with Outlook Calendar for Microsoft 365 and Outlook email out of the box. See all integrations.

100Hires availability schedule setting the weekly hours when interviews can be booked

Stop double-booking your interviewers

Set the hours your team takes interviews and 100Hires only offers candidates times inside that window. On top of that it reads free/busy from every connected Outlook calendar, so anything marked busy or out of office in Microsoft 365 drops off the booking page too. For panels, a live availability check spans the whole group.

  • Free/busy read from connected Outlook calendars
  • Busy and out-of-office times hidden automatically
  • Live panel availability across the group

Let candidates book straight into Outlook

Share a self-scheduling link and the candidate picks from the open times your team has in Microsoft 365. The calendar invite goes out to everyone and the interview syncs both ways.

It lands on the candidate record in the same step, so there is no copy-paste back into the ATS afterward. The links work like Calendly, except they live inside 100Hires next to the rest of your pipeline.

100Hires vs bolting a scheduler onto a typical ATS

A typical ATS can connect to Outlook, but the useful parts often need an extra tool or a higher plan. 100Hires keeps availability, self-scheduling, and sync on one connection, with the full ATS underneath.

What syncs between 100Hires and Outlook Calendar
You do this in 100Hires What happens in Outlook What lands on the candidate record
Schedule a 1:1 interview Calendar invite sent to interviewer and candidate Interview, time, and Zoom link on the profile
Schedule a panel One invite to the whole panel once you pick a free slot Shared interview entry plus evaluation form
Send a self-scheduling link Candidate picks an open slot, invite auto-created Booked interview logged automatically
Interviewer marks time busy or out of office That time disappears from the booking page Candidate never sees an unavailable slot
Reschedule or cancel Outlook invite updates for everyone Profile timeline reflects the change

You can attach an evaluation form to any interview at the scheduling step, so panelists know what to score before the call starts. It is part of how 100Hires handles interview scheduling end to end.

  • No admin app install required
  • Outlook email syncs from the same screen

Outlook Calendar integration FAQ
+ Which Outlook accounts does the integration work with?
It connects to Outlook Calendar for Microsoft 365, the work or school account behind Outlook and Office 365. A personal outlook.com mailbox is not supported, because the availability and invite features rely on a Microsoft 365 business account.
+ Does scheduling in 100Hires actually block the time in Outlook?
Yes. When you book an interview, 100Hires sends the calendar invite and the event appears on each interviewer's Outlook calendar. The sync runs both ways for scheduled interviews, so a change on one side shows up on the other.
+ Can a candidate self-schedule a panel where everyone has to be free?
Yes. Add every interviewer to the interview and 100Hires only offers the candidate slots where all connected Outlook calendars are free at the same time. No trading availability over email.
+ Will the integration respect times I have marked busy or out of office?
It does. 100Hires reads free/busy from each connected Outlook calendar, so anything you mark busy or out of office is removed from the candidate booking page automatically.
+ Can candidates reschedule or cancel without emailing me?
Yes. Every confirmation includes reschedule and cancel links. When a candidate picks a new time, the Outlook invite and the candidate record in 100Hires both update.
+ Does the same connection also sync my Outlook email?
Outlook email is a separate connect on the same Settings screen. Once it is on, emails you send from a candidate profile appear in your Outlook mailbox and replies sync back to the profile.
+ Which video meeting tool does 100Hires create?
100Hires auto-creates a Zoom meeting when you schedule an interview. Microsoft Teams meeting auto-create is not part of the calendar integration today, so teams that standardize on Teams add the meeting link manually.
+ Do I need a separate scheduling subscription like Calendly?
No. Self-scheduling links, panel availability, and calendar sync are built into 100Hires, so there is no extra booking tool to buy or wire back into your ATS.
