Question 1

Is calendly worth it or can we just say 'what time works for you?'

Accepted Answer

The "what time works for you" approach to scheduling is free, requires no tool, and works fine for a meaningful number of scheduling situations. Calendly is solving a specific problem that arises when that approach becomes genuinely costly, and the decision about whether to use it depends on whether that problem describes your situation.

The problem Calendly addresses is the back-and-forth of availability negotiation. When two people with moderately complex calendars need to find a meeting time, the exchange of "I'm free Monday afternoon or Thursday morning" followed by "Thursday morning doesn't work, what about Friday?" followed by "Friday I could do 10 or 2" can consume four to six emails and a day or two of elapsed time. When that exchange happens at scale — a salesperson scheduling twenty discovery calls a week, a recruiter scheduling thirty candidate interviews, a consultant booking client check-ins across multiple time zones — the aggregate cost of that friction is real and measurable. Calendly replaces the negotiation with a link to an availability grid where the recipient selects a time that works, and the meeting appears on both calendars automatically with confirmation and reminder emails sent without any additional action.

The product connects to calendar systems — most commonly Google Calendar and Microsoft Outlook/Exchange — and reads your existing events to determine when you are actually free, then surfaces only those open slots to invitees. This means the recipient cannot accidentally book during a time you are already committed, which is the failure mode of the manual "what time works for you" approach when the respondent suggests a time that conflicts with something the requester forgot to mention. Time zone handling is automatic, which matters considerably for distributed teams or external-facing roles where the other party is in a different region.

Beyond individual scheduling links, Calendly at higher plan tiers supports round-robin booking where multiple team members can receive bookings and they are assigned in rotation, team-based scheduling where invitees book with the right person based on routing rules, and collective scheduling where a meeting requires multiple hosts to all be available simultaneously. These features address scheduling problems that are genuinely complex enough that the manual "what time works" approach breaks down entirely — how do you manually manage round-robin assignment across a sales team of six without a tool?

The tool is not necessary for people who schedule infrequently, who work with a small set of recurring contacts who already know each other's rhythms, or whose meetings are so variable in format that a fixed-duration booking link would feel impersonal or misrepresent the nature of the conversation. The informal email exchange is appropriate in those contexts, and imposing a scheduling tool where the relationship warrants a more personal exchange can feel transactional in ways that undermine the relationship rather than serving it. The decision is really a question of scheduling volume and complexity: below a certain threshold, the tool adds more overhead than it saves; above it, the efficiency gain is clear.

Question 2

Does calendly work with google calendar and outlook or only one?

Accepted Answer

Calendly's calendar integrations are one of its core functional features and are generally reliable, though the behavior and features available depend on which calendar system you connect and which Calendly plan you are on.

For Google Calendar, the integration works through an OAuth connection where you authorize Calendly to read your calendar events and write new meetings to your calendar. Once connected, Calendly checks your Google Calendar for existing events and marks those times as unavailable in your booking page. When someone books a time through your Calendly link, the meeting appears automatically in Google Calendar with the invitee's name, the meeting type, and any information they provided during booking. The connection handles time zone translation, so if you are in New York and a London-based invitee books a slot, the meeting appears at the correct local time for each party without manual adjustment.

For Microsoft Outlook and Office 365, the integration connects through Microsoft's calendar API and works similarly — Calendly reads existing calendar commitments to block those times, and bookings create calendar events that appear in Outlook. The Exchange integration for enterprise accounts with on-premises Exchange servers rather than cloud-hosted Office 365 has historically had more variability in its setup requirements, and the specific configuration depends on how the organization's Exchange environment is set up. Teams using Exchange in a corporate environment should verify that the organization's IT configuration allows the OAuth connection that Calendly requires.

One detail worth understanding is the difference between calendar reading and calendar writing. Calendly by default reads events on the calendars you specify to determine availability but creates new meeting events on a single designated calendar. If you maintain multiple calendars — personal and work, for instance — you can typically configure which calendars Calendly checks for conflicts and which calendar new bookings are added to, though the specific options depend on the plan tier.

Calendly also supports a two-way sync in the sense that if you manually add a new event to your calendar after configuring Calendly, that event will be recognized as a conflict and block off that time for new bookings without requiring any manual update in Calendly. The availability shown to invitees reflects your live calendar state rather than a snapshot taken at setup, which means the integration stays accurate as your calendar changes throughout the day and week.

For teams using both Google Calendar and Microsoft Outlook — common in hybrid environments or when integrating with external partners — Calendly on paid plans supports connecting multiple calendar systems to a single account, which handles the availability checking across both environments. The specific behavior of multi-calendar connections and the plan tier required for them is worth verifying against current Calendly plan documentation, as the features at each tier have changed over time.
