Connect your Exchange calendar to let Calendly check for busy times and add events automatically. Learn how to set up your Exchange connection.
Before you begin
Version & Server Information:
- Calendly supports Exchange versions 2013, 2016, and 2019.
- Your Exchange account must utilize an EWS connection. ActiveSync connections are not currently supported.
- If you are using Exchange via Amazon WorkMail, this endpoint acts on a version of Exchange that is not supported at this time.
- Exchange IMAP/POP connections are currently unsupported.
- If your Exchange calendar connection has a 2FA/MFA set up enabled, you will need to utilize our Microsoft Outlook Plug-In (for Windows users) instead.
Connect your Exchange Calendar
Go to Settings, then select Calendar.
In your Calendar settings, connect your calendar account:
- To connect your first calendar, select Connect next to Exchange Calendar.

Customize how Calendly uses your Exchange calendar
After you connect your Exchange calendar, you can manage how Calendly checks your availability and adds new meetings.
Calendars to check for conflicts
Calendly can only check your primary Exchange Calendar for conflicts. Calendly cannot check sub-calendars or shared calendars.
By default, Calendly will mark you as unavailable during events labeled as Busy, Tentative, and Away / Out of Office. You can choose to check or uncheck your primary calendar as needed. You'll always be marked as unavailable for busy events.
To change how the other statuses affect your availability, select the dropdown for What's considered unavailable? and uncheck any options you want Calendly to ignore.
If your event status in Exchange is set to Working Elsewhere, Calendly will treat you as available. The Working Elsewhere status is only available in Outlook on the web, not in the Outlook desktop app. If you view this event in the Outlook desktop app, it will show as busy, but Calendly will still treat you as available via the Exchange connection.
Calendar to add events to
Choose the calendar where Calendly should add new meetings. Calendly won't add events to any other calendar.
What to do if Calendly can't connect to your Exchange server
If Calendly can't connect to your Exchange server with only an email address and password, try the following options:
- Add your "Exchange server" in EWS URL format and leave Domain and Username empty.
- EWS URL format: https://mail.example.com/ews/exchange.asmx where "mail.example.com" is replaced with your unique server information.
Note: This URL is different than the one you normally use to access your email in the browser. How to find your Exchange Server. - If that doesn't work, try adding your Domain and/or Username. How to find your Exchange Domain and Username.

How Calendly stores your Exchange credentials
We take securing your credentials extremely seriously. Here's how.
- When you provide your login credentials to connect your Exchange calendar to Calendly, we send your email and password to our servers through an encrypted SSL connection.
- Once your credentials reach our servers, we encrypt them before storing them in our database. We store the encryption key as an environment variable on our servers, ensuring even more security.
- When we need to access your Exchange calendar, we decrypt your credentials in memory. We never store your decrypted credentials anywhere.
All of this ensures that your Exchange calendar credentials are safely stored using industry best practices.
