Connecting Microsoft Exchange Calendar

meetergo connects to Microsoft Exchange 2013, 2016, 2019 and newer on-premises versions. Within minutes your appointments sync and bookings go straight into your Exchange calendar.

We also support Microsoft Teams in an Exchange hybrid environment.

Which connection type fits?

Connection type	Who it is for	Guide
Own account	Most users. You sign in with your Exchange email and password.	Below
Account with calendar permission (recommended for organizations)	Companies with compliance requirements. Employees never enter a personal password, and meetergo only sees the calendar, not emails.	Connecting Exchange with Calendar Permission
Service account with impersonation	Organizations that already run a service account with the ApplicationImpersonation role.	Using an Exchange Service Account for Your Connection

Your IT sets up the two organization options. In the connection form they are under Connect through your IT, without your personal password.

Connecting meetergo with Microsoft Exchange

In meetergo, open Integrations and choose Exchange.
Click Add Connection.
Enter your Exchange email address and password. Exchange server, domain and username are optional: meetergo finds your server automatically through Autodiscover.
Click Connect.

If the Microsoft Exchange server isn't discovered, you can specify the URL in the "Exchange server" field, which allows access to Microsoft Exchange via EWS (e.g., https://mail.company.de/ews/exchange.asmx). Additionally, you can specify a different user for authorization using the Domain and Username fields (domain\username).

Write bookings without checking for conflicts

By default, appointments in your Exchange calendar block your booking page. To have meetergo only write bookings into it:

Open Settings → Calendar and click the gear next to the Exchange calendar.
Expand Calendar Options and turn off Check for conflicts.

New bookings still land in your Exchange calendar. Existing appointments there no longer block any times.

For IT admins

Interface: meetergo uses Exchange Web Services (EWS). The EWS endpoint, for example https://mail.yourcompany.com/ews/exchange.asmx, must be reachable from the internet.
Authentication: NTLM. Connections through a fixed IP address use Basic Authentication.
Fixed IP address: If your EWS endpoint should only accept known addresses, we provide a fixed IP address on request that you can add to your firewall. Contact our support.
Without personal passwords: account with calendar permission (Editor rights on the calendar only) or service account with impersonation.

Privacy & Security

We understand the sensitive nature of your access credentials, which enable access to your Microsoft Exchange calendar. Protecting them is our top priority:

Your Microsoft Exchange login credentials are transmitted to our servers over an encrypted SSL connection.
We encrypt these credentials and store them in an isolated database accessible only to authorized system processes.
Your decrypted access credentials are temporarily loaded into memory only when necessary to perform availability queries and utilize our scheduling functions. They are never written to disk.
We minimize the use of your data to an absolute minimum, requesting access only to the calendar necessary for availability checks and appointment scheduling.
We adhere to best practices in key management, access controls, audit trails, and data encryption to safeguard your access credentials.

Our platform undergoes regular security audits to verify the effectiveness of our security measures. Protecting your data is of utmost importance to us.

Why Can't I Connect to My Microsoft Exchange Calendar?

Here are some common reasons why you may not be able to access your Microsoft Exchange calendar:

Incorrect Login Credentials: Verify that you are using the correct email address and password for your work account.
Directly Enter Connection Address: If you only enter your email and password in our form, we attempt to establish a connection using Autodiscover. If this fails, specifying your Microsoft Exchange server's EWS endpoint directly may help. You can also provide your domain\username.
Server Issues: Your company's IT team manages the calendar systems for your work account. Sometimes connection issues occur when these servers are temporarily down or undergoing maintenance. Try again later or contact IT support if the issue persists.
Security Settings: Settings such as calendar permissions, synchronization settings, or security policies could block access to calendar systems. Your IT team can adjust these settings if necessary.
Firewall Blocking Access: If you are connecting outside the office network, a firewall may block connections to calendar systems. Your IT team can investigate this if needed.

If you continue to experience connection issues after trying the above steps, contact your IT support team. Inform them that you are unable to access your Microsoft Exchange calendar from another app. They can then conduct further investigations based on your company's system configuration.
