# Configuring a Service account 

When using on-premise Exchange with Enterprise Connect, you'll need to configure a service account to manage events in the calendars of your users.

Microsoft provide documentation for setting up, and, configuring service accounts, as well as the `ApplicationImpersonation` role. This guide aims to support to that, and will provide you with a good idea of how to create a service account to use with Enterprise Connect.

### Step 1
Create a service account by going to [Office 365 admin center](https://admin.microsoft.com) > USERS > Active Users.

### Step 2
Click on the "+" icon and create a new user account.

### Step 3
Fill in the required information for the Service account:

- Enter the first name, last name, display name, user name, and your email domain.

- Select Type password and enter the password for the service account. Deselect the "Make this person change their password the next time they sign in" check box.

- Enter the email address of the recipient to whom the password must be sent. Select Create.

- Assign an **Office 365 E3** license or higher and finish the account creation wizard by checking the details and pressing Next.

> In order for Rooms and Resources on your Office365/Exchange domain to function with Cronofy, the Service Account **must** have a mailbox and license assigned.

> **INFO:** Multifactor authentication (MFA) is not supported. If MFA is turned on, you need to turn it off for the service account but you can still enable it for other users.

### Next steps
Let's set up the [Application Impersonation](/calendar-admins/enterprise-connect-office365-exchange/configuring-application-impersonation/index.md) role on the new service account, which'll allow your Service account, to manage events in your users calendars.
