# Support Microsoft 365 User Email Aliases
This article describes how to configure your SharePoint Online [security identities](https://docs.coveo.com/en/240/) so that your SharePoint Online repository's content permissions are respected when a user logs in to a Coveo-powered [search interface](https://docs.coveo.com/en/2741/) using a Microsoft 365 [email alias](https://docs.microsoft.com/en-us/microsoft-365/admin/email/add-another-email-alias-for-a-user?view=o365-worldwide).

Users may have email aliases assigned to their primary email address in your Microsoft 365 business account, such as to support different corporate domains.
If your SharePoint Online [source](https://docs.coveo.com/en/246/) is configured to [replicate your repository's permission system](https://docs.coveo.com/en/1739#content-security-tab), the [Coveo Platform](https://docs.coveo.com/en/186/) enforces your repository's content permissions based only on a user's primary email address by default.

However, you can configure your SharePoint Online security identity to map user email aliases to their corresponding primary email addresses.
This ensures that your repository's content permissions, which are associated to a user's primary email address in Microsoft 365, also apply when a user logs in to a Coveo-powered search interface using an email alias.

. On the [**Security Identities**](https://platform.cloud.coveo.com/admin/#/orgid/content/permissions/providers/) ([platform-ca](https://platform-ca.cloud.coveo.com/admin/#/orgid/content/permissions/providers/) | [platform-eu](https://platform-eu.cloud.coveo.com/admin/#/orgid/content/permissions/providers/) | [platform-au](https://platform-au.cloud.coveo.com/admin/#/orgid/content/permissions/providers/)) page, click the **Claims to Email** security identity for SharePoint Online, and then click **More** > **Edit JSON** in the Action bar.

. Add the following parameter in the JSON configuration `parameters` section:

```json
"MapAliases": {
    "sensitive": false,
    "value": true
}
```

. Click **Save**.

. [Refresh the **Claims to Email** provider](https://docs.coveo.com/en/1905#refresh-a-security-identity-provider) for the mapping to take effect.
