Supported Providers

Microsoft Shared Calendars

Microsoft Shared Calendars are not supported through the Nylas Calendar API.

Microsoft National Clouds

Accounts provisioned on national cloud environments like the United States Government, China, or Germany are not supported at this time. These environments use different Azure AD endpoint URLs for authentication.

We currently only support accounts authenticated using the Azure AD (global services) endpoint URLs:

Individual Mailboxes

Nylas supports only individual mailboxes for Microsoft accounts. Alias accounts, shared mailboxes, distribution groups, and Microsoft 365 group lists aren't supported.

Distribution lists for Microsoft accounts work in Nylas. Connected user accounts can send and receive emails from distribution lists. To send emails through distribution lists, users can set the from and reply_to fields to the distribution list email.
