Hi @Rachel Evan,

It seems there's some confusion between Azure Communication Services (ACS) and Microsoft 365 (Outlook/Exchange Online) accounts.

Azure Communication Services (ACS) allows you to programmatically create users and enable communication capabilities like chat, voice, video, and SMS within your application. However, ACS user identities are not the same as Microsoft 365 (Outlook/Exchange) user accounts, and they cannot be used to sign in to Outlook or Office apps directly.

So, if you've created a user ID in ACS, that identity can be used in your custom-built apps for ACS communication features. And cannot be added to Outlook or used to log in like a regular email account. This is expected behavior, ACS users are application-specific identities, not standard Microsoft Entra (Azure AD) or Microsoft 365 accounts.

If your goal is to send or receive emails or use Outlook with a mailbox, you'll need to:

1. Create a user in Microsoft Entra ID (Azure Active Directory).
2. Assign that user a Microsoft 365 license that includes Exchange Online (e.g., Microsoft 365 E3 or Business Standard).
3. Once provisioned, you'll receive a mailbox, and you can then add that account to Outlook.

Kindly refer to the below documentation for better understanding:

What is Azure Communication Services?
Create and manage Microsoft 365 users
Assign licenses to users in Microsoft 365
Add an Outlook.com or Microsoft 365 account
