This is especially relevant for organizations facing <strong>limitations with traditional email platforms like Exchange Online<\/strong>. This article <strong>explains ACS <\/strong>and its<strong> licensing<\/strong>, <strong>compares <\/strong>it to<strong> Exchange Online<\/strong>, and answers frequently asked questions (<strong>FAQ<\/strong>).<\/p>\n<p>&nbsp;<\/p>\n<h2 style=\"text-align: justify;\"><strong>What is Azure Communication Services (ACS)?<\/strong><\/h2>\n<p style=\"text-align: justify;\"><strong><a href=\"https:\/\/www.schneider.systems\/lu\/microsoft-azure-licensing-full-guide\/\">Microsoft Azure<\/a> Communication Services (ACS) <\/strong>is a cloud-based platform that provides <strong>communication features (like email, SMS text messaging, voice and video calling<\/strong>) which developers and IT teams can embed into their applications or workflows.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-60754\" src=\"https:\/\/www.schneider.systems\/media\/2025\/07\/SCHNEIDER-IT-MANAGEMENT-2025-07-02-Update-Microsoft-Azure-Communication-Services-Overview.png\" alt=\"\" width=\"1235\" height=\"757\" srcset=\"https:\/\/www.schneider.systems\/media\/2025\/07\/SCHNEIDER-IT-MANAGEMENT-2025-07-02-Update-Microsoft-Azure-Communication-Services-Overview.png 1235w, https:\/\/www.schneider.systems\/media\/2025\/07\/SCHNEIDER-IT-MANAGEMENT-2025-07-02-Update-Microsoft-Azure-Communication-Services-Overview-500x306.png 500w, https:\/\/www.schneider.systems\/media\/2025\/07\/SCHNEIDER-IT-MANAGEMENT-2025-07-02-Update-Microsoft-Azure-Communication-Services-Overview-800x490.png 800w, https:\/\/www.schneider.systems\/media\/2025\/07\/SCHNEIDER-IT-MANAGEMENT-2025-07-02-Update-Microsoft-Azure-Communication-Services-Overview-150x92.png 150w, https:\/\/www.schneider.systems\/media\/2025\/07\/SCHNEIDER-IT-MANAGEMENT-2025-07-02-Update-Microsoft-Azure-Communication-Services-Overview-768x471.png 768w\" sizes=\"auto, (max-width: 1235px) 100vw, 1235px\" \/><\/p>\n<p style=\"text-align: justify;\">In the <strong>context of email<\/strong>, Azure Communication Services is an <strong>email-sending service designed for large scale<\/strong>. It allows organizations to <strong>send emails directly through Azure\u2019s cloud infrastructure<\/strong>. This is <strong>not an email inbox or a replacement for your Outlook<\/strong>; instead, it is a service focused on <strong>large volumes of outbound emails<\/strong>.<\/p>\n<p style=\"text-align: justify;\">While <strong>you can use Azure Communication Services for lots of communication options<\/strong>, this <strong>article focuses on emails<\/strong>.<\/p>\n<p>&nbsp;<\/p>\n<h2 style=\"text-align: justify;\"><strong>Key Features of ACS email<\/strong><\/h2>\n<ul style=\"text-align: justify;\">\n<li><strong>No External Recipient Limits: <\/strong>There are no limits on how many emails or recipients you can send to using ACS. For example, Exchange Online caps you at roughly 2,000 external recipients per day, but Azure Communication Services can handle massive volumes (internally Microsoft has tested around\u00a0<strong>2 million emails per hour<\/strong>\u00a0on ACS).<\/li>\n<li><strong>High Scalability and Throughput: <\/strong>ACS can automatically handle sudden surges in email traffic. If you need to send 10,000 emails one hour and 500,000 the next, ACS will accommodate that. You don\u2019t have to provision new servers or worry about downtime.<\/li>\n<li><strong>Flexible Integration (SMTP and APIs): <\/strong>For quick deployment, you can use <strong>SMTP<\/strong> (Simple Mail Transfer Protocol), the standard method for sending emails, which works with most email tools and scripts. This lets you configure ACS as an outbound email server with minimal changes. For more advanced use, ACS offers <strong>REST APIs <\/strong>(Representational State Transfer API)<strong> and SDKs<\/strong> (Software Development Kits) for .NET, Java, Python, and JavaScript\u2014ideal for developers who want to embed email-sending directly into applications, like sending automated receipts or alerts.<\/li>\n<li><strong>Security and Authentication: <\/strong>ACS supports\u00a0<strong>TLS (Transport Layer Security)<\/strong>\u00a0encryption, meaning every email sent is encrypted in transit for privacy. It also uses modern authentication methods: Authenticate to ACS using\u00a0<strong><a href=\"https:\/\/www.schneider.systems\/lu\/microsoft-entra-available\/\">Microsoft Entra<\/a> ID<\/strong>\u00a0(formerly <a href=\"https:\/\/www.schneider.systems\/lu\/microsoft-azure-ad-becomes-microsoft-entra-id\/\">Azure Active Directory<\/a>) or using secure access keys. Additionally, ACS supports authentication protocols like\u00a0<strong>SPF (Sender Policy Framework)<\/strong>\u00a0and\u00a0<strong>DKIM (DomainKeys Identified Mail)<\/strong>\u00a0for your sending domain, helping ensure your emails are trusted and not marked as spam.<\/li>\n<li><strong><a href=\"https:\/\/www.schneider.systems\/lu\/microsoft-intune-advanced-analytics-part-of-intune-suite\/\">Advanced Analytics<\/a> and Monitoring:<\/strong> ACS lets you see how many emails were sent, how many were delivered, and how many failed. You can also track engagement, and logs can be stored in Azure Storage for compliance or fed into monitoring dashboards. With Azure Monitor, you can set up alerts, for example, to notify you if email delivery rates drop or if a sudden surge in volume occurs.<\/li>\n<li><strong>Cost-Efficient Pay-As-You-Go Pricing: <\/strong>With ACS, there are\u00a0<em>no upfront license fees<\/em>\u00a0specifically for email. You <strong>pay\u00a0per use<\/strong>.<\/li>\n<li><strong>Centralized Management: <\/strong>Manage everything directly in the <strong>Azure portal<\/strong>.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2 style=\"text-align: justify;\"><strong>Licensing<\/strong><\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-60758\" src=\"https:\/\/www.schneider.systems\/media\/2025\/07\/SCHNEIDER-IT-MANAGEMENT-2025-07-02-Update-Microsoft-Azure-Communication-Services-Pricing.png\" alt=\"\" width=\"360\" height=\"265\" srcset=\"https:\/\/www.schneider.systems\/media\/2025\/07\/SCHNEIDER-IT-MANAGEMENT-2025-07-02-Update-Microsoft-Azure-Communication-Services-Pricing.png 360w, https:\/\/www.schneider.systems\/media\/2025\/07\/SCHNEIDER-IT-MANAGEMENT-2025-07-02-Update-Microsoft-Azure-Communication-Services-Pricing-150x110.png 150w\" sizes=\"auto, (max-width: 360px) 100vw, 360px\" \/><\/p>\n<p style=\"text-align: justify;\"><strong>ACS uses Pay-as-you-go (PAYG) billing instead of a separate \u201clicense\u201d. <\/strong>It is part of the Azure platform, so you use it as an <strong>Azure service<\/strong>. Here\u2019s what that means in practice:<\/p>\n<ul style=\"text-align: justify;\">\n<li><strong><a href=\"https:\/\/www.schneider.systems\/lu\/microsoft-azure-new-policy-on-unused-subscriptions-blocking-and-deletion\/\">Azure Subscription<\/a>:<\/strong> The ACS service\u2019s usage is tied to your Azure subscription and the associated billing account. If you don\u2019t have an Azure subscription, <a href=\"https:\/\/www.schneider.systems\/contact\/\">ask SCHNEIDER IT MANAGEMENT to benefit from better pricing, technical support and optimization<\/a>.<\/li>\n<li><strong>Pay-As-You-Go Pricing: <\/strong>Azure Communication Services uses a consumption-based billing model. For the email service, you are billed based on the number of emails sent and the amount of data (in megabytes) that you send. <strong>Example Cost for 10,000 Emails<\/strong> (for educational purposes only):\n<ul style=\"text-align: justify;\">\n<li><strong>Email sends<\/strong>: 10,000 \u00d7 $0.00025 =\u00a0<strong>$2.50<\/strong><\/li>\n<li><strong>Data (assuming 0.5 MB per email)<\/strong>: 5,000 MB \u00d7 $0.00012 =\u00a0<strong>$0.60<\/strong><\/li>\n<li><strong>Total estimated cost<\/strong>:\u00a0<strong>$3.10<\/strong><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<ul style=\"text-align: justify;\">\n<li><strong>No User License Needed: <\/strong>Unlike Exchange Online, where typically you need to have a licensed mailbox for a user, ACS <strong>doesn\u2019t require any user mailbox licenses<\/strong>. It is purely an Azure service.<\/li>\n<li><strong>Domain Setup: <\/strong>From a licensing perspective, there\u2019s <strong>no extra cost to set up multiple domains or addresses<\/strong> in ACS. You need to verify that you own any sender domains (like\u00a0com) by adding DNS records, but that is a one-time setup and not a fee.<\/li>\n<li><strong>Monitoring Costs: <\/strong>All basic functionality of ACS (sending emails, viewing logs in Azure, etc.) is covered by the usage costs. If you choose to <strong>store logs or data long-term<\/strong> (like storing delivery logs in Azure Storage or using Application Insights), those Azure services may have their own <strong>minimal costs<\/strong>. Generally, these costs are small. This occurs, e.g., when storing emails logs for a year in Azure.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2><strong>How it works<\/strong><\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-60764\" src=\"https:\/\/www.schneider.systems\/media\/2025\/07\/SCHNEIDER-IT-MANAGEMENT-2025-07-02-Update-Microsoft-Azure-Communication-Services-process.webp\" alt=\"\" width=\"999\" height=\"439\" srcset=\"https:\/\/www.schneider.systems\/media\/2025\/07\/SCHNEIDER-IT-MANAGEMENT-2025-07-02-Update-Microsoft-Azure-Communication-Services-process.webp 999w, https:\/\/www.schneider.systems\/media\/2025\/07\/SCHNEIDER-IT-MANAGEMENT-2025-07-02-Update-Microsoft-Azure-Communication-Services-process-500x220.webp 500w, https:\/\/www.schneider.systems\/media\/2025\/07\/SCHNEIDER-IT-MANAGEMENT-2025-07-02-Update-Microsoft-Azure-Communication-Services-process-800x352.webp 800w, https:\/\/www.schneider.systems\/media\/2025\/07\/SCHNEIDER-IT-MANAGEMENT-2025-07-02-Update-Microsoft-Azure-Communication-Services-process-150x66.webp 150w, https:\/\/www.schneider.systems\/media\/2025\/07\/SCHNEIDER-IT-MANAGEMENT-2025-07-02-Update-Microsoft-Azure-Communication-Services-process-768x337.webp 768w\" sizes=\"auto, (max-width: 999px) 100vw, 999px\" \/><\/p>\n<p style=\"text-align: justify;\">Here&#8217;s a breakdown of the process:<\/p>\n<ol style=\"text-align: justify;\">\n<li><strong>Contoso Application<\/strong>: This is the application that initiates email delivery \u2013 typically a custom app or backend service.<\/li>\n<li><strong>Email API<\/strong>: The application uses the ACS Email API to send emails. This API is part of Azure Communication Services.<\/li>\n<li><strong>Azure Communication Services<\/strong>: ACS processes the incoming API calls and forwards them to the internal email processing service. The messaging and calling icons indicate that ACS also supports other communication channels.<\/li>\n<li><strong>Email Processing Service<\/strong>: This service handles the actual processing of emails \u2013 e.g., formatting, deliverability, queuing, and forwarding.<\/li>\n<li><strong>Exchange Online<\/strong>: ACS uses Exchange Online as a transport mechanism to actually deliver the emails. ACS is still a separate service. It provides APIs for sending emails, SMS, chat, and voice\/video calls. The use of Exchange Online is an implementation detail\u2014you don\u2019t need an Exchange Online license or tenant to use ACS Email.<\/li>\n<li><strong>End User Mailboxes<\/strong>: The emails are finally delivered to the end users&#8217; mailboxes \u2013 e.g., Outlook or Gmail.<\/li>\n<\/ol>\n<p style=\"text-align: justify;\">This architecture is well-suited for\u00a0<strong>high-volume transactional or notification email scenarios<\/strong>, offering scalability, reliability, and integration with Microsoft\u2019s cloud ecosystem.<\/p>\n<p>&nbsp;<\/p>\n<h2 style=\"text-align: justify;\"><strong>Use Cases<\/strong><\/h2>\n<ul style=\"text-align: justify;\">\n<li><strong>Marketing <\/strong><strong>Campaigns: <\/strong>Send promotional emails to thousands or millions of customers without worrying about delivery limits.<\/li>\n<li><strong>Transactional Messaging<\/strong><strong>: <\/strong>Deliver order confirmations, password resets, and alerts reliably and securely.<\/li>\n<li><strong>Customer Support Automation<\/strong><strong>: <\/strong>Integrate ACS into support platforms to send automated responses and updates.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2 style=\"text-align: justify;\"><strong>Comparison: Azure Communication Services vs. Exchange Online<\/strong><\/h2>\n<p style=\"text-align: justify;\"><strong>Azure Communication Services and Exchange Online complement each other rather than compete directly<\/strong>.

Exchange Online will continue to serve its purpose for user mailboxes, person-to-person emails, calendar invites, etc. ACS is used for\u00a0<em>specific high-volume sending scenarios<\/em>. You might route your bulk outbound emails (like marketing blasts, automated notifications, etc.) through ACS, while keeping regular business correspondence on Exchange Online.<\/p>\n<h3 style=\"text-align: justify;\"><strong>We don\u2019t usually send huge volumes of emails. Is ACS still useful for us?<\/strong><\/h3>\n<p style=\"text-align: justify;\">If your organization rarely, if ever, needs to send large batches of email, you might not need Azure Communication Services for email right now.\u00a0<strong>ACS solves a specific problem \u2013 high-volume email sending<\/strong>. If you\u2019re not encountering that problem, you might stick with your existing email solution (like Exchange Online or another service) which is working fine for your needs. This solution is good to keep in mind for a future change of your requirements. Besides email, ACS is useful for other scenarios like chat, calling, audio streaming and more.<\/p>\n<h3 style=\"text-align: justify;\"><strong>Can I send emails with attachments and rich content through ACS?<\/strong><\/h3>\n<p style=\"text-align: justify;\"><strong>Yes.<\/strong>\u00a0Azure Communication Services supports attachments and HTML content in the emails you send. Many organizations use ACS to send monthly PDF reports to clients, event invitations with branding, or product update emails with images. There are some size limits: ACS supports emails up to 25 MB in size, similar to Exchange Online\u2019s limits. Remember that attachments contribute to the data volume, which in turn contributes to the cost (e.g., sending 10 MB attachment to 1,000 people is 10,000 MB of data).<\/p>\n<h3 style=\"text-align: justify;\"><strong>Will I save money with ACS compared to other solutions?<\/strong><\/h3>\n<p style=\"text-align: justify;\"><strong>It depends on your usage. <\/strong>Compared to maintaining your own email servers for bulk sending, ACS is likely much more cost-efficient when you account for hardware, maintenance, and IT labor. Against other cloud email services, ACS is competitively priced. One clear advantage is you\u00a0<strong>don\u2019t pay for ACS when you\u2019re not using it<\/strong>. For example, if you send emails in bursts (say, one big burst a quarter), you are not paying a high monthly fee in between.
