But how did it affect business at such a large scale? Email accessibility, send\/receive and management that work as a core part of any business architecture, is disrupted due to this outage. Not just Exchange Online, but SharePoint, Teams, and OneDrive are also affected during this disruption. As a result, it calls for a need to regularly check the health status, take precautions, and keep backups of your confidential mailboxes in advance. But before that, let\u2019s dive deep into the core of this issue and learn the use of Tenant-to-Tenant Migration<\/span><span style=\"font-weight: 400;\">\u00a0to take better action. <\/span><\/strong><\/strong><\/em><\/div>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_83 counter-hierarchy ez-toc-counter ez-toc-light-blue ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 eztoc-toggle-hide-by-default' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.arysontechnologies.com\/blog\/microsoft-365-native-migration-doesnt-work\/#What_Happened_During_the_Microsoft_Outlook_Outage_in_November_2026\" >What Happened During the Microsoft Outlook Outage in November 2026?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.arysontechnologies.com\/blog\/microsoft-365-native-migration-doesnt-work\/#Microsoft_Services_Affected_By_M365_Global_Outage\" >Microsoft Services Affected By M365 Global Outage<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/www.arysontechnologies.com\/blog\/microsoft-365-native-migration-doesnt-work\/#Why_Is_Microsoft_Outlook_Not_Working_Understanding_the_Cause\" >Why Is Microsoft Outlook Not Working?

Microsoft also confirmed that these issues with Exchange Online are occurring because its servers were experiencing high workloads. Apart from Exchange Online, a widespread Microsoft outage affects Outlook and Teams services eventually.<\/p>\n<p>Moreover, Downdetector recorded nearly 130,000 US Outlook problem reports at the reported peak, with reports from 74 countries and territories within about an hour. These were user-submitted reports, not confirmed affected accounts. Reports described disruption lasting more than nine hours.<\/p>\n<p>Microsoft tracked the wider issue as MO1550821 and the Exchange Online incident as EX1550543, covering connection failures across multiple methods.<\/p>\n<p>Microsoft&#8217;s incident notes listed Outlook on the web, MAPI, Exchange ActiveSync, and REST API among affected connection methods. The same mailbox issue could therefore appear in desktop clients, browsers, and connected applications, not just Outlook or other email clients.<\/p>\n<h2 class=\"main_heading\"><span class=\"ez-toc-section\" id=\"Microsoft_Services_Affected_By_M365_Global_Outage\"><\/span>Microsoft Services Affected By M365 Global Outage<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Exchange Online was the primary affected service, with connected Microsoft 365 experiences also disrupted.

Is there a problem with Microsoft Outlook now?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans:<\/strong> Yes. Microsoft Outlook recently experienced widespread access and connection issues during the November 2026 outage. To check whether the problem is still affecting your account, visit Microsoft&#8217;s Service Health page for the latest updates. You can use the Aryson tenant-to-tenant migration software to keep your essential data completely safe.\u00a0<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1794641088301\"><strong class=\"schema-faq-question\"><strong>Q2. Why is there a Microsoft Outlook outage?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans:<\/strong> Microsoft reported that the outage was linked to the heavy workload problems, including elevated server load and servers becoming unavailable after failing automated health checks. The company said it had found no indication of malicious or cyber activity. A definitive root cause had not yet been confirmed.\u00a0<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1794641089086\"><strong class=\"schema-faq-question\"><strong>Q3. How did the Outlook outage affect workflows?\u00a0<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans:<\/strong> The November 2026 outage affected Outlook and Exchange Online, along with some Microsoft 365 services, including Teams, Copilot, SharePoint, and OneDrive. The impact was completely different across services and regions. Microsoft continued recovery efforts on November 13, while service availability remained inconsistent.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1794641090285\"><strong class=\"schema-faq-question\"><strong>Q4. Can Aryson migrate Outlook mailboxes between Microsoft 365 tenants?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans:<\/strong> Yes. Aryson migrates Exchange Online mailboxes, including emails, contacts, calendars, attachments, tasks, permissions, rules, and automatic replies between Microsoft 365 tenants.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1794641090940\"><strong class=\"schema-faq-question\"><strong>Q5. Does Aryson preserve mailbox folder structure during migration?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans:<\/strong> Yes. The software makes sure to keep the supported mailbox folder hierarchy, metadata, and attachments intact. That too, while transferring mailbox data to the destination Microsoft 365 tenant.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1794641091588\"><strong class=\"schema-faq-question\"><strong>Q6. Can I migrate selected Microsoft 365 mailboxes instead of the entire tenant?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans:<\/strong> Yes. With the help of the Aryson Tenant-to-Tenant migration tool, administrators can select specific mailboxes, users, and folders for migration. The software also supports CSV-based mapping for bulk user migration.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1794641092444\"><strong class=\"schema-faq-question\"><strong>Q7. Does Aryson support duplicate email detection during migration?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans:<\/strong> Yes. Its Email Deduplication module identifies duplicate emails by comparing details such as subject, sender, recipients, and message content.
