Microsoft 365 offers Exchange Online along with programs like Outlook, Teams, SharePoint, Word, and Excel. Since both of these systems handle business email, companies might decide to migrate AWS WorkMail to Office 365 when they want to move their email system to Microsoft&#8217;s cloud.<\/p>\n<p>Amazon WorkMail works with IMAP, which means that email data can be moved to Microsoft 365 via the IMAP process from Microsoft. However, the normal IMAP migration is mainly for email and mail folders. It does not bring over contacts, calendars or tasks. Companies that need ways to move their data might look into professional software based on what they need to move.<\/p>\n<\/div>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_85 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 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.cigatisolutions.com\/blog\/migrate-aws-workmail-to-office-365\/#Is_it_Possible_to_Migrate_from_Amazon_WorkMail_to_Office_365\" >Is it Possible to Migrate from Amazon WorkMail to Office 365?<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.cigatisolutions.com\/blog\/migrate-aws-workmail-to-office-365\/#What_Data_Can_Be_Moved\" >What Data Can Be Moved?<\/a><\/li><\/ul><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/www.cigatisolutions.com\/blog\/migrate-aws-workmail-to-office-365\/#Manual_Way_to_Migrate_AWS_WorkMail_to_Office_365_IMAP\" >Manual Way to Migrate AWS WorkMail to Office 365 (IMAP)<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/www.cigatisolutions.com\/blog\/migrate-aws-workmail-to-office-365\/#Limitations_of_the_IMAP_Process\" >Limitations of the IMAP Process<\/a><\/li><\/ul><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/www.cigatisolutions.com\/blog\/migrate-aws-workmail-to-office-365\/#Professional_Way_to_Migrate_AWS_WorkMail_to_Office_365\" >Professional Way to Migrate AWS WorkMail to Office 365<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/www.cigatisolutions.com\/blog\/migrate-aws-workmail-to-office-365\/#Pre-Migration_Checklist\" >Pre-Migration Checklist<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-7\" href=\"https:\/\/www.cigatisolutions.com\/blog\/migrate-aws-workmail-to-office-365\/#Post-Migration_Check_Migrate_Emails_from_AWS_WorkMail_to_Microsoft_365\" >Post-Migration Check: Migrate Emails from AWS WorkMail to Microsoft 365<\/a><\/li><\/ul><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-8\" href=\"https:\/\/www.cigatisolutions.com\/blog\/migrate-aws-workmail-to-office-365\/#Conclusion\" >Conclusion<\/a><ul class='ez-toc-list-level-4' ><li class='ez-toc-heading-level-4'><ul class='ez-toc-list-level-4' ><li class='ez-toc-heading-level-4'><a class=\"ez-toc-link ez-toc-heading-9\" href=\"https:\/\/www.cigatisolutions.com\/blog\/migrate-aws-workmail-to-office-365\/#Frequently_Asked_Questions\" >Frequently Asked Questions<\/a><\/li><\/ul><\/li><\/ul><\/li><\/ul><\/nav><\/div>\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Is_it_Possible_to_Migrate_from_Amazon_WorkMail_to_Office_365\"><\/span>Is it Possible to Migrate from Amazon WorkMail to Office 365?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Yes, people can easily transfer their Amazon WorkMail to Microsoft 365. Amazon WorkMail has IMAP support, so administrators can move emails and mail folders to Microsoft 365 using the IMAP method from Microsoft. However, this method does not move contacts, calendars, or tasks. For companies that need options like filters or detailed reports, a third-party migration tool can be helpful. The right way to do it depends on the type &amp; amount of data from Amazon WorkMail that needs to be moved.<\/p>\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Data_Can_Be_Moved\"><\/span>What Data Can Be Moved?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Emails<\/b><span style=\"font-weight: 400;\">: Email messages migrate Amazon WorkMail to Office 365.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Mail Folders<\/b><span style=\"font-weight: 400;\">: Transfer the Inbox, Sent Items, Drafts, &amp; other custom folders.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Attachments<\/b><span style=\"font-weight: 400;\">: Attachments that go with the emails can be moved along with the messages.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Contacts:<\/b><span style=\"font-weight: 400;\"> These are not moved through the IMAP process that Microsoft offers.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Calendars: <\/b><span style=\"font-weight: 400;\">These are not moved through the IMAP process that Microsoft offers.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Tasks:<\/b><span style=\"font-weight: 400;\"> These are not moved through the IMAP process that Microsoft offers.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Folder Structure<\/b><span style=\"font-weight: 400;\">: The folders that can be moved can be set up again in the Microsoft 365 mailbox.<\/span><\/li>\n<\/ul>\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Manual_Way_to_Migrate_AWS_WorkMail_to_Office_365_IMAP\"><\/span>Manual Way to Migrate AWS WorkMail to Office 365 (IMAP)<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">You can use the IMAP process that Microsoft provides and the IMAP process will move the email data, from Amazon WorkMail to Microsoft 365.<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Make sure the target mailboxes in Microsoft 365 are created &amp; verified before you start the move.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Get the IMAP endpoint for Amazon WorkMail &amp; make sure that IMAP access is available.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Verify the Microsoft 365 mailboxes to make sure that the messages &amp; folders made it correctly.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Configure the IMAP migration setup in the Microsoft 365 Exchange admin center.
