When you configure federation trust, it allows sharing with other federated Exchange environments for sharing calendar free\/busy information, among the recipients.&nbsp;You can configure federated sharing between two federated Exchange organizations or with a Microsoft 365 (Office 365) organization.<\/p><h2 class=\"wp-block-heading\" id=\"why-you-need-to-configure-federation-trust?\">Why you need to configure Federation Trust?<\/h2><p>You need to configure federation trust when you want to share free\/busy information between organizations. For more clarity, let&rsquo;s take an example. A company has acquired another company. One company (parent) was using Exchange Server and the other Office 365. The parent company would like to keep the business going before full migration of both companies to Office 365. So, until the migration is complete, they want to share their free\/busy information with each other and give access to calendars. To do so, Exchange Server offers the federation trust feature.<\/p><blockquote class=\"note_alert\">\n<p>For Hybrid configuration check <a href=\"https:\/\/www.linkedin.com\/pulse\/how-address-federation-trust-issues-hybrid-configuration-\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">How to Address Federation Trust Issues in Hybrid Configuration Wizard<\/a> article.<\/p>\n<\/blockquote><h2 class=\"wp-block-heading\" id=\"configure-federation-trust-with-office-365\">Configure Federation Trust with Office 365<\/h2><p>Before you begin, you need to fulfil the following prerequisites:<\/p><ul class=\"wp-block-list\">\n<li>You (the user) must have the Exchange Server privileges as you need to modify the configuration of the Exchange Server locally.<\/li>\n\n\n\n<li>You must have the global administrator privileges of the Office 365 tenant as you need to modify both parties.<\/li>\n\n\n\n<li>You need to have access to the DNS zone of the Exchange Server (local) as a TXT record need to be added.<\/li>\n\n\n\n<li>Ensure that the Auto Discover service on the local Exchange Server is working with no issues.<\/li>\n<\/ul><p>Once you have fulfilled the above, you can proceed with the setup.<\/p><h3 class=\"wp-block-heading\">Steps to Configure Federation Trust on Local Exchange Server<\/h3><ul class=\"wp-block-list\">\n<li>Log in to the <strong><a href=\"https:\/\/www.stellarinfo.com\/blog\/how-to-access-exchange-admin-center\/\" target=\"_blank\" rel=\"noreferrer noopener\">Exchange Admin Center (EAC)<\/a><\/strong> as administrator.<\/li>\n\n\n\n<li>Click on <strong>Organization<\/strong> and then click on <strong>Sharing<\/strong>.<\/li>\n<\/ul><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"499\" height=\"284\" src=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/09\/Configure-Federation-Trust-on-Local-Exchange-Server.png\" alt=\"Configure Federation Trust on Local Exchange Server\" class=\"wp-image-147985 apply-gradient-on-post-images\" srcset=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/09\/Configure-Federation-Trust-on-Local-Exchange-Server.png 499w, https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/09\/Configure-Federation-Trust-on-Local-Exchange-Server-300x171.png 300w, https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/09\/Configure-Federation-Trust-on-Local-Exchange-Server-150x85.png 150w\" sizes=\"auto, (max-width: 499px) 100vw, 499px\" \/><\/figure><ul class=\"wp-block-list\">\n<li>Click on <strong>Enable<\/strong>.<\/li>\n\n\n\n<li>Under the <strong>Organization<\/strong> <strong>Sharing<\/strong>, click on the <strong>Add<\/strong> button.<\/li>\n<\/ul><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"621\" height=\"144\" src=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/09\/Add-Federation-Trust-on-Local-Exchange-Server.png\" alt=\"Add Federation Trust on Local Exchange Server\" class=\"wp-image-147986 apply-gradient-on-post-images\" srcset=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/09\/Add-Federation-Trust-on-Local-Exchange-Server.png 621w, https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/09\/Add-Federation-Trust-on-Local-Exchange-Server-300x70.png 300w, https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/09\/Add-Federation-Trust-on-Local-Exchange-Server-150x35.png 150w\" sizes=\"auto, (max-width: 621px) 100vw, 621px\" \/><\/figure><ul class=\"wp-block-list\">\n<li>Enter the name of the relationship and the domain name to share with.

You would need to consult with the local network team to ensure that all is unblocked and traffic is allowed from the local Exchange Server to Office 365.<\/p><p>If all is configured well and still the free\/busy information is not visible, you can try to restart the <strong>World Wide Web Publishing Service<\/strong> (IIS) from the <strong>Services<\/strong> control panel on the local Exchange Server.

You need to consider the domains, along with the cleanup of mailboxes before the move. Migration of data can be simple or complex, depending on the method you use. You need to also consider the cost of migration and the resources needed for the operation.<\/p><p>Using a <a href=\"https:\/\/www.stellarinfo.com\/exchange-migration.php\">Exchange Migration<\/a> tool like Stellar Migrator for Exchange can significantly simplify the process. The application enables direct migration of user mailboxes, archive mailboxes, and public folders from Exchange Server to Office 365 or another live Exchange Server, with minimal disruption. With features like parallel processing, priority mailbox migration, automatic and manual mailbox mapping, the software ensures an efficient and streamlined transition. It helps reduce downtime, lowers the overall cost of migration, and minimizes the demand on IT resources, making it an ideal solution for both small and large-scale Exchange migrations.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Exchange Server provides a feature, called federation trust that allows to establish&hellip; <a class=\"more-link\" href=\"https:\/\/www.stellarinfo.com\/blog\/configure-federation-trust-with-office-365\/\">Continue reading <span class=\"screen-reader-text\">How to Configure Federation Trust with Office 365?<\/span><\/a><\/p>\n","protected":false},"author":17,"featured_media":148070,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[6204,2960],"tags":[5428],"class_list":["post-147983","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-exchange-to-office-365","category-migrate-to-office-365","tag-configure-federation-trust","entry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.9 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>How to Configure Federation Trust with Office 365? | Stellar<\/title>\n<meta name=\"description\" content=\"In this blog, we have discussed how to configure a federation trust between your Local Exchange Server and Office 365.
