migrations from Exchange, or handling projects, all of them contain historical archives in PSTs. Whereas an Online Archive is a mailbox within a user\u2019s M365 account handling older or infrequently accessed emails for mailbox optimization. It offers several benefits that cannot be utilized with local PST files, such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Cloud storage and automatic backups&nbsp;<\/li>\n\n\n\n<li>Central administration and legal support&nbsp;<\/li>\n\n\n\n<li>Secure access from different devices&nbsp;<\/li>\n\n\n\n<li>Better regulatory governance&nbsp;<\/li>\n\n\n\n<li>Improved performance with free primary space&nbsp;<\/li>\n\n\n\n<li>Centralized management with reduced local dependency<\/li>\n\n\n\n<li>Consolidated data within one space meeting standards&nbsp;<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Prerequisites for PST to Online Archive Migration&nbsp;<\/strong><br><br>Before you proceed with the migration using free or paid software, ensure the following:<br>Assign appropriate licences for Online Archive users&nbsp;Provide Exchange Admin and Microsoft Purview permissions&nbsp;Repair any corrupted PST files if they exist&nbsp;Remove the duplicate entries and verify the data integrity&nbsp;Organize PSTs and ensure you have enough storage space&nbsp;<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Cost-Free_Import_PST_to_Online_Archive_Office_365\"><\/span>Cost-Free Import PST to Online Archive Office 365<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There are two manual methods for importing PST files to the Online mailbox within Office 365. You may need admin credentials for them and an active MS Outlook profile. To know more, go through the step-by-step guide as mentioned below.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Method_1_Transfer_PST_to_Online_Archive_via_Microsoft_Import\"><\/span>Method 1: Transfer PST to Online Archive via Microsoft Import<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Using Microsoft Purview, you get a built-in import feature to make the import. It is suitable if you are an ID admin moving emails for multiple users. The steps to follow here are:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Sign in <\/strong>to the<strong> Microsoft Purview Portal<\/strong> and go to <strong>Data Lifecycle Management<\/strong>.&nbsp;<\/li>\n\n\n\n<li>Click <strong>Import<\/strong> and create a <strong>new PST Import Job<\/strong>.&nbsp;<\/li>\n\n\n\n<li>Download the <strong>Azure AzCopy utility <\/strong>and copy the <strong>SAS URL.&nbsp;<\/strong><\/li>\n\n\n\n<li>Next, upload <strong>PST files<\/strong> with it and ship the <strong>encrypted drives.&nbsp;<\/strong><\/li>\n\n\n\n<li>Further, prepare a <strong>CSV mapping file<\/strong> and link <strong>PSTs<\/strong> with <strong>target mailboxes.<\/strong>&nbsp;<\/li>\n\n\n\n<li>Validate the<strong> mapping<\/strong> and, later, start your <strong>PST Import Job.&nbsp;<\/strong><\/li>\n\n\n\n<li>Monitor the<strong> status<\/strong> in the <strong>progress dashboard <\/strong>until it completes.&nbsp;<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Note:<\/strong> Limit the size of the individual PST files to 20 GB before the import.
