This is precisely what occurs when you import PST to IMAP: your email data relocates from an individual machine to a server accessible by any connected device.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This guide outlines two methods for accomplishing this task: a manual procedure using Outlook, and an automated approach using <\/span><a href=\"https:\/\/www.cigatisolutions.com\/pst-converter\/\" target=\"_blank\" rel=\"noopener\"><b>Cigati PST Converter Tool<\/b><\/a><span style=\"font-weight: 400;\">.

Rather than storing messages within a single PST file on one device, &amp; IMAP retains all mailbox data on the server itself.

For unusually large PST files, dividing the migration into smaller batches typically produces more consistent results than a single continuous transfer. Following migration, verification should extend beyond message count alone &#8211; folder contents and attachments should be individually confirmed. The original PST file should be retained until the destination mailbox has been fully verified, as premature deletion eliminates the ability to recover from an incomplete transfer.<\/p>\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span>Conclusion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>This guide has covered the essential aspects of migrating PST data to an IMAP mailbox, from the reasons behind the move to the two available methods &#8211; manual and tool-based. Choosing between them depends largely on the volume of data involved &#038; the resources available: the manual method works for a single small file, while a Cigati tool is better suited to larger or multiple PST files. <\/p>\n<div class=\"faq-n my-4\">\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions\"><\/span>Frequently Asked Questions<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<div class=\"schema-faq wp-block-yoast-faq-block\">\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1789986277962\"><strong class=\"schema-faq-question\"><strong>Q1. Can a PST file be imported directly into an IMAP server without Outlook?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans.<\/strong> Not through the manual method &#8211; Outlook is required to interpret the PST format and transfer its contents. A Cigati PST Converter Tool bypasses this requirement and does not depend on an Outlook installation.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1789986296736\"><strong class=\"schema-faq-question\"><strong>Q2. Is the original PST file deleted or modified during the import process?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans.<\/strong> No. The import process duplicates data to the destination mailbox; the source PST file remains unaltered unless manually deleted afterward.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1789986308935\"><strong class=\"schema-faq-question\"><strong>Q3.

Is migrating a large PST file (10 GB or more) associated with increased risk?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans.<\/strong> Larger files carry a higher probability of timeout, particularly during manual migration.
