email protocol used by webmail (Gmail, Outlook, etc.) and mail apps (Microsoft Outlook, Thunderbird, Apple Mail, etc.). Email clients such as Outlook use POP3 accounts to access your mail server and download all mail locally on the system. In the past, POP3 accounts were mainstream, as they offered features that included network conservation, maximum data privacy, simplified backup, etc. Below, we discuss why they were a popular choice for accessing the mail server.<\/p>\n\n\n\n<h2 class=\"wp-block-heading main_heading\"><span class=\"ez-toc-section\" id=\"How_to_Set_Up_POP3_Account_in_Microsoft_365\"><\/span>How to Set Up POP3 Account in Microsoft 365?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">As we discussed, POP3 accounts were a great choice in the past because of their privacy focus and network conservation.

There were several limitations, such as no cross-sync, less availability of sharing messages, a one-sided download option, etc. Therefore, users prefer to move emails from POP3 account to Microsoft 365 while preserving the folder structure. For this, users can either follow a manual method or use a dedicated tool, but the manual method becomes inefficient for bulk migration. To address this, the <strong>IMAP Migration Tool<\/strong> is the recommended choice. It has a straightforward GUI and versatile features, including duplicate handling, date filters, skipping attachments, etc.<\/p>\n\n\n\n<h3 class=\"wp-block-heading faq-main_heading\"><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions\"><\/span>Frequently Asked Questions<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1789983972736\"><strong class=\"schema-faq-question\"><strong>Q.1 What is the POP3 server for Office 365?<\/strong><\/strong> <p class=\"schema-faq-answer\"><strong>Ans.<\/strong> The POP3 server address for Microsoft 365 is outlook.office365.com.
