The group exploited the ProxyLogon vulnerabilities on the on-premise Exchange server to access and compromise the Exchange servers.<\/p><p>HAFNIUM is by far the most devastating and invasive attack on Exchange on-premises versions that compromised more than 30,000 organizations worldwide. Such Increasing threats and attacks on Microsoft Exchange on-premises server are pushing organizations and businesses across the globe to move their emails from Exchange on-premises to a more secure cloud-based Exchange Online or Office 365, which is unaffected by such attacks.<\/p><p>In this post, we discussed the best Office 365 migration tools to migrate all mailboxes from Exchange 2019, 2016, 2013, 2010, 2007, 2003, 2000, or 5.5 version to Microsoft Office 365 with 100% integrity and precision. &nbsp;<\/p><h2 class=\"wp-block-heading\" id=\"best-office-365-migration-tool\"><strong>Best Office 365 Migration Tool<\/strong><\/h2><p>Although you can use the manual methods to migrate mailboxes and data from Exchange on-premises to Office 365, these methods are often complex and have many limitations. For instance, Cutover Migration limits 2000 mailboxes and takes several days to migrate the mailboxes, which causes extended downtime and impacts users. Also, it doesn&rsquo;t work when the mailbox database is dismounted or offline.<\/p><p>An Office 365 migration tool overcomes these limitations and helps you quickly migrate mailboxes from on-premises Exchange to Office 365 without any risk of data loss or corruption. They facilitate 1:1 migration while maintaining the original folder structure and content. You can also add various filters to migrate desired mailboxes or mail items to Office 365 and save time.<\/p><h3 class=\"wp-block-heading\" id=\"h-1-stellar-converter-for-edb\">1.
