accessibility<\/li>\n<\/ul>\n<p>Furthermore, as compared to email exports, migrating a PST file to Exchange Online requires the consideration of:<\/p>\n<ul>\n<li>Mailbox size

Also, it enabled audit-compliant logs to support their internal documentation.<\/p>\n<br \/>\n<p>The <strong>CTO of Legal Operations Firm<\/strong> stated,<\/p>\n<p><em>&#8220;We went from near chaos to full compliance in less time, without disrupting workflow and with precision.&#8221;<\/em><\/p>\n<\/div>\n<p><strong>Quick Guide to Migrate PST to Exchange Online<\/strong><\/p>\n<ol>\n<li>Run the <strong>PST to Exchange Online Import Tool<\/strong> and tap <strong>Restore.<\/strong><\/li>\n<li>After that, continue to <strong>single <\/strong>or<strong> batch<\/strong> import <strong>PST <\/strong>files into the tool.<\/li>\n<li>Click <strong>Next<\/strong>, and further, you&rsquo;ll find <strong>Office 365 Exchange<\/strong> as the output type.<\/li>\n<li><strong>Sign in<\/strong> with your <strong>Exchange Online<\/strong> account by modern authentication.<\/li>\n<li>Later, pick the filters from the unique interface and click on <strong>Next<\/strong>.<\/li>\n<li>At last, choose your respective <strong>Exchange mailboxes<\/strong> and click <strong>Restore<\/strong>.<\/li>\n<\/ol>\n<p>Isn&rsquo;t this a lot simpler, straightforward, quick, secure, and efficient?

It is a strategic step for centralizing, securing, and complying with email management.

Whereas, the <strong>PST to Office 365 Migrator<\/strong> doesn\u2019t have any specific file size or mailbox size limit when you import PST in Exchange Online.
