Accumulation is faster than most users realize.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why does the 552 5.2.2 error occur?<\/h2>\n\n\n\n<p>Quota exhaustion happens gradually, then suddenly blocks all incoming mail.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Inbox neglect<\/h3>\n\n\n\n<p>Recipients who rarely delete messages accumulate years of email. Large inboxes eventually hit limits.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Large attachments<\/h3>\n\n\n\n<p>Frequent receipt of files (photos, documents, videos) fills quota faster than text-only correspondence.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Trash not emptied<\/h3>\n\n\n\n<p>Deleted messages move to Trash but still count toward quota until permanently deleted (usually 30 days auto-empty, but not always).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Retention policies<\/h3>\n\n\n\n<p>Organizations sometimes apply retention holds that prevent deletion, filling mailboxes with messages users can&#8217;t remove.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Forwarding loops<\/h3>\n\n\n\n<p>Misconfigured forwarding to another full mailbox can cause the original mailbox to receive bounces, further consuming quota.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How do you fix 552 5.2.2?<\/h2>\n\n\n\n<p>Your fix depends on whether you&#8217;re the sender (limited options) or recipient (full control).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">For recipients<\/h3>\n\n\n\n<p>If you&#8217;re receiving this bounce for your own mailbox (someone trying to reach

class=\"wp-block-heading\">Reduce attachment size<\/h4>\n\n\n\n<p>Make your message smaller:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Compress files before attaching<\/li>\n\n\n\n<li>Use cloud

marketing or bulk mail:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Log the bounce<\/li>\n\n\n\n<li>Skip retries for this recipient<\/li>\n\n\n\n<li>Try next campaign again (they may have cleared space)<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How do you handle persistent quota bounces?<\/h2>\n\n\n\n<p>Repeated 552 5.2.2 errors from the same recipient indicate chronic neglect \u2014 treat differently from one-time occurrences.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">For important contacts<\/h3>\n\n\n\n<p>Escalate outreach:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Call
