However, there comes a time when the dreaded notification pops up: &#8220;Mailbox Size Limit Exceeded.&#8221; This typical message signals that your email account has reached its storage capacity, restricting your ability to send, receive, or access emails. But fear not! Here\u2019s a guide on how to manage and overcome this common issue.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When your mailbox size exceeds its limit, it restricts incoming emails and might prevent you from sending new ones. In other words, it occurs when your email server allocates a specific storage size to your account, and you accumulate emails, attachments, and other data. It reaches its maximum capacity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Also Read:<\/strong> <a href=\"https:\/\/www.cigatisolutions.com\/blog\/increase-outlook-pst-file-size-limit\/\">Increase Outlook PST File Size Limit<\/a><\/p>\n\n\n\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_85 counter-hierarchy ez-toc-counter ez-toc-light-blue ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.cigatisolutions.com\/blog\/outlook-mailbox-size-limit-exceeded-error\/#How_does_this_Outlook_Mailbox_Quota_Exceeded_Error_Occur\" >How does this Outlook Mailbox Quota Exceeded Error Occur?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.cigatisolutions.com\/blog\/outlook-mailbox-size-limit-exceeded-error\/#Tips_to_Manage_Outlook_Mailbox_Size_Limit_Exceeded_Error\" >Tips to Manage Outlook Mailbox Size Limit Exceeded Error<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/www.cigatisolutions.com\/blog\/outlook-mailbox-size-limit-exceeded-error\/#1_Clean_Up_Your_Mailbox_with_Outlooks_Cleanup_Tool\" >#1.
