This error is due to having too much mail in your account or the quota size was set too low when the address was created in cPanel.<\/p>\n\n\n\n<p>Before making any changes, you can check your current mailbox usage by going to the Email Accounts section in cPanel. From there, you\u2019ll see how much space each account is using and whether it has exceeded its quota.<\/p>\n\n\n\n<p>To fix this issue, one option is to simply delete emails to lower the size of your existing mail box. Alternatively, you can increase the mailbox quota directly within cPanel if your hosting plan allows for more space. If you\u2019ve already maxed out your mailbox quota, it may be time to upgrade your hosting plan.<\/p>\n\n\n\n<p class=\"alert alert-success extra-bold\">Growing fast? That\u2019s a good sign. <a href=\"\/support\/amp\/upgrade-downgrade-hosting-plan\/\">Upgrade your hosting plan<\/a> to get more space and keep your business running smoothly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What \u201cMailbox Quota Exceeded\u201d Means?<\/h3>\n\n\n\n<p>Email providers assign a specific storage quota to every mailbox. This includes all emails, attachments, folders, and sometimes even calendar items. When your mailbox hits this cap, the system will stop accepting or sending messages\u2014triggering the \u201cquota exceeded\u201d warning.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"#increase\">Increasing Email Quota in cPanel<\/a><\/li>\n\n\n\n<li><a href=\"#error\">Cannot Change MailDir Size!

Another helpful step is <a href=\"https:\/\/www.inmotionhosting.com\/support\/email\/imap-archiving\/\">archiving older emails<\/a> using your mail client\u2019s archive feature, allowing you to store them locally or on an external drive instead of the server.<\/p>\n\n\n\n<p>If your storage needs continue to grow, upgrading your mailbox quota might be necessary, which can be done by <a href=\"https:\/\/www.inmotionhosting.com\/contact\">contacting InMotion Hosting<\/a> or your IT administrator to discuss available upgrade options.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"increase\">Increasing Email Quota in cPanel<\/h2>\n\n\n\n<ol class=\"wp-block-list article_list\">\n<li><a href=\"https:\/\/www.inmotionhosting.com\/support\/edu\/cpanel\/how-to-log-into-cpanel\/\">Log into your cPanel<\/a>.<\/li>\n\n\n\n<li>Click on the <span class=\"strong\"><strong>Email Accounts<\/strong><\/span> icon under the email heading.
