A local storage problem affects the app or device, even when the server mailbox still has available space. Deleting a message in the client may not free local space immediately if the app keeps a local copy or cached data.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Attachment size limit:<\/strong> A message can be rejected because its attachment is too large. This is separate from the total amount of email stored in the mailbox. Deleting older messages will not make an oversized attachment smaller.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Provider throttling:<\/strong> A provider may temporarily restrict sending or receiving activity. This can look like a general email failure, but deleting messages does not remove a temporary sending restriction. SMTP error codes can help identify why a message was not delivered. See <a href=\"https:\/\/mybox.com\/help\/ro\/baza-de-cunostinte\/coduri-de-eroare-smtp-si-o-lista-de-coduri-cu-explicatii\/\">SMTP error codes and their meaning<\/a> for an explanation of these server responses.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_check_the_server_mailbox_quota\"><\/span>How to check the server mailbox quota<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Start with the mailbox itself, not only the error shown by the email app. Sign in to webmail or the mybox dashboard and open the email or mailbox area. The <a href=\"https:\/\/mybox.com\/help\/ro\/baza-de-cunostinte\/informatii-despre-casuta-postala\/\">mybox Email section<\/a> is used to monitor resource usage and manage mailboxes.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Open the mailbox or Email section.<\/li>\n\n\n\n<li>Look for storage usage, quota, or mailbox size information.<\/li>\n\n\n\n<li>Compare the used space with the mailbox limit.<\/li>\n\n\n\n<li>Check folders that may contain large amounts of data, including the inbox, sent mail, and trash.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">If the server shows that the mailbox is full, the email client is reporting a server-side condition. Changing the client settings alone will not increase the mailbox quota.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_check_local_storage_in_the_email_client\"><\/span>How to check local storage in the email client<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Open the affected email client and review its account, storage, or data-file settings. Check how much space the app uses on the device and whether it downloads full messages or attachments for offline use. The exact setting name depends on the client.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the server quota has available space but the client still reports a full mailbox, compare the error in webmail with the error in the app. A problem that appears only in the app is more likely to involve local storage, synchronization, or the client\u2019s data file than the server quota.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Safe_ways_to_free_mailbox_space\"><\/span>Safe ways to free mailbox space<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Find large messages.<\/strong> Review messages with large attachments first.

Permanently remove them if the mailbox interface provides that option.<\/li>\n\n\n\n<li><strong>Archive selectively.<\/strong> Archive messages when the archive remains within the same mailbox quota. Archiving is useful for organising mail, but it does not reduce server storage if the archived messages are still stored in that mailbox.<\/li>\n\n\n\n<li><strong>Allow synchronization to finish.<\/strong> When deletion is made in a third-party client, wait for the client to synchronize with the server, then check the quota again in webmail or the mybox dashboard.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">For a broader storage review, the <a href=\"https:\/\/mybox.com\/help\/ro\/baza-de-cunostinte\/curatenia-de-primavara-a-casutei-postale-cum-sa-verificati-sa-arhivati-si-sa-stergeti-in-siguranta-datele-vechi-pentru-a-elibera-spatiu\/\">mybox mailbox storage audit<\/a> covers auditing, archiving, and deleting old data.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_deleting_messages_can_and_cannot_fix\"><\/span>What deleting messages can and cannot fix<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Cause<\/th><th>Can deleting mailbox messages help?<\/th><th>What to check<\/th><\/tr><\/thead><tbody><tr><td>Server mailbox quota reached<\/td><td>Yes, if deletion is synchronized and trash is emptied.<\/td><td>Quota usage in webmail or the mybox Email section.<\/td><\/tr><tr><td>Local client storage full<\/td><td>Sometimes.
