A full mailbox can stop new email arriving. Depending on the sender and mail provider, messages may bounce, queue temporarily or silently fail delivery after repeated attempts.
Common causes
- Large attachments.
- Old sent items.
- Deleted items not being emptied.
- Multiple devices saving copies.
- POP3 settings leaving messages on the server.
- Mailboxes being used as long-term archives.
How to fix it
- Log into webmail.
- Delete old or unnecessary messages.
- Empty Trash, Deleted Items and Junk folders.
- Remove large attachments if no longer needed.
- Check Sent Items as well as Inbox.
- If required, request a mailbox quota increase.
Long-term recommendation
If email is business-critical or needs long-term archiving, Microsoft 365 or Google Workspace is normally a better fit than basic hosting mail. They offer larger mailbox options, stronger search and better business administration tools.
