Error 431: Insufficient Storage

What Is Causing This Error?

‘Error 431: Insufficient Storage’ typically occurs when the recipient’s mail server is running low on storage space, preventing it from accepting new emails. This situation can arise due to the mailbox reaching its capacity limit or the server itself facing storage constraints. It reflects a temporary issue where the server’s inability to allocate necessary resources results in the rejection of incoming emails.

Resolving the Error – Solution

To resolve this error, the recipient needs to take action to free up space in their mailbox. This can involve deleting old or unnecessary emails, compressing large attachments, or archiving emails to an external storage solution.

On the server side, administrators may need to increase storage capacity or manage resources more efficiently to accommodate incoming emails. Once sufficient space is made available, the server should be able to accept new emails without returning error 431.

That’s it! Now you know the common causes of the 431 error and how to resolve it.
