What Happens When Your Email Disk Space Is Full?
At iCoreHosting, and just like most hosting providers in Malaysia and internationally, every email hosting account comes with a disk space limit. When that limit is reached, you will no longer be able to send or receive emails.
This is a standard behavior across all major email platforms. Once your storage is full, the system cannot save new messages or send outgoing ones until space is cleared or increased.
What Will Happen
1. You Cannot Send Emails
-
Sending attempts will fail immediately.
-
You may see error messages such as:
-
“Mailbox full”
-
“Quota exceeded”
-
“Cannot send message”
-
2. You Cannot Receive Emails
-
Incoming messages will be rejected automatically.
-
Senders will receive a bounce-back email like:
-
“Recipient’s mailbox is full”
-
“Delivery failed due to storage limit”
-
-
These emails are not saved — they are typically lost unless resent.
