What are the mailbox limits?
500 MB Warning Level
650 MB Prohibit Send
750 MB Prohibit Send and Receive
This means that once your mailbox reaches or exceeds 500 MB you will receive a warning that you have exceeded the mailbox limitation. When
your mailbox reaches or exceeds 650 MB you will not be able to send any messages. When your mailbox reaches 750 MB you will not be able to
send mail and any mail sent to you will bounce back to the sender.
