The email system will notify you when you reach certain thresholds. An email will be sent when the quota is reaching its capacity, informing you of the current usage. If you go over quota, you will receive an email twice a day, at 8 a.m. and 4 p.m., warning you that you have gone over quota and informing you of the quota usage in the message. When a mailbox exceeds its allocated storage by more than 200 MB, the mailbox is closed and will no longer receive email. At that time, when email is sent to you, a non-delivery receipt is generated and returned to the sender indicating that the email could not be delivered because your mailbox is over quota. At the time the mailbox is closed, an explicit warning message is deposited in the mailbox making you aware of this fact.
- When your mailbox reaches 90% of your email storage limit, you will receive a message stating "Your mailbox is almost full. Please reduce your mailbox size. Delete any items you don't need from your mailbox and empty your Deleted Items folder." as a precautionary warning. Your email will continue to function correctly at this time.
- When your mailbox has reached your email storage limit, you will receive a message stating "Your mailbox can no longer send messages. Please reduce your mailbox size. Delete any items you don't need from your mailbox and empty your Deleted Items folder." You will be unable to send email until you have freed up some space, but you will continue to receive emails during this time.
- When your mailbox exceeds your email storage limit by over 200 MB, you will again receive the "Your mailbox is full." message. You will be unable to send or receive email until you have brought your email usage back under the storage limit.
