Exchange 2013 Mailbox Limit Exceeded & Unable to Send Emails


I have an end user who was reporting that they had 3 emails in their "Sent Items folder that's been there for a few hours.

Upon checking I realized they reached their mailbox quota. However upon deleting most of their emails in the outlook client the emails still wouldn't send even after opening them and clicking send again.

I proceeded to check their account in Exchange Admin Center and saw that it was still showing over its limit. Its been about 3 hrs now and the limit hasn't updated in exchange.

If there something i missed here, this is the first time i'm seeing this happen.

Did you soft delete the items from the inbox (are they still present in the Deleted Items folder)? If this is true then that would be the reason why you are still getting this over limit message. The delete items folder it part of the overall mailbox size. you also need to remove items from Deleted Items folder as well.

Hi WIll,

That was the first thing i checked actually and included all other sub folders in the inbox.

No emails period.
I would go into mailbox cleanup and check mailbox size.    Make sure you are looking at the server data tab.     Check problem folders containing most data....

Does this same issue happen from OWA? If you create a new Outlook profile do you get the same results? Sometimes the caching of the OST does not update properly to Exchange if the OST or profile has issues.

for time being, I would give user some more storage.

Can I ask why you have only 100MB quota. Best practice is to have a 2GB mailbox or similar and set limits defined by global policy.

Currently these guys aren't required to have more than 100MB as they don't have to store emails.

Came to the company and met that policy inplace.

Deleting mails wouldn't increase the size limit in exchange server it just create whitespace instead which you can remove using eseutil /d command. In order to increase the size limit you can either Create a New Database and move the content into this or Change Registry settings value to increase the configured size limit of Exchange.
