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.
