I have had a couple issues lately where end user's email worked fine but when someone sent them a calendar invite they could except it and it seemed ok, but a meeting change or cancelation would not go through and the sending user would get a bounce back that the mailbox was full. I questioned the Exchange people on here and after a little research it turned out the be the dumpster on the two users was full. I expanded the respective dumpsters and everything fell back into place. Now, I am wondering how many other users are approaching similar issues. Is there a script I could write that would report everyone's dumpster size along with how much space they have been allocated? Maybe something I could run on a regular basis to monitor for this usual issue. All help is welcome. I was thinking powershell, but I am open to all ideas.
