Up until today at work we didn’t have any size limits set for our email. I know this is unheard of now a days, but we couldn’t get them approved. We didn’t run into a lot of problems, but would have someone try and send really large attachments once or twice a year which would slow things down for awhile. Today; however, that changed. We had a user try to send an email that had 1.6GB worth of attachments. So once we got Exchange back up and running limits were put into affect.
The problem we saw was this email with the very large attachment was sent and appeared to be stuck in the submission queue on Exchange. There is no right-click delete message when in the submission queue. The only way we found to resolve the issue was to create a new queue folder. Here are the steps we took to do this. Please make note that if you do this you may lose other messages in the queue.
- Open computer services via Start –> Run –> Services.msc
- Locate and stop the Microsoft Exchange Transport Service
- Navigate to the Queue folder location. By default the folder is in C:Program FilesMicrosoftExchange ServerTransport RolesData
- Right click on the Queue folder and rename it. Rename the folder to something like Queue.old.
- Create a new folder and name it: Queue
- Start the Microsoft Exchange Transport Service.
- Confirm email flows in and out of the server.
