Hello,

 Just in the process of getting Exchange server 2013 setup on a windows Server 2012r2 environment I have set it up and was able to send and receive email, but then it stopped working I check the services and saw "MSExchangeMailSubmission" service was not running i have tired to start it but with no luck been messing around for quite a few hours and have read over many forums. any help would be much appreciated. 

i currently have 2 mailbox users, and am able to access thw OWA page externally and am also able to set up the accounts in outlook. when i do send an email it staying the the drafts folder. 

Thanks 

if you need more info let me know.

Hi 

Please check the event logs for relevant errors
Check the service is running on which account ( local or admin). Try changing to admin account and see the results

If none of the above works then it will be surely an issue with MSExchangeMailSubmission.exe.config since you say its all new fresh installation
In this case just replace this MSExchangeMailSubmission.exe.config file from the setup and see the results
