The E-mail Router service could not run

Not sure why but had the e-mail router decide it needed a vacation.  The message isn't clear where the state XML file is located but neither the service or the configuration tool would start,

After doing the Repair, rebooting the server I was still stuck at no luck.  I finally then decided to uninstall and re-install the email router.  Even after that the error still occurred.  It wasn't till I finally deleted the e-mail router folder in Program Files that I was able to re-install and have things run.

Of course the configuration was empty after the delete of the folder and re-install - the config on this server was simple so it wasn't really a big deal to re-configure.  I did take a few minutes after I set it back up to find where the config is stored in case this happens again.  First, the configuration file can be found by default at C:\Program Files\Microsoft CRM Email\Service\Microsoft.Crm.Tools.EmailAgent.xml

The state file referenced in the error below is also located in the service folder.  Possibly if I looked at that folder before I might have been able to make it happy. 

I have now backed up both of these files to save a copy so I hopefully wouldn't have to start from scratch if this happens again.

I think it would be great for the e-mail router to have an real support for Export Configuration and Import Configuration

Just confirming that this exact issue happened in my environment -- backing up the file structure, uninstalling, removing the folder from Program Files and then reinstalling DOES fix the issue - everything else failed. However, simply copying back in your XML files does not add the customized setting back to your deployment. And yet -- it is all still working like it did before...

Oh how I love CRM and it's support...

I had exact issue as described above. Delete file C:\Program Files\Microsoft CRM Email\Service\Microsoft.Crm.Tools.EmailAgent.xml

then run rebuild. I did not uninstall. Prior to deleting, I opened file in notepad and it was blank. If you don't delete if first, repair won't replace it.

just delete the file, it then re-creates it

Had the some issue. Renamed Microsoft.Crm.Tools.EmailAgent.SystemState.xml and restarted the Microsoft CRM Email Router service from services.mmc. That worked for me.
