This is a very unique scenario that will not be easy to fix and may require relocating where you store your SmarterMail data for that domain. I recommend submitting a ticket so you can work with an agent on getting this issue fixed.

Hi Matt, Thanks for the reply. I resolved the issue.
 
It might be helpful for other users so I share my solution:
I recently moved SM 15.7 from server 2008 to server 2016 and also changed the domain path from C:\domains into D:\Smartermail\Backups\Domains. I thought it was not the issue but actually it was the issue.
Stop SM Service, I copy the domain folder from D:\Smartermail\backups\ into D:\Domains, Change path in domainList.xls (location: C:\Program Files (x86)\SmarterTools\SmarterMail\Service) start the service and Issue is resolved. Its causing problem because path is too long.
