Hi,

I think the closest log you're looking for is the Administrative log that you can find in your log directory or from the log viewer in the "Troubleshooting" section when you're logged as admin in the web UI.

It contains login attemps (success or failed for SMTP, POP, IMAP, WEB, etc)

Maybe you have to set it to "Detailed" level, I'm not 100% sure though, maybe "Normal" is sufficient.

Hi,

Thanks a lot Sebastien. The second part regarding the web admin UI does help a lot since I realized it was set to disabled. I've put it in Normal for now. However, I have a somewhat newbie question, where exactly is the default location of the Administrative log? Is that related to the Administrative events in event viewer? 

Hello, 

Sébastien is correct that the logs are stored at this location. There are two other location that some logs are stored ( Autodiscover, SignalR, .. ) can be found in the MRS folder. 

C:\Program Files (x86)\SmarterTools\SmarterMail\MRS\App_Data\Logs

And the service start/stop log

C:\Program Files (x86)\SmarterTools\SmarterMail\Service\Settings\Logs

Thank you
