Multiple LS Storage Service 32054 errors

It seems that everything is working, but I have many errors in Event Log.

************************************************************************

Storage Service had an EWS Autodiscovery failure.

UnsupportedStoreException: code=ErrorIncorrectExchangeServerVersion, reason=GetUserSettings failed,smtpAddress=username@domain.com, Autodiscover Uri=https://autodiscover.domain.com/autodiscover/autodiscover.svc, Autodiscover WebProxy=<NULL> ---> Microsoft.Exchange.WebServices.Data.ServiceRequestException: The request failed.

Cause: Autodiscovery Uri was not correctly configured or unreachable, that there is a problem with the Proxy, or other errors.
Resolution:
Check event details.  Check autodiscovery Uri is properly configured and reachable. Check that proxy setting is properly configured and reachable.  Validate Lync to Exchange Autodiscovery configuration by following the trouble shooting guide. If problem persists, notify your organization's support team with the event details.

Not sure why it is trying to use https://autodiscover.domain.com/autodiscover/autodiscover.svc. Is this correct?  I thought it should behttps://lyncdiscover.domain.com/autodiscover/autodiscover.svc orhttps://lyncweb.domain.com/autodiscover/autodiscover.svc.

If I run Get-CsService -WebServer | fl  autodiscover*, I receive the following output:

AutodiscoverServiceExternalUri : https://lyncweb.domain.com/Autodiscover/AutodiscoverService.svc/root
AutodiscoverServiceInternalUri : https://lyncpool.domain.local/Autodiscover/AutodiscoverService.svc/root

As I said, everything looks good and working. Anyone has any ideas what that is?

Thank you.

Thank you. Eric.
