Hi, we are using Dynamic CRM 2016 On-Prem Version 8.1

I am getting this error message since last Friday. 

"The mailbox location could not be determined while sending the email message "Test Message" through the mailbox. The owner of the associated email server profile Exchange has been notified. The system will try to send the message again later."


Below is the image for our exchange profile setup. Please let me know how to get rid of the error?

    Hi Partner

    You will see this alert if your email server profile (Settings > Email Configuration > Email Server Profiles) is configured to use the Auto Discover Server Location option but auto discover cannot detect the location of your mailbox. If this issue occurs, check with your Exchange administrator to verify your network is configured for auto discover. You can update the email server profile and click No for Auto Discover Server Location. Then provide the Exchange web services URL for your Exchange deployment. For example: ExchangeServerName/.../Exchange.asmx.

    Here's reference link which can be referred for this Error
