Exchange Sync. Setup can only work with Exchange Online as this is hard coded in a txt url

If your customer is using an Exchange Server OnPrem, then out of the box Exchange Synchronization via web services does not work.

Repro:

setup Exchange Server OnPrem
populate the Office 365 Authentication mail address with the E-mail address that is hosted on the local Exchange Server
press Validation Exchange Connection via Process in Exchange Sync. Setup.

Fiddler does show it tries to connect to Exchange Online. There are partners / customers that do own a local Exchange Server OnPrem.

In Exchange 2018, Dynamics 365 BC up to release v14, it is easy to update the following code:

VAR

Service@1000 : DotNet "'Microsoft.Dynamics.Nav.EwsWrapper, Version=11.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.Microsoft.Dynamics.Nav.Exchange.ExchangeServiceWrapper";

ProdEndpointTxt@1002 : TextConst '@@@={Locked};ENU=outlook.office365.com/.../Exchange.asmx';

ExpiredTokenErr@1003 : TextConst 'ENU=Trying to reconnect. Please close and reopen the add-in.';

To:

VAR

Service@1000 : DotNet "'Microsoft.Dynamics.Nav.EwsWrapper, Version=11.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.Microsoft.Dynamics.Nav.Exchange.ExchangeServiceWrapper";

ProdEndpointTxt@1002 : TextConst '@@@={Locked};ENU=exchange.local/.../Exchange.asmx';

ExpiredTokenErr@1003 : TextConst 'ENU=Trying to reconnect. Please close and reopen the add-in.';

For BC150, BC160 and later we added an event you can subscribe to. The code adjustment (not a platform fix) will be part of July 2020 CU.

Thanks.
