Hi @all
I have noticed since a few days that we can not send emails from our test system. Since when exactly it no longer works I can unfortunately not say, the system (version 5.6) is not used daily.
I get the following message:
"72999628", "2023-07-31 10:40:49", "Error", "MessageBus", "61012", "ConnectionError", "ExchangeWebServicesOrigin", "61012 Exception from message source username@domain.com: System.Web.Services.Protocols.SoapException: The primary SMTP address must be specified when referencing a mailbox.
The account has an MS license, has a mailbox and can access it.
I have already checked the settings in "ConnectionStringEditor.exe" and compared them with the working systems. The settings are identical.
However, when I run Setup.exe and want to reconfigure, I can only select the installation with the "Recover" option. No other option is active.
Do you have a tip here where to look?
Best regards
Stefan
