Office 365 passwords may expire and need to be updated. Has the password expired?

Hi,

If the code is working fine and suddenly get stopped, I don't think it's due to the code issue.

Have you tried to login your Instance normally or is there any update on your org? If your org has been updated to V9.0. You need to set Security as TLS12

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

Related cases could be referred by following linkage:

You could also check the follow similar cases to check your coding while I don't think they may be the root cause of your issue.

Hi,

Please use below snippet for Organization service connection

for Dynanics CRM version 9 above ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12; //TLS1.2 is required for v9 and above CrmServiceClient con = new CrmServiceClient("connectionString"); var service = (IOrganizationService)con.OrganizationWebProxyClient != null ? (IOrganizationService)con.OrganizationWebProxyClient : (IOrganizationService)con.OrganizationServiceProxy; for version <8 and >9 CrmServiceClient con = new CrmServiceClient("connectionString"); var service = (IOrganizationService)con.OrganizationWebProxyClient != null ? (IOrganizationService)con.OrganizationWebProxyClient : (IOrganizationService)con.OrganizationServiceProxy;
