hi all,

i have a connector TLS to partner , we're both hosted by 0365 , veirfication on connector was passed on sending email to partner. but the test  on outlook failed with this error state
your message couldn't be delivered because there is a partner connector configured that matched the message's recipient domain. The connector had either the RestrictDomainsToIPAddresses or RestrictDomainsToCertificate set.BL2FFO11OLC003.mail.protection.outlook.com gave this error:
TenantInboundAttribution; There is a partner connector configured that matched the message's recipient domain. The connector had either the RestrictDomainsToIPAddresses or RestrictDomainsToCertificate set

 >>>Connector from 0365 to Partner : Always use Transport Layer Security ‎(TLS)‎ and connect only if the recipient’s email server certificate is issued by a trusted certificate authority ‎(CA)‎, and the subject name matches this domain: vdnet-com.mail.protection.outlook.com

>>>>Connector from Partner to 0365:Security restrictions
Reject messages if they aren’t encrypted using Transport Layer Security ‎(TLS)‎, or the subject name on the certificate that the partner uses to authenticate with Office 365 does‎'t match this domain name: partner-com.mail.protection.outlook.com
MY domain name vdnet-com.onmicrosoft.com

Many Thanks in advance

Well you cannot really have a certificate matching outlook.com or any .onmicrosoft.com domain, so adjust that part in the connector setup.
