Certificate Exchange 2013 Connector Proxy client 465
Hi all, I have an Exchange 2013 when I set up a mail client for IMAP and SMTP Insurance (465), I get an alert on the client and show me the self-signed server certificate.

I have a certificate trusted third party, I have allocated these services:

IIS, SMTP

This is the third trusted certificate


Microsoft Exchange
-----------------------------
Certification Authority. Signed certificate
Issuer: xxxxxxxxxxxxxxxxxx
State
Valid
Expires: XXXXXXXXXXXXX
Expires: Renew
Assigned to services
IIS, SMTP



Then there are the default certificates that brings the server, are these

Microsoft Exchange
--------------------------------
Signed Certificate
Issuer: CN = xxxxxx
State
Valid
Expires: xxxxxxxx
Expires: Renew
Assigned to services
IIS, SMTP


WMSVC
------------
Signed Certificate
Issuer: CN = WMSvc-XXXXXXX
State
Valid
Expires: XXXXXX
Expires: Renew
Assigned to services
NONE


Microsoft Exchange Server Auth Certificate
-------------------------------------------------- ------------
Signed Certificate
Issuer: CN = Microsoft Exchange Server Auth Certificate
State
Valid
Expires: XXXXXXX
Expires: Renew
Assigned to services
SMTP


ACTIONS THAT HAVE TO DO TO PROVIDE mail servers CERTIFICATE OF TRUST THIRD PARTY IN CONNECTION SMTPS mail clients 465

Hi,

According to your post, I understand that return an alert self-signed server certificate when configure IMAP client.
If I misunderstand your concern, please do not hesitate to let me know.

How about send and receive message in IMAP client?

Please run Get-ImapSetting | FL to get details about IMAP configuration in your environment, especially SSL or TLS, and port.
Also check the authentication method, port and permission setting in receiver connector.
Meanwhile, please run Get-ExchangeCertificate | FL view the configuration, and refer to below link to know which certificate is used for SSL:
