The server name of the ContentStore Mail Server (SMTP). This value is read-only.
Upload the certificate
Browse to the SSL certificate and upload it to the ContentStore Mail Server (SMTP).
Important: If you use Office 365 with Exchange (Exchange Online), after you upload the SSL certificate and enable TLS for SMTP, you must enable TLS on the Send connector. For more information, see the Microsoft TechNet article: "Set up connectors for secure mail flow with a partner organization": https://technet.microsoft.com/en-us/library/dn751021(v=exchg.150).aspx.

ContentStore Mailbox cache location
Messages received by the ContentStore Mail Server (SMTP) are stored in this folder before they are processed by the ContentStore Mailbox archiving job. If the Delete archived messages after successful archive operations option in the Exchange journal plan is enabled, messages are deleted from this folder after the archive job completes.
By default, this location is in the software installation path. You can change the path to another location, which can be a local path or a shared network location. If you use a shared network location, you configure it first.
For best performance, follow these guidelines:
Each server must have its own shared network location. For example:
SMTP server 1: \\SMTP\share1
SMTP server 2: \\SMTP\share2

The SMTP server accepts only the messages from the Exchange servers that are configured in this list. If messages come from Exchange servers that are not on the list, the messages are rejected.
If you change an Exchange server IP address, or if you add Exchange servers to the Send connector, make sure that you add the IP addresses to this list.
