Engable TLS in Exchange

Hi,

We have made some changes to the exchange on the Security right and need to change them back .. stupidly I have lost the paper that I noted the previous setup on.

I have got most of it working again but I'm unable to get exchange to accept the TLS emails from other companies especially from the bank.

The Directors arent happy and I need to resolve this ASAP.

Does anyone have any advice?

Thanks

On the Receive Connector from the internet ensure that the following is enabled:

Transport Layer Security (TLS)
Basic Authentication, plus Offer basic...
Exchange Server Authentication
Integrated Authentication.

NOT Externally Secured.

If you have domains configured for TLS, then also enable "Enable Domain Security".

Once you have it working, using snipping tool to make screenshots!

Hi,

I already have these enabled as you can see from the screen shot.

I'm testing it using MXTOOLBOX

Thanks

You should have said it was an SBS server.
SBS doesn't use the Default Connector, it uses its own Connector. You need to run the fix my network wizard to correct the configuration of that.

Once you have done so, from a machine external to your network telnet to port 25 and issue a EHLO and see if STARTTLS is on the list of commands.
