  • Exchange Certificates for Outlook Anywhere, and Attachment Size Growth

    I have two questions..

    1) Do a public certificate from some certificate issuing authority(like go daddy) is a must for enabling outlook any where in exchange 2007?please explain how it should be done if a public certificate is needed..

    2) I have a problem when i send mail from my outlook to any outside domain,it sends from exchange to pop3 server but the size of my mail is getting heavily increased and its not getting send..its just retrying in the queue..

    for example, if i send a mail with 4MB attachment when it reaches my pop3 server,its showing 7MB size and if i send a mail with 7MB attachment when it reaches my pop3 server,its showing 9 ya 10 MB size

    Am using exchange pop3 v 5.0 as my pop3 server.

    Hoping to get hear from you guys soon..

    Some people will tell you a public certificate isnt needed but IIRC the Microsoft recommendation is to use one. There are plenty of instructions on getting one out there -- Sembee has a very good set.

    Why are you sending from Exchange to POP3 and not using SMTP delivery - either via a smarthost or direct?

      Thank you..for the reply..

      I am using exchange pop3 v.50 software to send mail and through that via SMTP to my smart mail.when it comes to the internet queue in exchange pop3 after all rules are applied..this increase in size is shown..Is it because exchange add some information about destination and source and all??

      Is it common ya..some problem is there..

        Can you confirm you are using the POP3 software for OUTGOING mail?
        If so, Why?

          Using the self signed certificate issued by Exchange for Outlook Anywhere is not supported. If you are in a position to use Outlook Anywhere then you can use Exchange as it was designed - SMTP delivery. POP3 connectors of all descriptions are junk.

          The instructions for installing the certificate that was mentioned above are here:

          With regards to attachment size increasing, that isn't uncommon. It depends on the encoding used. The growth would seem a little excessive, which may well be a sign of something else interferring with the traffic. However based on what you have written it is hard to say more.
