Outlook 2010 client not able to connect to provider

nicolebaumeler
Hello to all,
 
Situation:
I have an outlook client (2010) in the internal network that has to connect to an external e-mail provider to send and fetch e-mail.
The Sophos XG is in transparent Mail delivery mode (not MTA).

I have a business application rule in place that scans traffic: imap/imaps/pop/pops/smtp/smtps (the services to scan are predefined and can be selected by checkbos).
 
Until now the e-mail provider delivers mail still unencryptet, so POP = 110, SMTP = 25 and everything is working fine: the outlook client connects to the e-mail provider, send and receive e-mail is no problem.
 
 
By end of this month the provider will switch to encryptet mail and turn off unencryptet protocols:
POP will be POPS = 995
SMTP will be switched to SMTPS = 465
 
The problem is: whenever I change the outlook client settings, the client is not able to connect to the provider anymore.
 
I tried to implement different network and also business application rules that would allow the client to pass on the given ports (995/465), but nothing I tried is working.
Please help!

    Hi Ian

     

    You are right, when I do not set any time filter, I can see mail logs.

     

    Situation: Outlook was closed when I stopped working last nicht at 3am something and just opened right 10 minutes ago, around 11:40.

    I opened the mail logs and saw all mails that arrived between 3am and 11:40am, last arrived at 11:39 exact time (-> see on the printscreen below, it was the same as it is after the test)

     

    1. I changed the outlook settings to SSL (same as described before)

    2. Tried to establish connection to the server -> test connectivity in outlook -> see below

    3. Receive the same error as always -> see below

    4. refreshing the mail logs -> no activity (of course not)

    (last entry is the same as I saw at 11:40 when the program was initially opened)

     

    5. Switched back the outlook settings to unencrypted -> Connection successful, Mail passes (11:46h)

     

    I am so **** ... what is blocking me from beeing able to connect...???

    Hi Nicole,

    I know this is not much help to you. Getting mail to work correctly took me some time, I could get Mac mail or outlook but not both. After much trial and error and a number of software updates from both MS and Sophos I have my wife's Mac mail and outlook actually agreeing to the amount of messages.

    At this stage I will have wait until one of the more experienced XG support people review your issues.

    Regards

    Hi Ian

    Thank you for your reply!

    Can you please tell me what is happening now?

    Is someone of the more experienced XG support people reviewing my issue automatically or can I just wait and hope that probably someone looks at it? Or maybe never will...?

     

    Thank you for short answer!

    Thank you for all the time and effort you took for me!

     

    Best regards

    Nikki

    Hi Nicole,

    if you want a quicker fix than relying on the forums you need to log a support case.

    I fixed the SSL issue.
    I am a little bit surprised that obviously no other user ever ran into that issue.... and first of all let me say: the issue has not been caused by Sophos.
    The issue has been Windows 7.:
     
    Windows 7 does not natively support TLS 1.1 and TLS 1.2
    I had to tune the registry of Win7 so TLS 1.1 and TLS 1.2 are working.
