Outlook and proxy?

Question

proxy

Our educational institution connected the Internet through a proxy server, and now Outlook does not work. How can this be resolved?

Answer 1

Give outlook minimal access so it doesn't get denied.

Answer 2

When connecting Exchange, Outlook freely passes the proxy (the main thing is that it passes authentication). Because uses https.
If you use Outlook to connect to yandex/mail/gmail, then the answer to how to make Outlook work through a proxy will be no way. (We do not touch on the issues of port forwarding, ssh port forwarding, and other things, if a person asks a question on a toaster, he is unlikely to master it in the next five years).
There are two options left:
* Refuse the client in favor of the web muzzle
* Ask the admin to open a direct connection (set up nat) on ports 143, 110, 25 (underline as appropriate) to the required yandex / mail / gmail resources (underline as necessary)

Answer 3

For example, raise a local proxy server that will perform port forwarding through the parent. In 3proxy, you can do something like this configuration:

auth iponly
internal 127.0.0.1
allow *
parent тип_прокси адрес_прокси порт_прокси
tcppm 25 IP_адрес_SMTP 25
tcppm 465 IP_адрес_SMTP 465
tcppm 587 IP_адрес_SMTP 587
tcppm 110 IP_адрес_POP3 110
tcppm 995 IP_адрес_POP3 995
tcppm 143 IP_адрес_IMAP 143
tcppm 993 IP_адрес_IMAP 993
...

and set 127.0.0.1 in hosts for SMTP/POP3/IMAP server names (this is necessary for TLS to pass without swearing at a mismatch between the host name and certificate)
