Unable to send Outgoing messages!

Hi! .
My company email server has made some changes. Since everyone uses outlook, they have asked them to change a few settings. i.e change the outgoing server value in outlook from 25 to 26… but keep the incoming value same as 110… After this change in the value of outgoing server, I am unable to send any messages. I don’t understand what values i should change in eM client.
Please help! thank you

Open eM Client - Tools - Accounts and try to change the port in SMTP tab.

Thanks a lot… Its working fine now…
