Every time I use Outlook I need to change SMTP port to 587. The problem is that every time I start the program it restores the default port 25. How can I set the port to 587 permanently?

It shouldn't do that, it should stick. How exactly are you setting that port in OE6? Is this your computer, or a company one? I ask because there may be scripting or GPP that are changing it on reboot. – Ƭᴇcʜιᴇ007 Mar 30 '13 at 14:51
@techie007 it's private pc, but not mine. either way I am sure there is no scripting of any kind. What I do is: Tools -> Accounts -> Properties -> Advanced -> change SMTP port from 25 to 587 -> OK. (I wrote this from memory, because I have no access to this pc right now) – alex Mar 30 '13 at 15:46
Ahh it's resetting when you restart OE even. Silly me, I thought it was happening at reboot. Does it act the same for a new user? – Ƭᴇcʜιᴇ007 Mar 30 '13 at 15:49

This is more of a recommendation than an answer to your issue. I would recommend using a supported email client like Thunderbird or Outlook (Microsoft Office), but if that is not an option, I would recommend reinstalling OE6 which is still available for download.
