Chaning SMTP/POP3 settings using VB.NET

Hello All

I have a local email server in my office which downloads email from my pop3/smtp server; all the workstations use office outlook for emails, etc. and are connected to this local server. Accounts for each users are pop3/smtp.

Recently i faced a problem, for some off reason my server went down while i was on holidays and all the email system of my office did not work. Now most of the people working there cannot change the email account properties in outlook, is there a way to change the pop3/smtp setting using vb.net ?

Reason is, that in future, if this kind of thing happens, atleast i have software written in VB.NET which can change the settings for outlook email account to the one on the internet, so they don't have to wait for me to come back to work.

Thanks in advance...!

While I'll have to do some research about changing a user's email profile via managed code, may I also suggest another route? It sounds like the problem you are facing is more of an infrastructure problem and may be solved by running a local DNS server. You could put an entry in the DNS server like:

#The domain name    #the ip of your local server

When the local server goes down, you can then just re-point the dns entry to the new/external IP address like:
mail.mydomain.com   XXX.XXX.XXX.XXX #(external server's ip goes here)

You would point your client workstations to use the internal DNS server and then when the server goes down next time, you can change your DNS entry and everyone will be using the new server without running something on each local machine.

I'll check into changing an email profile programmatically, but please let me know what you think about the DNS server solution.


Well, it looks like you might have to figure out how to edit PST files to change settings like this. I was hoping the profile settings (i.e. smtp and pop3 settings) would be stored somewhere in the registry. Unfortunately, it looks like they are stored in the personal folder (PST file) along with everything else about your profile.

If you are still set on editing the settings programmatically, I would recommand taking a look at:

If you want to edit PST files, you will need to learn a lot about extended MAPI and that URL is a pretty good resource. It looks like the URL above has a tool that lets you visually see what's in your PST file. Unfortunately, I'm not familiar with MAPI programming, so I'm not going to be much help... sorry.

Please let me know what your final solution involved.

I have doing research for the past two days my self, and it seems that there is no way of changing the email account via visual basic.net - and to be really honest, i really like the idea of having the dns enterie. Although I do have a local DNS server which can be changed remotly without any change, and this method is less head ache compared to chaning the email account. I think I will go for this - thanks!
