C# import/export data to Mailclient

I am currently working on a program to export/import data from other mail clients to outlook.
So far it seems I have two options available.
I learn how to write to a pst file so I can easily import the necessary data.
I create a different, self-made connection.
I am not asking which one I should use but rather on some advice because so far while planning I ran across a few things with each method that might turn out to be too much of problem.
So far I couldn't find an existing library that allows writing to a .pst file. I am lucky to finally have found a library that allows reading the pst file that is open source.
I haven't found a way yet to programmatically create a new mail item in the inbox. I have been able to create a new email that can be sent but no email yet that is "incoming".

have you looked into outlook interop?
depending on how your application will function it is a great way to interact with outlook at a high level, you can easily create mailItems, calendar, memos etc.

My recommendation would be to create a temporary IMAP account on whatever IMAP server you like best (whether that be GMail, Yahoo!Mail, some other free IMAP account, or a local Exchange/Dovecot/etc server).
Then, once you've got that setup, export mail from Mail Client X to the IMAP server and then add the temporary IMAP account to Outlook and copy them all into your Outlook folders.

Get Tfs notifications/alerts in c#

I am trying to create a "wierd push notification".
Every time there is a new task/request in TFS, I will get a notification in my C# program, so I can take the necessary actions...
The problem is, that as I see TFS2015 only supports sending notifications and alerts to e-mail addresses...
If there would be a solution what can notify (eg. with events) my code, that I have recieved a new e-mail... (we are using Outlook)
Anyway, if anyone have a better solution do not hold it back!

To achieve what you want, you can develop a VSTO Add-In for Outlook to listen to the Outlook. Then you write code directly against the ThisAddIn class in your project.
Get start of the VSTO Add-In for Outlook, you can refer to: https://msdn.microsoft.com/en-us/library/cc668191.aspx

You can create a Server Side plugin to track the server event and send notification: TFS Event Handler for Team Foundation Server.

Outlook Interop Security

I am writing a C# Console application which shall be able to search through my emails.
I use the Interop Outlook dll to connect and can access the emails fine, but I always get a popup windows which asks me if I want to allow access to Outlook.
I understand that this is a secruity dialog and is needed so viruses cannot access my mails. I have already written an Outlook Add In in the past and never got the dialog. I guess this is because the code was executing from inside Outlook.
Is there any possibility do store my console app id and always grant access?
If there is no way around the dialog, is there any other way to search my local emails withing a C# console application?
The Systems specs are:
Server 2012 R2 Datacenter,
Visual Studio 2013 update 4 and
Outlook 2013

You see the standard security prompt in Outlook. You can do the following to avoid it:
Use the Security Manager component for supressing the security prompts in Outlook.
Use a low-level API which doesn't generate such security prompts - Extended MAPI. Or any other third-party wrappers around that API such as Redemption.
Deploy Outlook security settings (for administrators).
You can read more about all of these ways on the Outlook "Object Model Guard" Security Issues for Developers page.

We encountered this issue on a recent Windows Server deployment. The server has Office 365 installed and upto date Symantec Antivirus, for this reason, we overrode the default Programmatic Access Security Setting (while we investigate the Antivirus detection issue).
In Outlook go to File -> Options -> Trust Center -> Trust Center Settings -> Programmatic Access
[UPDATE]: After performing an update on the Antivirus Software and downloading the latest definitions, the status within Outlook changed to "Valid".

integrating Outlook with c#

is it possible to integrate outlook with my c# program without having Microsoft office installed?

It depends on what functionality you are trying to achieve?
It also depends on your environment.Do you have access to exchange server?
For example, If you want to create appointments in outlook client for individual user, you can very well make use of webservice provided by Exchange server. However, it works starting with outlook 2007.

In a word, no. If you want to call an Outlook dll you will need Outlook installed.
Perhaps if you describe what you need to do there may be an alternative approach, such as calling Exchange Server as suggested by Edwin.

Disable Outlook Security Message Box

I am developing outlook 2007 add in, and facing problems with Outlook Security MessageBoxes.
I know that i can disable it from the trust center and set allow programmatic access to true,
but i want to disable it by code.
How can i disable Outlook Security MessageBox by code?
Note: I am using C# and VSTO.

Ok,
The security guard pops up when you try to access certain properties of the mail mainly around the email addresses. You can use mapilib to stop it or use redemption's safe mail item. or
You can use the mail items PropertyAccessor to gain access to the underlying Mapi properties
For the "TO" you need PR_EMAIL_ADDRESS (or PR_SMTP_ADDRESS)
mailItem.PropertyAccessor.GetProperty("http://schemas.microsoft.com/mapi/proptag/0x3003001F");
I would suggest that you download Dimitry's Outlook spy its "the" tool if you are developing Mapi/outlook etc.
You can then look up the Mapi properties and their ids to get the others
