By some googling I found few third party COM libraries to avoid this. But I am looking for a solution which don't require any third party COM library.

Sorry, I have had that annoying issue in both Outlook 2003 and Outlook 2007 add-ins, and the only solution that worked was to purchase a Redemption license. In Outlook 2007 that pesky popup should only show up if your firewall is down or your anti-virus software is outdated as far as I recall.

I ran into same issue while accessing sender email address for outlook mail item. To avoid 'security alert' do not create new Application object, instead use Globals.ThisAddIn.Application to create new mailitem.

Try this
Tools-->Macro-->Security-->Programmatic Access
Then choose Never warn me about suspicious activity.

You won't find it. Kasper already pointed out the only solution that I know of. Redemption has been the only thing that has kept the Outlook plug-ins and code to work. I have done commercial Outlook add-ins for Franklin Covey. We explored a lot things, but Redemption was the only thing that got us over this hurdle.

If your application is not a Outlook plug in you can look at MAPI to read data from the inbox
I can't point you anywhere except Google and cannot guarantee that anything you find there will be any good. Jaguar x-type gps update. Even if you can find something, it is likely to be 2 - 3 years out of date, which is better than your current mapping probably 10 years out of date. I don't think you can upgrade an old system with the latest mapping because technology has moved on a long way since the sat nav was designed for your car. Buy a new TomTom or Garmin and forget about the car's system.

We use Advanced Security for Outlook from Mapilab for this. It is free, also for commercial use, and still keeps Outlook safe (by only allowing access from approved applications). Just apposed to previously mentioned solutions that cost either money, or may compromise security.

You can disable the security pop-up using Outlook's Trust Center. Check here.

I got a mail the other day from a colleague requesting assistance on behalf of a partner around an Office 365 certificate error in Outlook.
The scenario was that a certificate expired – I’m not sure what certificate they referred to so I assumed the ADFS/TLS certificate. They renewed the certificate, but Outlook clients were still popping up with a certificate validation error.
The first thing you need to understand with this is that you don't manage the certificates for Exchange in Office 365 for your Outlook Anywhere connections. Microsoft manages this on the Office 365 backend. You will only manage your ADFS and TLS certificates from your side.
I did some checks on the domain and noticed that they have an A record pointing to the root domain that listens on 443 and 80 for their www site- like below:
This site had a web server certificate loaded which was expired (not the same certificate the guy was talking about initially).
So why is Outlook popping up with a certificate validation issue on from their website? Easy….
The Outlook Autodiscover process will first check the root domain for any Autodiscover service points – see here: http://technet.microsoft.com/en-us/library/cc539049.aspx
Outlook will also run Autodiscover during startup, refreshes as often as the TTL period specifies, usually 1 hour and then also during network connectivity issues to a server.
Essentially the request will see that the root domain record is listening on 443, but the certificate is expired. This results in Certificate validation errors on the first step when Outlook goes through the Autodiscover process.
There are two ways to resolve this:
- Remove the root domain record to the site and just use the www record. I don’t like root domain records like this, just because of this – it has potential to impact other services dependent on lookups.
- Renew the certificate on the site – the Autodiscover process will then fail and then move on to the next step of the process.
Happy Office 365’ing!!!
