The certificate error that pops up shows you that it is finding the certificate on your company’s public website. Why the error and why is it showing the company’s public website’s certificate.
Well first, let’s explore a little on the steps External Autodiscover goes through in order to find Exchange.
When expressed as a file, the i Calendar data will typically have an "ics" extension, but really it is just text.It also has a MIME type of "text/calendar" For our scenario, we'll assume we have a website with events on it.The user clicks the Save & Close and it now appears on their calendar.We're not just limited to do this from a webpage either.We could just as easily save the to a file and Process.
Start it to open it for the user if we're in a Windows app.
I have a blog post on Outlook Certificate Errors which applies to Outlook 2007, Outlook 2010, and Outlook 2013. That blog post describes an incorrect certificate on Exchange itself.
For example, you make a connection to Exchange and your Internal URLs, External URLs, and Autodiscover Service Internal URI FQDN is not defined on the certificate.
We can create the same with the following code: What happens now when the user clicks our link?
They'll get prompted just as before, but when they click OK to add it, it will add the i Calendar feed as a second calendar in their calendar application.
For any of these events, we want to allow the user to be able to selectively add an event to their own local calendar. I want to write it once and then forget it ever existed.
