WebDev 18 and Exchange

Startbeitrag von Alan Evans am 25.09.2013 11:47


I was wondering if anyone could point me in the right direction? I've recently acquired WebDev18 and am building an website that will be accessed through Android tablets. I've a requirement to be able to connect to a Microsoft Exchange server which is running on the same network as the WebDev server. However, I'm not sure how to go about accessing the Exchange server via WebDev. I've got the EmailStartOutlookSession command working fine and bringing back emails and appointments, but this is running on my laptop, in developer mode from the WebDev GUI and using my Microsoft Outlook program on the laptop as a conduit.

My question is, how do I set up the Outlook client on the Server? If I have multiple users accessing the WebDev site, how can one Outlook client work? Each user will of course have their own Exchange profiles. If I use EWS....well, that's it, how WOULD I use EWS from WebDev?

Many thanks for any help,



Hi Alan

The level of integration you are describing can be achieved IMHO only via OLE automation (and maybe only using redemption)....

However, Microsoft itself is telling the whole word that OLE automation has NOTHING TO DO on a web server, for multiple reason (google search will give you the gritty details)...

So my take on your todo would be:
- on your web site, write in a OutlookTodo file whatever is needed with all the details (user, task, etc)
- on a SEPARATE server, create a WINDEV executable that will read the todo task, do it using OLE automation or redemption, then write the result in the same file
- from your webdev site, check either regularly, from a timer in the browser side, if the task has been done and display the result, or let the user come back and see the results later

If you have a high volume, set several instances of the EXE on your separate server (or even on several separate servers)

Best regards

Hi Alan,

As every backend platform is webservices enabled to do almost any basic operation, that goes for MS Exchange as well.

So I would look at integrating via Exchnage webservices:

Just my 2 cents,

Thanks to you both for your input.


I would like to be able to use the EWS, but it's how to do it from WebDev? How would I be able to see the exposed methods for the EWS, certainly trying to do this from a WebServices import in WebDev doesn't work, I get the message that no Web Services were found, although of course if I do this from a browser manually I get see the services.


I think I'm going to have to do it the way you mention, at least whilst the main audience is Android tablets. Long winded, but will work!
