How to Create URL (Web Parts) for Outlook Web App with Recipient and Subject

Many companies are considering, for economic reasons, the disposal of MS Office, and MS Outlook too, while having Microsoft Exchange as e-mail system. In these scenarios, the use of Outlook Web App replaces the use of MS Outlook as the email client. When you use Outlook Web App instead of MS Outlook, you can come across the problem of the links (URL), sometimes present in web pages, which contain the mailto parameter. The problem that occurs is that you can not open Outlook Web App, clicking on the links with the mailto parameter. If the web page that contains links with the mailto parameter is part of the company’s Intranet, then you can replace the links that contain the parameter mailto, with links that point to Outlook Web App.

Outlook Web App provides a set of parameters to create the URL, to be inserted into web pages, in which you can specify the recipients or the subject of the message:

• URL with one recipient and the subject of the message: 

href="https://<FQDN_Exchange_Server>/owa/?ae=Item&a=New&t=IPM.Note&to=alessandro.tani@homeworks.it&subject=Enter the subject of your message"

• URL with a list of recipients: 

href="https://<FQDN_Exchange_Server>/owa/?ae=Item&a=New&t=IPM.Note&email=mailto:alessandro.tani%40homeworks.it,
mario.rossi%40homeworks.it,giuseppe.verdi%40homeworks.it,
cristoforo.colombo%40homeworks.it"

Then, within a web page you can enter the following links:

• Link with one recipient and the subject of the message:

<a href="https://<FQDN_Exchange_Server>/owa/?ae=Item&a=New&t=IPM.Note&to=alessandro.tani@homeworks.it&subject=Enter the subject of your message">alessandro.tani@homeworks.it</a>

• Link with a list of recipients:

<a href="https://<FQDN_Exchange_Server>/owa/?ae=Item&a=New&t=IPM.Note&email=mailto:alessandro.tani%40homeworks.it,
mario.rossi%40homeworks.it,giuseppe.verdi%40homeworks.it,
cristoforo.colombo%40homeworks.it">alessandro.tani@homeworks.it,
mario.rossi@homeworks.it,giuseppe.verdi@homeworks.it,
cristoforo.colombo@homeworks.it</a>

In this way you can avoid the problem of web page with mailto links, which are not correctly interpreted by Outlook Web App.
