I have several devices (smartphone, tablet) syncronized with outlook.com calendar, but on my PC I use Thunderbird as main tool for managing multiple email accounts. I do not know how to syncronize the calendar in Thunderbird with the calendar in outlook.com. Thanks for suggestions or advices.

Thanks. I tried but at the end of the process it gives the following error message:

Error during checking of server and mailbox: HTTP Server error 503: Service unavailable URL:https://outlook.com/ews/exchange.asmx

(Code: -19)

Thanks again in any case. If you or someone else have other suggestions, please let me know.

Did you click the link in the middle of my article and enter your username and password to see the creation of a service page. The error you are getting leads me to think you did not.

Yes I clicked the link and entered username and password but, with the last step of the article, it gives always the same error message.
