According to link above, we can caching the information for Autodiscover.

The question is:

1) Should i serialize ExchangeService object to xml or just cache some of the properties (which properties) ? (I want to improve performance of the system because autodiscoverurl is too slow)

Answer 1

I would suggest you cache the minimum information your app needs to function.

This page suggests

• Autodiscover endpoint
• EWS URL and any other settings retrieved from the Autodiscover response

Answer 2

Most apps just cache the EWS URL. If you are requesting any additional properties when making GetUserSettings operation (SOAP) , you could cache them as well. And please make AutoDiscover request at least once every 24 hours. I am not sure it would help to serialize ExchangeService, or if it is even possible to serialize this.
