Outlook and Exchange Active Sync on mobile device uses Autodiscover for configuring and maintaining server settings for client that is configured to access a Mailbox. On the Initial configuration, we know Outlook will do an Auto Discovery look up to configure the outlook profile. Once the outlook profile configured, it will do an Auto Discovery look up to see if any changes on the Url’s or changes on the mailbox settings.
We need to know when outlook will do an Auto Discovery look up. Outlook clients automatically connect to the Autodiscover service in the following conditions:
- When outlook client starts, both opening for the first time and every time it starts
- Every 60 minutes once
- Any time that the client’s connection to an Exchange Server fails
