The Exchange Web Services Settings dialog is opened by clicking the Exchange Web Services Settings... button on the Options dialog:
When resetting the automatic replies senders list, Out-of-Office Extender connects using to Exchange Server via Exchange Web Services (EWS). In order to connect to EWS, it is necessary to determine the URL for EWS using a process called Autodiscover. This dialog is used to configure how the Autodiscover process works.
Note In normal conditions, the connection to EWS will be configured automatically using the Autodiscover mechanism built into Exchange Server. It should only be necessary to change these advanced settings if specific problems are being encountered that prevent Autodiscover from working correctly and/or performance problems are being encountered.
The following settings can be configured:
Setting |
Description |
|---|---|
Use the default autodiscover mechanism |
Specifies that the default autodiscover mechanism should be used; this is the normal setting; how this mechanism works can be fin tuned using the following options. |
Skip Service Connection Point (SCP) lookup |
Specifies that the autodiscover mechanism will not query Active Directory for Service Control Points (SCP). Only available when the default autodiscover mechanism is selected. |
Skip root domain query based on the primary SMTP address |
Specifies that the autodiscover mechanism will not query for an autodiscover service at a URL based on the root domain found in the primary SMTP email address for a user. The URL takes for the format https://<smtp-address-domain>/autodiscover/autodiscover.xml, so for a user with the email address [email protected], this would resolve to https://contoso.com/autodiscover/autodiscover.xml. Only available when the default autodiscover mechanism is selected. |
Skip query for the Autodiscover domain in the root domain |
Specifies that the autodiscover mechanism will not query for a service at a URL based on the autodiscover sub-domain of the root domain found in the primary SMTP email address for a user. The URL takes for the format https://autodiscover.<smtp-address-domain>/autodiscover/autodiscover.xml, so for a user with the email address [email protected], this would resolve to https://autodiscover.contoso.com/autodiscover/autodiscover.xml. Only available when the default autodiscover mechanism is selected. |
Skip the HTTP redirect method |
Specifies that the autodiscover mechanism will not query for an HTTP redirect on the autodiscover sub-domain of the root domain found in the primary SMTP email address for a user. The URL takes for the format https://autodiscover.<smtp-address-domain>/autodiscover/autodiscover.xml, so for a user with the email address [email protected], this redirect query would be made against https://autodiscover.contoso.com/autodiscover/autodiscover.xml. Only available when the default autodiscover mechanism is selected. |
Use the following autodiscover URL |
Specifies that the autodiscover mechanism should use the specified fixed URL, instead of querying Active Directory for the Service Connection Points. |
Use the following Exchange Web Services URL |
This setting disables the autodiscover mechanism and forces the connection to Exchange Web Services to use the specified fixed URL. |
Use the first good Exchange Web Services URL found |
When the default autodiscover mechanism is being used, this setting stipulates that once the first good EWS URL has been discovered (from an SCP), the mechanism should stop and use that URL alone (rather than continuing and querying further SCPs). This can be useful if you have a number of autodiscover servers (i.e. a number of SCPs), some of which are not currently available. |
Query Outlook provider settings first |
When using the autodiscover mechanism, each autodiscover service (i.e. each SCP) is queried using the standard autodiscover protocol. If this fails, the service is queried for the settings to be used by Outlook (which uses a different protocol). In some environments, the standard autodiscover protocol is not available on any server, so it is beneficial (from a performance standpoint) to query for the Outlook Provider settings first. |
When the settings have been configured as required, click the OK button save your changes and close the dialog. Alternatively, click the Cancel button to close the dialog without saving any changes.
