When a user in Outlook queries for the free and busy information
of a user on a partner system, Calendar Connector intercepts the
query and checks records in the free busy public folder in
Microsoft Web Storage System on the Exchange server to see when the
requested free and busy record was updated. Calendar Connector will
perform one of the following actions:
If the record was updated within the time specified by the
Maximum age in minutes setting, then Calendar Connector
returns the available data without querying the partner system. The
Maximum age in minutes setting is configured on the Calendar
Connector's General tab, and its default is 15 minutes.
If the free and busy data in Web Storage System has not been
updated in the specified amount of time, then a request for current
free and busy data is sent to the free and busy information store
on the partner system.
If a query is sent to the partner system for more current
information, then Calendar Connector waits for the amount of time
that you specified on the connector's General tab, in the
Maximum number of seconds to wait for a response field.
Then, one of the following actions will occur:
If the partner system responds before the specified amount of
time elapses, then the updated data is written to the free and busy
record in Exchange and is returned to the client requesting the
free and busy data.
If the partner system does not respond within the time allowed,
or if Calendar Connector does not respond to the partner system to
get updated data, Exchange sends the old data in the free and busy
record to the client.
If the partner system responds after the time allowed, the data
is still written to the free and busy public folder but is not
returned to the Exchange client who originally requested the
Note Exchange, and users on
partner systems, will not be notified that free and busy
information may be old, or that more up-to-date information could
be obtained. In addition, users will not receive notification if
the Calendar Connector service has been stopped.
