interval value of 30 minutes, the availability value with the higher digit value is assigned to the
whole interval period. For example, if a user has a 25 minutes of free time (value 0) followed by 5
minutes of busy time (value 2), the 30 minute interval is assigned a value of 2 in the server
response.
The server determines the number of digits to include in the MergedFreeBusy element by dividing
the time interval specified by the StartTime element (section 2.2.3.151.1) value and the EndTime
element (section 2.2.3.55.1) value by 30 minutes, and rounding the result up to the next integer.
The MergedFreeBusy element value string is populated from the StartTime element value
onwards, therefore the last digit represents between a millisecond and 30 minutes. A query for data
from 13:00:00 to 13:30:00 returns a single digit but a query from 12:59:59 to 13:30:00 or
13:00:00 to 13:30:01 returns two digits.
Any appointment that ends inside a second of the interval requested shall impact the digit
representing that timeframe. For example, given a calendar that contains a 5 minute OOF
appointment from 12:00 to 12:05, and is free the rest of the day, queries would result in the
following:
•If a query is made for 12:00:00 to 13:00:00, the result is "30", where each digit represents
exactly 30 minutes.
•If a query is made for 12:04:59 to 13:00:00, the result is "30", where the "0" maps to 12:34:59
to 13:00:00.
•If a query is made for 12:05:00 to 13:00:00, the result is "00" where the second 0 maps the last
25 minutes of the interval.
The client MUST consider daylight saving time transitions and might need to add or remove time
intervals from the MergedFreeBusy element value string, as there are days that have more or less
than 24 hours.
If the Availability element is included in the response, the response MUST also include the Status
element (section 2.2.3.152.11). The MergedFreeBusy element is also included if the Status
element value indicates success.
2.2.3.92 Message
The Message element is an optional child element of the Error element in Autodiscover command
responses that contains the error string localized using the Culture (section 2.2.3.36) value
specified in the Response element, enabling the client to display error status to the end-user.
