Get singleValueLegacyExtendedProperty

Namespace: microsoft.graph

You can get a single resource instance expanded with a specific extended property, or a collection of resource instances that include extended properties matching a filter.

Using the query parameter $expand allows you to get the specified resource instance expanded with a specific extended property. Use a $filter and eq operator on the id property to specify the extended property. This is currently the only way to get the singleValueLegacyExtendedProperty object that represents an extended property.

To get resource instances that have certain extended properties, use the $filter query parameter and apply an eq operator on the id property. In addition, for numeric extended properties, apply one of the following operators on the value property: eq, ne,ge, gt, le, or lt. For string-typed extended properties, apply a contains, startswith, eq, or ne operator on value.

The filter is applied to all instances of the resource in the signed-in user's mailbox.

Filtering the string name (Name) in the id of an extended property is case-sensitive. Filtering the value property of an extended property is case-insensitive.

The following user resources are supported:

• calendar
• contact
• contactFolder
• event
• mailFolder
• message

As well as the following group resources:

• group calendar
• group event
• group post

See Extended properties overview for more information about when to use open extensions or extended properties, and how to specify extended properties.

Request 2

The second example gets messages that have the string-typed single-value extended property specified in the filter. The filter looks for the extended property that has:

• Its id equal to the string String {66f5a359-4659-4830-9070-00047ec6ac6e} Name Color (with URL encoding removed here for ease of reading).

• Its value equal to the string Green.

Response 2

A successful response is indicated by an HTTP 200 OK response code, and the response body includes all the properties of the messages that have the extended property matching the filter. The response body is similar to the response from getting a message collection. The response does not include the matching extended property.

Request 3

The third example gets messages that have the string-typed single-value extended property specified in the filter. The filter looks for the extended property that has:

• Its id equal to the string String {66f5a359-4659-4830-9070-00047ec6ac6e} Name Color (with URL encoding removed here for ease of reading).

• Its value containing the string green.

Response 3

A successful response is indicated by an HTTP 200 OK response code, and the response body includes all the properties of the messages that have the extended property matching the filter. For example, a message that has a single-value extended property with the id equal to the string String {66f5a359-4659-4830-9070-00047ec6ac6e} Name Color, and the value Light green, would match the filter and be included in the response.

The response body is similar to the response from getting a message collection. The response does not include the matching extended property.

Request 4

The next 2 examples show how to get messages that have non-string typed single-value extended properties. For ease of reading, they do not include the necessary URL encoding.

The following example shows a filter that looks for the extended property that has:

• Its id matching the string CLSID {00062008-0000-0000-C000-000000000046} Name ConnectorSenderGuid.

• Its value being the GUID b9cf8971-7d55-4b73-9ffa-a584611b600b. To compare the property value with a GUID, cast ep/value to Edm.Guid.

GET https://graph.microsoft.com/v1.0/me/messages?$filter=singleValueExtendedProperties/any(ep:ep/id eq 'CLSID {00062008-0000-0000-C000-000000000046} Name ConnectorSenderGuid' and cast(ep/value, Edm.Guid) eq (b9cf8971-7d55-4b73-9ffa-a584611b600b))

The next example shows a filter that looks for the extended property that has:

• Its id matching the string Integer {66f5a359-4659-4830-9070-00047ec6ac6e} Name Pallete.

• Its value equal to the integer 12. To compare the property value with an integer, cast ep/value to Edm.Int32.

GET https://graph.microsoft.com/v1.0/me/messages?$filter=singleValueExtendedProperties/any(ep:ep/id eq 'Integer {66f5a359-4659-4830-9070-00047ec6ac6e} Name Pallete' and cast(ep/value, Edm.Int32) eq 12)

Response 4

For each of the preceding 2 examples, a successful response is indicated by an HTTP 200 OK response code, and the response body includes all the properties of the messages that have the extended property matching the corresponding filter. The response body is similar to the response from getting a message collection. The response does not include the matching extended property.
