Если под контролем вы подразумеваете api, то уже есть один - Exchange Web Services (EWS). Предполагая, что вы имеете дело с обменом, и настроили EWS. Веб-сервисы обычно располагаются по адресу:
https://[yourmaildomain.com]/EWS/Exchange.asmx
Вот небольшой код - не протестирован (также на vb.net)
Dim esb As New ExchangeServiceBinding()
esb.Credentials = New NetworkCredential("someusername", "somepassword")
esb.Url = "https://[yourmaildomain.com]/EWS/Exchange.asmx"
Dim addressType As New EmailAddressType()
With addressType
.EmailAddress = "email@domain.com"
.MailboxType = MailboxTypeType.Mailbox
.MailboxTypeSpecified = True
End With
' properties
Dim itemProperties As New ItemResponseShapeType()
itemProperties.BaseShape = DefaultShapeNamesType.AllProperties
' Identify which folders to search to find items.
Dim folderIDs(0) As DistinguishedFolderIdType
folderIDs(0) = New DistinguishedFolderIdType()
folderIDs(0).Id = DistinguishedFolderIdNameType.contacts
folderIDs(0).Mailbox = addressType
Dim findItemRequest As New FindItemType()
findItemRequest.Traversal = ItemQueryTraversalType.Shallow
findItemRequest.ItemShape = itemProperties
findItemRequest.ParentFolderIds = folderIDs
' send request
Dim findItemResponse As FindItemResponseType = esb.FindItem(findItemRequest)
Dim rmta As ResponseMessageType() = findItemResponse.ResponseMessages.Items
For Each rmt As ResponseMessageType In rmta
If rmt.ResponseClass = ResponseClassType.Success Then
Dim firmt As FindItemResponseMessageType = CType(rmt, FindItemResponseMessageType)
If firmt IsNot Nothing Then
Dim root As FindItemParentType = firmt.RootFolder
Dim obj As Object = root.Item
If TypeOf obj Is ArrayOfRealItemsType Then
Dim items As ArrayOfRealItemsType = DirectCast(obj, ArrayOfRealItemsType)
If items.Items IsNot Nothing Then
For Each it As ItemType In items.Items
If TypeOf it Is ContactItemType Then
Dim cit As ContactItemType = DirectCast(it, ContactItemType)
Response.Write("<p>")
Response.Write(cit.Subject)
Response.Write("<p>")
