ConvertId Operation

Topic Last Modified: 2008-06-11

The ConvertId operation, introduced in Microsoft Exchange Server 2007 Service Pack 1 (SP1), converts item and folder identifiers between formats that are accepted by Exchange 2007.

Important

The Exchange Web Services identifier format is different in the initial release version of Exchange 2007 and Exchange 2007 SP1.

You can convert the following identifiers by using this operation:

  • The identifier format for Exchange Web Services in the initial release version of Exchange 2007. This is represented by the EwsLegacyId enumeration value in the IdFormatType.
  • The identifier format for Exchange Web Services in Exchange 2007 SP1. This is represented by the EwsId enumeration value in the IdFormatType.
  • The MAPI identifier, as in the PR_ENTRYID property. This is represented by the EntryId enumeration value in the IdFormatType.
  • The availability calendar event identifier. This is a hexadecimal-encoded representation of the PR_ENTRYID property. This is represented by the HexEntryId enumeration value in the IdFormatType.
  • The Exchange store identifier. This is represented by the StoreId enumeration value in the IdFormatType.
  • The Microsoft Office Outlook Web Access identifier. This is represented by the OwaId enumeration value in the IdFormatType. The passing of URLs that are created from this identifier to Outlook Web Access is not supported.

Note

The ConvertId operation validates that a given SMTP address has a valid format. The operation does not determine whether an SMTP address represents a valid mailbox.

ConvertId Request Example

Description

The following example of a ConvertId request shows how to convert from an Exchange Web Services identifier to an Outlook Web Access identifier.

Code

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="https://schemas.xmlsoap.org/soap/envelope/"
               xmlns:t="https://schemas.microsoft.com/exchange/services/2006/types">
  <soap:Header>
    <t:RequestServerVersion Version="Exchange2007_SP1"/>
  </soap:Header>
  <soap:Body>
    <ConvertId xmlns="https://schemas.microsoft.com/exchange/services/2006/messages"
               xmlns:t="https://schemas.microsoft.com/exchange/services/2006/types"
               DestinationFormat="OwaId">
      <SourceIds>
        <t:AlternateId Format="EwsId" Id="AAMkAGZhN2IxYTA0LWNiNzItN="
                       Mailbox="user1@example.com"/>
      </SourceIds>
    </ConvertId>
  </soap:Body>
</soap:Envelope>

Comments

The RequestServerVersion element in the SOAP header must be set to Exchange 2007 SP1 for this operation to work. The item identifier has been shortened to preserve readability.
