Unique ID Registry Values

Note: You must set UpdateConfig to 1 for changes to the following registry settings to take effect.

HashOrder

Type: REG_SZ

Data: This value is only for emails that have not been through the envelope journaling process. It specifies a comma-separated list of MAPI properties used by the Universal Adapter to generate a unique ID for each email processed. For normal use, we recommend you use:

InternetMessageID, ClientSubmitTime

Some archive solutions (for example, ZANTAZ Digital Safe Adapter) replace the InternetMessageID property on each email. This makes the property unreliable for detecting duplicate messages amongst emails processed by other archive solutions.

In this situation, we recommend you use a combination of the following MAPI properties to generate the unique ID:

SubjectID, SenderNameID, DisplayToID, PlainTextBody, ClientSubmitTime

Note: Using the PlainTextBody property is an optional recommendation as it can potentially have an impact on processing time.

EnvelopeInnerOrder

Type: REG_SZ

Data: This value is only for emails that have been through the envelope journaling process. It specifies the MAPI properties the Universal Adapter uses to generate a unique ID from the inner part of such an e‑mail (that is, the part that contains the original e‑mail). For example:

ClientSubmitTime

EnvelopeOuterOrder

Type: REG_SZ

Data: This value is only for emails that have been through the envelope journaling process. It specifies the MAPI properties the Universal Adapter uses to generate a unique ID from the outer part of such an e‑mail (that is, the journal report containing the transport envelope data of the original email). For example:

PlainTextBody
