Lync Connector performs a synchronization between the Lync archiving database and Enterprise Vault.cloud on a scheduled basis, typically once an hour. You can also trigger a synchronization on demand, if one is not currently running.
In each synchronization Lync Connector extracts any unextracted Lync transcripts from the Lync archiving database in .eml email message format, and processes the extracted transcripts as follows:
It verifies the suitability of each transcript for archiving. Transcripts that are too large for forwarding to Enterprise Vault.cloud are immediately excluded and placed in the excluded subfolder of Lync Connector's working folder.
It substitutes the sender SIP address and the recipient SIP address in the transcript email with the corresponding primary email addresses. To determine the primary email address for each SIP address, Lync Connector performs an Active Directory lookup.
It wraps each transcript email message in an envelope that is addressed to the journal address that you have configured for Lync on-premises archiving.
It then forwards the email message to Enterprise Vault.cloud using SMTP, either directly through outgoing port 25, or else indirectly through an on-premises SMTP server that you have provided.
Lync Connector processes a maximum of 100,000 extracted transcripts in each synchronization. Any unprocessed transcripts are queued for processing in the next synchronization, ahead of any transcripts that are newly extracted.
The original extracted email of each successfully processed transcript is placed in the completed subfolder of the Lync Connector working folder, and retained for a configurable period.
If a transcript fails processing, or if none of its participants is recognized as having an archive account, the processing is automatically retried at regular intervals for an auto-retry period. The auto-retry period is 72 hours by default. If a transcript remains unsent at the end of the auto-retry period, it is placed in the failed or excluded subfolder of the working folder, respectively.
At the end of the synchronization Lync Connector performs some housekeeping operations, and generates its reports for the synchronization.
Lync Connector provides a mechanism for you to manually trigger the reprocessing of any transcript at the next synchronization.
