The information below expands on some of the concepts outlined in the Legacy Archive Data Management guide, and provides strategies to complete your Ingestion process more efficiently.

 

De-duplication

Duplicates within any data being ingested at any time, within the one process or across multiple processes at different times, will be deduplicated (if containing the same message ID and sent date). However, if an item is already archived via journaling or external email flow through Mimecast, another copy being ingested will duplicate within the archive causing two copies to exist in the archive.

Provided PU data typically contains duplicate copies across multiple PU PST files and EML folders of messages with multiple internal recipients.  This is because the same message is exported to, or is located in each user’s own PU PST.

 

 

PST Folder Paths

Folder paths of all messages extracted from PU PSTs only are recorded by default. This information is then imported into each user’s Mimecast account for customers that have subscribed to the Folder Sync feature. Alternatively, this information is retained and can be applied in the future if the feature is subsequently purchased. Contact your Account Manager if you wish to subscribe to this service, as the recorded information can be simply imported once subscribed to.

imported and MSE synced items will be displayed in the same folder structure exactly as they were in the provided PSTs and mailbox root respectively. The root of the mailbox and the imported PST is mapped to the Exchange Folders. This includes folders located directly under the PST root, Deleted Items, Drafts, Tasks, Calendar Folders, etc.

 

  • Imported messages and folders cannot be moved directly within Mimecast Exchange Folders, however MSE Folder Sync will display the new location of any that are moved within the user’s live mailbox.
  • Folder paths of messages are not recorded from NPU PSTs or any EMLs provided.
Examples
Provided within PST for import:

{PST1 Root}\subfolder 1\Message 6

{PST2 Root}\inbox\subfolder 1\Message 1

{PST3 Root}\inbox\subfolder 2\subfolder 3\Message3

MSE synced:

{Mailbox Root}\subfolder 1\Message 5

{Mailbox Root}\inbox\subfolder 1\Message 2

{Mailbox Root}\inbox\subfolder1\subfolder3\Message4

Displayed in Mimecast Exchange folders within Mimecast for Outlook and Mimecast Personal Portal:

{Exchange folders root}\subfolder 1\Message 5

                                                   Message 6

{Exchange folders root}\inbox\subfolder 1\Message 1

                                                            Message 2

{Exchange folders root}\inbox\subfolder 2\subfolder 3\Message 3

                                                                             Message 4

 

To view a message in its folder, ensure Full Folder View within Mimecast Personal Portal is activated.

 

Mimecast Synchronization Engine (MSE) Folder Sync service records the path of the folder containing a message within the users Exchange mailbox only, and displays it under Exchange Folders within Mimecast for Outlook and Mimecast Personal Portal where imported items are also displayed.

 

Once Full Folder View is activated in Mimecast Personal Portal, the following items will now be displayed in their folders:

 

  • Standard messages that were provided in PU PSTs which were imported
  • Standard messages archived since Mimecast has been processing all your emails and the Folder Sync component of MSE has been recording their folder information from within the mailbox. This includes any items subsequently deleted.
