Exchange Scanner


The Microsoft Exchange Scanner is a new adapter available since migration-center 3.2.6. The Exchange scanner can extract messages (emails) from Exchange mailboxes and use it as input into migration-center, from where it can be processed and migrated to other systems supported by the various mc importers.
The Microsoft Exchange Scanner currently supports Microsoft Exchange 2010. It uses the Independentsoft JWebServices for Exchange Java API to access an Exchange mailbox and extract emails including attachments and properties.
Scanner is the term used in migration-center for an input adapter. Using the Exchange Scanner Module to read the data that needs processing into migration-center is the first step in a migration project, thus scan also refers to the process used to input data to migration-center.
The scanner module works as a job that can be run at any time and can even be executed repeatedly. For every run a detailed history and log file are created.
A Scanner is defined by a unique name, a set of configuration parameters and an optional description.
Exchange Scanners can be created, configured, started and monitored through migration-center Client, but the corresponding processes are executed by migration-center Job Server.

Exporting objects from an Exchange mailbox

The Exchange scanner connects to the Exchange Server with a specified Exchange mail account and can extract messages from one (or multiple) folder(s) within the current user’s or other user’s mailboxes. The account used to connect to exchange must have delegate access permission to the other accounts from which mails will be scanned. All subfolders of the specified folder(s) will automatically be processed as well; an option for excluding select subfolders from scanning is also available. See chapter Exchange scanner parameters below for more information about the features and configuration parameters available in the Exchange scanner.
In addition to the emails themselves, attachments and properties of the respective messages are also extracted. The messages and included attachments are stored as .eml files on disk, while the properties are written to the mc database, as is the standard with all migration-center scanners.
After a scan has completed, the newly scanned email messages and their properties are available for further processing in migration-center.

Exchange Scanner Properties

To create a new Exchange Scanner job, specify the respective adapter type in the Scanner Properties window – from the list of available adapters, “Exchange” must be selected. Once the adapter type has been selected, the Parameters list will be populated with the parameters specific to the selected adapter type, in this case the Exchange adapter’s parameters.
The Properties window of a scanner can be accessed by double-clicking a scanner in the list, or selecting the Properties button or entry from the toolbar or context menu.

Common scanner parameters

Configuration parameters
Enter a unique name for this scanner
Adapter type
Select the “Exchange” adapter from the list of available adapters
Select the Job Server location where this job should be run. Job Servers are defined in the Jobserver window. If no Job Server migration-center will prompt the user to define a Job Server Location when saving the Importer.
Enter a description for this job (optional)

Exchange scanner parameters

Configuration parameters
The username that will be used to connect to the Exchange server. This user should have delegate access to all accounts that will be scanned.
The password that will be used to connect to the exchange server.
The domain against the user will be authenticated. It should be left empty for authentication against exchange server domain.
Specify if the connection between Job Server and Exchange server will be established over a secure SSL channel.
The host name or IP address of the exchange server.
Exchange folder paths to scan.
The syntax is \\<accountname>[\folder path] or \folderPath. If only the account is given (ex: \\[email protected]) then the scan location will be considered to be the "Top of Information Store" folder of the user. If no account is specified, the path is considered to be in the account specified in the “username” property. Multiple paths can be entered by separating them with the “|” character.
  • \\user\Inbox would scan the Inbox of user (including subfolders)
  • \Inbox\sales is equivalent to \\“username”\Inbox\sales
Exchange folder paths to exclude from scanning. Follows the same syntax as scanFolderPaths above.
Example: \\user\Inbox\Personal would exclude user’s personal mails stored in the Personal subfolder of the Inbox if used in conjunction with the above example for scanFolderPaths.
A comma separated list of Exchange properties to be ignored by the scanner.
At least Body,HTMLBody,RTFBody,PermissionTemplateGuid should be always excluded as these significantly increase the size of the information retrieved from Exchange but don’t provide any information useful for migration purposes in return.
Folder path. The location where the exported object content should be temporary saved. It can be a local folder on the same machine with the Job Server or a shared folder on the network. This folder must exist prior to launching the scanner and must have write permissions. migration-center will not create this folder automatically. If the folder cannot be found an appropriate error will be raised and logged. This path must be accessible by both scanner and importer so if they are running on different machines, it should be a shared network folder.
Boolean - If true, the mails will be exported as .msg files, otherwise they will be exported as .eml files.
Number - The number of concurrent threads that will be used for scanning the emails from the configured locations.
Sets the verbosity of the log file.
Possible values:
1 - logs only errors during scan
2 - is the default value reporting all warnings and errors
3 - logs all successfully performed operations in addition to any warnings or errors
4 – logs all events (for debugging only, use only if instructed by fme product support since it generates a very large amount of output. Do not use in production)
Note: Configuration parameters ending with (*) are mandatory.

Log files

A complete history is available for any Exchange Scanner job from the respective items’ History window. It is accessible through the History button/menu entry on the toolbar/context menu. The History window displays a list of all runs for the selected job together with additional information, such as the number of processed objects, the start and ending time and the status.
Double clicking an entry or clicking the Open button on the toolbar opens the log file created by that run. The log file contains more information about the run of the selected job:
  • Version information of the migration-center Server Components the job was run with
  • The parameters the job was run with
  • Execution Summary that contains the total number of objects processed, the number of documents and folders scanned or imported, the count of warnings and errors that occurred during runtime.
Log files generated by the Exchange Adapter can be found in the Server Components installation folder of the machine where the job was run, e.g. …\fme AG\migration-center Server Components <Version>\logs
The amount of information written to the log files depends on the setting specified in the ‘loggingLevel’ start parameter for the respective job.
