Connection
Mimecast API Endpoint: Enter the Mimecast endpoint to use for API requests.
Authentication Endpoint: Enter the Mimecast endpoint used to authenticate requests.
Select Credential: Choose the Mimecast Client ID and Secret from the dropdown.
For support setting up credentials use our guide on managing credentials.
Select the Domains tab.
Domains
Included Domains: Choose to crawl specific domains only. Enter the domain names you want to crawl using Regular Expression.
If blank, all domains will be crawled.
Include local domains: If checked, local domains will also be processed.
This depends on the filtered domains.

Messages
Start Date: Select the earliest date messages should be retrieved from when crawling a mailbox for the first time.
This also applies if Ignore Delta Tokens is checked.
Ignore delta tokens: Check this to ignore delta tokens and re-crawl all messages.
Use this to find missing messages, if the Start Date is changed, or to process deleted messages.
This is slower than a standard delta crawl.
Excluded Message Subjects: Limit the emails processed depending on their subject. Enter the subjects you don't want processed using regular expressions.
If blank, all messages will be processed.
Blank Subject Default: Enter a default subject for any messages processed without one.
Attachments

If blank, all attachments will be processed.
Blank Attachment Name: Enter a default name for any attachments processed without one.
Advanced
Parallelism
Parallel Mailbox Crawling: Enter the maximum number of mailboxes that should be crawled at once.
Parallel Folder Query: Enter the maximum number of Elastic queries that can be processed at once.
This may impact Elastic performance.
Parallel Mailbox Deletion: Enter the maximum number of mailboxes that can be deleted at once.
This may impact Elastic performance.
Logging
Trace Level: Select the connection trace level from the dropdown.
None - Do not log graph calls
Calls - Log URLs and status codes
All - Log URLs, status codes, request forms and JSON responses
Stats Logging Interval (Seconds): Choose how often the Graph API call stats are logged in seconds.

Performance
Results Page Size: Enter the maximum number of results retrieved in a single request.
Retry After Multiplier: Enter a multiplier to pause processing after receiving a 'retry after' message. The multiplier will be multiplied by the 'retry after' value.
Retry after values are typically between 1 and 3. A multiplier of 1000 will convert the value to that number of seconds.
Delta Token Offset (Minutes): Enter the number of minutes to overlap that is applied to a saved delta token.
This allows time zones to be accounted for.
Negative values are subtracted.
Authentication Token Offset (Seconds): Enter an offset in seconds that is applied to the authentication token expiry.
Negative values are subtracted.
