Account Logs

 

Account Audit and Search Audit event logs cannot be migrated to your new Mimecast Australia account. Your existing Mimecast account will still be accessible for 90 days after your migration.

 

Archive

 

Your archive data will be migrated from your existing account to your new account, however the following specific items cannot be migrated.

 

  • Archive Search History
  • Archive Saved Searches
  • Archive eDiscovery Cases
  • Archive Smart Tags

 

You will be able to created these manually in your new Mimecast Australia account. Mimecast support staff are unable to migrate these on your behalf because they need to be created by an Administrator with content access to your organization's archive.

 

Attachment Link on Size

 

Links to attachments that were subject to an Attachment Link on Size policy will expire 90 days after your migration has been signed off when your existing Mimecast account is disabled. Consequently these attachments will not be accessible using the link in the message in the user's Exchange mailbox or by any external recipients of such a message. If your organization archives with Mimecast your internal users will be able to access the original attachment in the archive using Mimecast applications.
