Converting archival formats

Aid4Mail Enterprise is unique because it can read the files delivered by three major email archiving solutions: Google Vault, Mimecast and Proofpoint. Aid4Mail can access these archives in their native format, which spares you from the time-consuming process of unzipping their contents. You can migrate your archives to live accounts, like Exchange, Microsoft 365 (formerly Office 365) or Google Workspace (formerly G Suite), or to PST files for easy local access, or to non-proprietary formats like mbox or EML files.

If remote journaling was used in sending mail to Mimecast or Proofpoint, each archived email will be “wrapped” in a journaling envelope. Aid4Mail provides an option to conveniently remove this envelope during conversion to your target format.

Google Vault

Google offers several export formats for Google Vault emails. Aid4Mail currently supports the mbox format based on the “classic system”. Google’s PST format is not recommended as it lacks important metadata like Gmail labels and message status information.

If you choose to migrate your Google Vault archives to a live Gmail account, Aid4Mail will preserve all metadata—including assigned labels. If you export to Microsoft 365, an Exchange or IMAP account, or a local file format like PST, mbox or EML, you can fully restore the corresponding Gmail folder structure.

In our tests, Aid4Mail was able to convert a 10 GB Google Vault file to EML in just under 20 minutes. The resulting target location had 54 folders (matching the Gmail source folder structure), 1,014,208 emails totalling 38 GB of data.

Mimecast and Proofpoint

Mimecast offers access to its archive exports in two ways:

  1. Delivered by FTP as a collection of ZIP files. Emails are organized by date range and user accounts are mixed together.
  2. Delivered on an external hard drive. User accounts are organized under separate folders, each of which contains ZIP files with emails grouped by date range.

Proofpoint lets you export archive data through a search query in your browser. This creates a password-protected ZIP file with up to 100,000 messages in EML format.

As mentioned earlier, Aid4Mail can access these archives in their native format. With Proofpoint you will need to enter the correct ZIP password so that Aid4Mail can extract the EML files stored in them.

Depending on the size of your email archives, you may end up with terabytes of data and a very large number of ZIP files. In this case, you can speed up conversion by configuring Aid4Mail to process your Mimecast ZIP files concurrently. Processing will then proceed unattended until all your data is converted.

In some cases, email archives are only grouped by date range and not by account holder. In other words, emails belonging to different end-user accounts are mixed together. Thanks to its sophisticated template-based folder naming feature, Aid4Mail can reorganize your mail based on the account’s email address. The end result is a folder for each account holder, and all its owners' emails grouped together under it.

A client had a Proofpoint archive containing 3,284,983 emails totaling 985 GB. He used Aid4Mail to extract and reorganize the EML files by account holder. The whole process was completed by Aid4Mail in just 7 hours and 26 minutes. That's a rate of 122.7 emails per second!


Email migrations

Aid4Mail Enterprise is ideal for small to large-scale email migrations. It provides access to all the popular email service providers like Microsoft 365, Google Workspace, and Amazon WorkMail, as well as company servers running Microsoft Exchange, Dovecot, Courier, Zimbra, etc. Depending on the mail server, you can also access public and shared folders as well as use delegate access.

The Enterprise license allows you to install Aid4Mail on a server, networked computer, shareable USB flash-drive or in a virtual environment. These varied options should provide enough flexibility to execute your migration in an optimal manner. You can also choose between running the Aid4Mail GUI or the CLI console. Both let you run multiple migration jobs concurrently. The GUI is easier to use but may take some time to configure whereas the CLI can be fully automated through well-crafted batch scripts.

If you are migrating your accounts to Microsoft 365, you may consider converting them with Aid4Mail to PST files. Then use the Import service in the Microsoft 365 compliance center to quickly bulk-import your PST files to Exchange Online mailboxes in your organization. See the Learn about importing your organization’s PST files page for more information.

Aid4Mail is optimized for speed and is consistently faster than competing solutions. We recently ran a test on a 7-year old desktop PC with an Intel Core i7-5930K and an SSD drive. Aid4Mail converted 98,051 emails (9.97 GB) from Thunderbird to PST in just 12 minutes and 34 seconds. That’s 130 emails per second! Expect even faster conversions on the latest generation of high-end computers.

An on-premises solution like Aid4Mail is faster and more secure than a cloud-based solution. Here’s why:

  • Data security: Your data is going from your own servers and computers, directly to your chosen email provider. There are no third-party servers in undefined locations to compromise the security of your sensitive data.
  • Faster conversion: With Aid4Mail, the mail conversion is done on-premises and then uploaded. With cloud vendors, your mail is first uploaded to their servers, converted and only then sent to your new email provider. You save a whole step with Aid4Mail.
  • Complete control: Know exactly what is happening with your migration every step of the way. Mitigate any issues as they arise, instead of after all your mail has already been migrated.

Automation and integration

Aid4Mail Enterprise provides two consoles with a command-line interface (CLI). One is 32-bit and the other 64-bit. This enables you to match the bitness of your Outlook or Python installation if necessary.

The console allows you to seamlessly integrate the Aid4Mail processing engine directly into your workflow. Use it in scripts, batch files, or your own application to automate email processing. Or create a simplified user interface for your end users to control the features you want to expose to them.

Flexible licensing options

The Enterprise license is a cost-effective solution for teams and offers multiple installation options. You may share a single license with multiple users or use it as a portable solution in the field.

Aid4Mail licenses allow you to process an unlimited number of mail accounts and files, whether in-house or external. You can purchase a one-year license, or three years at a reduced price. During the license validity period, you benefit from free software updates and our legendary customer support.

On purchasing a license, you will receive an activation code that gets you up and running within minutes of making your payment. If you need to run Aid4Mail on a computer that doesn’t allow Internet access, simply contact us for an offline activation code. There is no charge but it offers less flexibility than online activation.

We also offer licensing options for running Aid4Mail in a virtual environment. Pricing is determined by the number of concurrent users plus the total number of users and installations. Contact us for a quote.
