Are there ways to make Aid4Mail process emails faster?

If you are using an anti-virus, anti-spam, file indexing, archiving product or other software / plugin that monitors email messages, turn them off temporarily when using Aid4Mail. Doing so can significantly improve processing speed. You can also speed up processing by unchecking the “Do not add duplicate messages” setting on the “Export Options” screen.

Furthermore, starting with version 1.96, Aid4Mail uses a slower method for reading generic mailbox files, including those created by Mozilla Thunderbird and Eudora. It does so to ensure it doesn’t miss any emails when processing mailbox files that contain a mix of storage formats (e.g. a Mac or Unix mbox file imported in Windows Thunderbird with new messages added to it). If you are processing mailbox files that are entirely created by a single mail client, then you can increase performance without sacrificing reliability by using the /fast command-line switch. Example:

Aid4Mail.exe /fast

Starting with version 1.98, under Outlook 2003 and more recent, Aid4Mail uses a special MAPI feature to import/export mail from Outlook PST and MSG files, and Exchange server mail. The advantage with this new method is that it converts Unicode messages and certain special email types more reliably than the previous method. The disadvantage is that it is usually slower than the alternative method that does not use the special MAPI feature. Use the /MapiConvOff command-line switch to turn off the special MAPI conversion feature and use the faster method instead. Example:

Aid4Mail.exe /MapiConvOff

The two command-line switches mentioned above can be used together if necessary. Example:

Aid4Mail.exe /fast /MapiConvOff

Note that working on compacted mailbox files (i.e. those in which unpurged mail has been removed) can also improve conversion speed significantly. If you are responsible for migrating mail accounts in your company, you could encourage staff members to compact their mail folders before you start processing their data with Aid4Mail.
