Searching inside MSG and EML files

Follow this guide to perform searches for any words in the subject, body, attachments, sender name, recipients of MSG and EML files. Searching content and attachments of EML and MSG files saved to network share and local drive.

Search basics

  • The search tool uses wildcard matching searches when you type in a number, word or phrase in the Search box at the top of the message list. For example, if you type mail into the Search box, it will return messages that contain mail, Mail, gmail, and E-mails. By default, searches are case-insensitive. To make your search case-sensitive, check the checkbox Match case in Search options.
  • When you type specific words to include in the search, software scans both email messages and embedded email attachments (.msg, .eml files).
  • When you type in an email address, the search tool will return all messages that contain that email address anywhere in the sender name, subject, message body, or attachments. To limit your search results to emails from an email address, type in the search box.

Using Regular Expressions

When searching for a text string that contains wildcards (*, ?) or white spaces, the software automatically converts them into their equivalent regular expression patterns. Additionally, a minimal set of characters (\, +, |, {, [, (,), ^, $, ., #) in your search query is replaced with their escape codes. To match a character with special meaning such as (*, ?, "), you need to use an escape sequence prefixed with a backslash (\).

Use the @ special character to initiate a regex search with your specific regular expression pattern. The @ special character serves as a verbatim identifier, indicating that a string literal is to be interpreted verbatim.

Type this To find this
@"(?:\"50%\" rebate\*)" "50%" rebate*

License: Check the order page of your product to verify if regular expression search is available in your license plan.

Please note that while most regular-expression searches can be executed very quickly, it's important to be aware that regular expressions can be constructed in a way that consumes arbitrary amounts of time and memory during processing.
