Outlook Msg Laravel Package
cosmira/outlook-msg
A PHP library for reading Microsoft Outlook .msg files without Outlook installed. Extract subject, sender, recipients, body, headers, dates, and attachments into structured data for email migration, search indexing, and archival workflows.
cosmira/outlook-msg is a PHP/Laravel package for reading Microsoft Outlook .msg files. It provides a simple API to parse email messages and extract their contents without requiring Outlook or COM extensions, making it useful for importing emails, attachments, and metadata into your application.
- Parse .msg files into structured email data
- Extract sender, recipients, subject, body, and dates
- Access and save attachments
- Laravel-friendly integration with a clean API
- Works without an Outlook installation
Frequently asked questions about Outlook Msg
- How do I install cosmira/outlook-msg in a Laravel application?
- Install it with Composer by running composer require cosmira/outlook-msg. The package is MIT licensed and distributed through Packagist, so it drops into a Laravel app without needing a Laravel-specific service provider. Pin the version in your composer.json and wrap the API in your own adapter class rather than calling it directly from controllers or Eloquent models. Because public adoption is thin, verify it against your PHP version in a short spike before committing to it.
- Does cosmira/outlook-msg require Outlook, Exchange, or the COM extension to read .msg files?
- No. cosmira/outlook-msg reads and writes MSG files natively in PHP, so it works on Linux workers and containers where Outlook, Exchange, and the COM extension are unavailable. That makes it viable for queue-based ingestion on typical Laravel hosting. Complex content such as RTF/TNEF bodies, embedded messages, and named MAPI properties may still parse imperfectly, so validate against real fixtures before relying on it.
- Which PHP and Laravel versions does cosmira/outlook-msg support?
- The package is a framework-agnostic Composer library rather than a Laravel-native one, so it imposes no formal Laravel release constraint and works anywhere Composer autoloading is available. Its supported PHP range should be confirmed from the package's composer.json on Packagist before adoption, since maintenance cadence is unverified. Test it against your application's PHP and Laravel matrix, particularly if you run older PHP versions.
- How do I extract attachments and the message body from a .msg file in PHP?
- Instantiate the package's reader against a file path or stream, then pull the properties you need: subject, sender and recipient details, dates, body variants, and the attachment collection. Persist attachments to object storage using generated filenames instead of the original ones, and map parsed metadata into your own DTO or model. Keep this logic inside a dedicated service class bound through Laravel's container so the dependency stays replaceable later.
- Can cosmira/outlook-msg write or create .msg files, not just read them?
- The library advertises both read and write support, but writer output should be treated as unproven until you round-trip files through real Outlook clients. For most Laravel use cases such as archival, migration, indexing, and support mailbox processing, read-only ingestion covers the requirement. Defer write support until read parsing is validated against a representative fixture set.
- Is cosmira/outlook-msg safe for processing untrusted user-uploaded .msg files?
- Treat every uploaded MSG as hostile binary input. Apply size caps, timeouts, process isolation, and queued jobs so a malformed file cannot exhaust your web workers, and scan attachments with antivirus before storing or serving them. Validate attachment types, keep files outside the public webroot, and return generic user-facing errors instead of exposing raw parser exceptions. Never parse untrusted MSG files synchronously inside an HTTP request.
- How should I handle large .msg files and memory usage in a Laravel queue job?
- MSG files are OLE/CFB containers and parsing is typically memory-bound rather than streaming, so large attachments and nested messages can exhaust PHP memory. Run processing on dedicated queue workers with a raised memory_limit, per-file size limits, and job timeouts, and scale those workers independently from web traffic. Log peak memory per file during your spike so you can set realistic caps before production.
- Can cosmira/outlook-msg parse encrypted, signed, or malformed MSG files?
- Encrypted and signed messages, malformed containers, and deeply nested embedded messages are exactly where third-party MSG parsers tend to break, and this package has no public evidence of handling them. Catch parser exceptions at your adapter boundary, log the failure with a file hash, and return a clear unsupported or corrupt file result to the user. Build a fixture corpus that includes these cases so behavior is known before launch.
- How do I test a Laravel MSG import feature built on cosmira/outlook-msg?
- Build a fixture-based contract test suite from anonymized real-world MSG files covering Unicode subjects and bodies, HTML and RTF alternatives, inline images, large attachments, nested messages, and calendar items. Assert on the normalized output of your adapter rather than on library internals, so the parser can be swapped later without rewriting tests. Add tests for corrupt and encrypted files to confirm your error paths behave. Run these in CI alongside your standard Laravel test suite.
- Is cosmira/outlook-msg actively maintained and production-ready, or should I consider alternatives?
- Adoption signals are thin, with roughly two GitHub stars, no known dependents, and a single public package, so treat it as a candidate technology rather than a proven dependency. Budget for owning the adapter, the fixture corpus, and upgrade tests, and monitor upstream releases and PHP compatibility. If maintenance stalls, the MIT license lets you fork or migrate to another parser or an external conversion service. Start with a bounded read-only use case and shadow-run against your current process before broad rollout.
