Explore the key features that ensure accurate and dependable OLM to Gmail data conversion
See the practical use cases where SysInfo Software simplifies OLM to Gmail data transfer.
When Mac Outlook users decide to switch email platforms, Gmail is the most easily accessible platform. However, Gmail does not support OLM format directly; you need to convert it to an intermediary format. Therefore, OLM to Gmail Converter Software is the most effective solution for direct migration of emails. It migrates OLM emails, attachments, contacts, and other mailbox data to Gmail without manual steps.
In many real-world situations, users no longer have access to Outlook for Mac or are working on a Windows system. As a result, manual migration of OLM files becomes impossible. SysInfo Software eliminates the dependency on Mac Outlook and reads OLM files independently. Thus, SysInfo OLM to Gmail Migrator is ideal for working on a new system or Windows Operating System.
Many businesses and IT administrators often manage multiple OLM files from different users or departments. But migrating so many files one by one is an error-prone and time-consuming procedure. Unlike any manual process, this software can handle multiple OLM file conversions at a time. This ensures faster migration, consistent results, and minimal downtime while moving teams or entire organizations to Gmail.
Get clear insights into how every feature functions and what it delivers before you choose the software.
Migrate OLM Files to Gmail Account
SysInfo OLM to Gmail Migration Tool is an exclusive software for direct migration of OLM files to a Gmail account. It involves no complex setup and connects to Gmail using modern authentication. During migration, the tool ensures all emails, folders, and metadata are mapped accurately to Gmail folders. Moreover, it transfers email content, headers, timestamps, and folder structure with utmost precision, which are preserved during migration.
Process Multiple OLM Files
Migrating OLM files individually is a hectic and risky procedure, especially when you have hundreds of thousands of files. This software supports bulk OLM file processing. Users can add and migrate multiple OLM files in a single session. With the Select Files and Select Folder options, users can upload unlimited Mac OLM files to the software, and the tool processes them all together. Most importantly, this does not affect the processing speed.
Convert OLM to Outlook PST and more
Apart from OLM to Gmail Migration, this software offers to convert OLM into other formats for backup. You can choose to save OLM files to multiple email, image, document, spreadsheet, and Web formats for wide accessibility. The software offers to convert OLM to PST, PDF, MBOX, EML, HTML, CSV, DOC, DOCX, ICS, VCF, JPG, PNG, GIF, and many more output formats. Users can choose to save OLM data in any of these with ease.
Migrate Emails to Multiple Email Clients
The SysInfo OLM Migration Software also lets users transfer OLM emails to multiple email platforms. This involves migrating OLM to Office 365, Thunderbird, and Google Workspace. You can also import OLM to IMAP Server like Yahoo Mail, Zoho Mail, Yandex Mail, AOL Mail, and Hotmail (Outlook.com). The login procedure is simple and does not require the original password, ensuring no data is altered and confidentiality is maintained.
Preview Mac Outlook Mailbox Data
How about if you have controls to verify emails, avoid unnecessary data transfer, and ensure that only the required mailbox items are moved? This is possible with the Preview feature. The SysInfo software provides a detailed preview of OLM mailbox data in a tree-structured panel. The preview panel shows emails, subjects, senders, recipients, dates, and attachments to verify data accuracy before migration.
Converts Different-Sized Files
If you have been using Mac Outlook for years, OLM files can get really bulky and large. However, it's possible to convert them with ease. Whether the OLM file contains a few emails or years of mailbox data, the software processes it smoothly without performance issues. Moreover, it prevents crashes and maintains data integrity even when migrating complex OLM files.
Save Contacts and Calendar on Desktop
This feature allows users to extract and save Mac Outlook contacts and calendar data from OLM files directly to the desktop. Data are stored in their respective formats without alteration. Instead of limiting the migration to emails only, the software ensures that important address books, meeting schedules, and event details are accessible locally.
Auto Map OLM Data to Gmail Folders
SysInfo Software has newly launched a feature to auto-map OLM data to default Gmail folders. Emails from the respective folders are automatically placed in their corresponding Gmail folders without requiring manual mapping. The tool is trained well to align all OLM mailbox folders with Gmail’s default folder with precision.
Migrate Emails Without Duplicates
SysInfo OLM to Gmail Migration software is the best choice to avoid Mac Outlook mailbox clutter. The software includes a duplicate removal feature that detects and skips identical emails during migration. Select parameters on the basis of which the software compares emails: sender, recipient, subject, and message body. This ensures that only unique emails are migrated to Gmail.
Date Specific Migration Feature
Instead of the entire mailbox, if you wish to migrate data from a specific time range, use the Date Filter feature. You simply need to set a start date and an end date to migrate emails selectively. With this feature, users can extract only relevant emails based on business, project, or compliance needs. This minimizes data volume in the destination mailbox and reduces migration time.
Eliminate Attachment Files
Emails may often contain different types of attachment files like Documents, PDFs, Images, and more. But, there may be scenarios when you do not want bulky attachments, especially if they are unnecessary or too large. Select the “backup or migrate OLM without emails” option and reduce Gmail storage usage.
Custom Folder Name
With the Custom Folder Name feature, users can define their own name for the output folder in the Gmail mailbox. Select the feature and assign a name of your choice that will help you easily locate and manage migrated data without manual reorganization. You can choose a name based on your preference.

Run a free version of the software to test its functionalities before purchasing. You can evaluate preview, filters, interface, and migration accuracy by converting upto 50 emails per folder for free. This is for users to make informed decisions. For complete OLM folders migration, purchase a premium license.
