Struggling to Convert TGZ Files to PST? Explore the Best Methods & Solutions
By Veloria Hales 31-08-2026 10
Introduction
Zimbra maintains mailbox information in TGZ archive files. These files are useful for backing up or transferring email data. But this information is not as easy to retrieve in Microsoft Outlook, which mostly works with its own data formats, including PST. This distinction is problematic when users migrate from Zimbra to Outlook or need to access archived Zimbra emails in the Outlook environment.
You can convert TGZ files into PST to make mailbox data easier to access, organize, and manage in Outlook. However, the right conversion strategy depends on the volume of data, your technical knowledge, and the level of control you need throughout the migration.
Typically, you have two choices: a manual procedure or a professional TGZ converter tool. For smaller amounts of data, a manual method can work, while dedicated software can facilitate larger or more complex migrations.
In this post, we will let you know the methods available, the benefits of creating an Outlook-compatible PST file, and how a dedicated tool can be used as a professional solution.
Reasons to Convert Zimbra TGZ Files to PST
TGZ and PST are different and are related to different email environments. TGZ is mainly used in Zimbra mailbox exports, while PST is an Outlook data file that saves email messages and other mailbox data.
Converting the archive to a file that can be used with Outlook can be useful in the following cases:
- Microsoft Outlook is replacing Zimbra for users.
- Zimbra emails are archived and are only accessible through Outlook.
- Organizations are integrating mailbox data into an Outlook environment.
- Users wish to save a local copy of key mailbox information.
- The archived email data is to be imported into Outlook folders.
- We are not using Zimbra anymore, but the historical emails need to stay accessible.
The PST file is a more flexible way to work with the converted mailbox data rather than working with an archive, which is not directly supported by Outlook again and again.
Why is TGZ to PST conversion difficult?
At first glance, changing an archive seems like a straightforward file format change. But email migration is actually a lot more than just changing a file extension.
A mailbox archive can have multiple folders containing messages, attachments, and other related information. When migrating, users should consider how the source data will be handled and how the resulting Outlook data will be structured.
Manual conversion is particularly inconvenient if the archive contains a lot of mailbox information. Some intermediate activities may need to be performed by users before data can be imported to Outlook.
This makes choosing the right Zimbra mailbox transfer solution the right way to simplify the entire procedure.
Manual Method for Converting TGZ Data for Outlook
A manual technique could be considered for users with a small amount of mailbox data. Another option would be to extract the TGZ archive and then use Zimbra to export or retrieve the mailbox data and then import the data that is compatible into Outlook.
Zimbra TGZ Extraction and Outlook Import Method
Steps to follow:
- Locate the TGZ File: Create a backup copy of the original Zimbra TGZ archive.
- Extract the TGZ File: Extract the TGZ archive using a suitable archive utility.
- Access Zimbra Data: Open or restore the extracted mailbox data through the available Zimbra environment.
- Export Mailbox Data: Export the required emails into an Outlook-compatible format using Zimbra options.
- Open Outlook: Launch Microsoft Outlook on your Windows computer.
- Import the Data: Import the exported mailbox data using Outlook's supported import options.
- Save as PST: Organize the imported data and save it in an Outlook PST data file.
- Verify the Data: Check emails, folders, attachments, and other important mailbox information.
Disadvantages of the Manual Approach
The manual way can be reasonable for a small mailbox, but when you are working with several archives or large mailboxes,s it might be time-consuming. There can also be multiple intermediary phases and a need to be technically familiar with both Zimbra and Outlook.
If you are dealing with large archives, consider using an automatic email migration solution instead of a multi-step manual approach.

Manual Method Vs Professional Conversion
The choice between the two methods depends primarily on the magnitude and complexity of the migration.
Factor | Manual Method | TGZ to PST Conversion Software |
Technical expertise | Needed | Not required |
Massive mailbox Conversion | Less Convenient | More Suited |
TGZ files (many) | Difficult | Easy to use |
Intermediate steps | Repetitive Steps | Streamlined workflow |
Best for | Small, simple migrations | Frequent or significant migrations |
If only a small amount of data has to be moved and the needed Zimbra environment is available, a manual approach can be adequate. If you want to make the process a little easier, special converting software can cut down the stages.
Advantages of Keeping TGZ Data in PST Format
The primary advantage of creating PST output is that it is more compatible with Outlook-based workflows.
Easier to Reach Outlook

Migration Simplified
Organizations migrating from Zimbra to Outlook can utilize PST as an intermediate or destination format to move mailbox data into the Microsoft environment.
Central Mailbox Management
The PST format of historic Zimbra data can make it easier for users who typically work in Outlook to manage both previous and recent correspondence from a familiar interface.
Conclusion
There is no need to convert different file formats frequently to transfer mailbox data from Zimbra to Outlook. The conversion from TGZ to PST is a useful solution for users to access the history mailbox data in Outlook.
