TrustVare TGZ to PST Converter Review 2026: Features, Usability, Benefits & Limitations

Introduction

Zimbra TGZ files are a great way to save mailbox data, but retrieving that data in Microsoft Outlook can be a challenge if the data you need is archived in a format that Outlook doesn’t accept natively. This is where a TGZ to PST converter can help. Converting the Zimbra mailbox data into PST makes it easier to view emails and other mailbox items through Outlook.

Manual migration can involve multiple steps and can become tedious with multiple TGZ files or large mailbox archives. A dedicated converter can help here, giving filtering, preview, batch processing and direct export options.

In this review, I am going to check out the features, workflow, user-friendliness, compatibility, pros and cons of the TrustVare TGZ to PST Converter to see if it can be a viable option for Zimbra to Outlook transfer.

Why Do Users Need A TGZ to PST Converter?

There are many reasons Zimbra users need to migrate their archived mailbox data to Outlook: platform transfer, email archiving, backup access or organizational changes. TGZ is related to Zimbra mailbox exports and PST is a commonly used file format in MS Outlook, so it is essential to do a conversion if users intend to work with the archived data within Outlook.

The challenge is even greater when your mailbox is full of many emails, contacts, calendars, notes, projects, or other objects. Doing the components by hand can be quite time-consuming and potentially make data management more complex.

Another option is to utilize a dedicated Zimbra to Outlook migration tool which is a more systematic solution. It allows the user to load TGZ files, see the mailbox content, pick the appropriate data and export it to PST.

Overview of the Software

TrustVare TGZ to PST Converter is a Windows-based mailbox conversion tool that helps export Zimbra TGZ data files to PST file format. It allows single file and batch conversion. It can convert selective TGZ files using filtering settings. It also allows previewing the imported mailbox before conversion so that users can deselect the unwanted folders.

The software is a standalone solution so the users don't have to install Zimbra or Microsoft Outlook to do the conversion and can then open the resultant PST files in compatible Outlook versions.

Features That Help in the Conversion Process

Batch Processing of Multiple TGZ Files

It is inefficient to work with individual mailbox archives. The software allows for batch conversion, that is, the processing of numerous TGZ files at once. This might be especially helpful if a company has multiple Zimbra mailbox archives to move.

Export Data Selectively

You don't have to move every mailbox item. File Mode and Folder Mode provide the choice to pick specific TGZ files or directories. The preview area also provides users with the ability to select the needed mailbox content prior to export.

Preview Before Conversion

For large archives, a preview tool can be useful. Before the export process, users can preview the accessible mailbox data, which makes it easier to determine the folders that actually need to be converted.

Maintain Mailbox Organization

It is crucial to maintain the original structure during TGZ mailbox transfer. The application keeps the structure and features of the exported data, including mailbox objects such as emails, contacts, events, notes, and journals.

No installation of Zimbra or Outlook

The conversion procedure is more flexible due to the stand-alone nature of this application. Users can handle TGZ files without installing Zimbra or Microsoft Outlook on the converting system.

Compatibility with Outlook Versions

The converted PST files are for usage with Microsoft Outlook and the official page mentions compatibility with Outlook 2019, 2016, 2013, 2010 and older.

How Does This Tool Work?

The conversion process follows a straightforward workflow:

Step 1. Download and install the converter on your Windows OS.

Step 2: Choose File Mode or Folder Mode according to the type of TGZ data you wish to add.

Step 3: Search and upload appropriate TGZ files.

Step 4: Review the mailbox data and pick folders or items for export.

Step 5: Select PST as output format and choose a destination location.

Step 6: Initiate the conversion and wait until PST files are created.

System and Usability

The software is designed to be used in the Windows environment and it has a rather simple UI. It has a guided workflow, which can be helpful for those who don’t have advanced technical knowledge.

Another practical thing is that the tool can meet individual and business needs, and its batch-processing capacity makes it more ideal for larger mailbox collections than a file-by-file method.

Pricing & Trial Availability

This software offers Personal, Business and Enterprise licensing. You can also try the application before purchasing it with a trial version. The trial can export up to 25 files, and the licensed edition can be used with no time limit. You can check the official page for further information.

Advantages and Disadvantages

Advantages:

• File Mode and Folder Mode are available
• Mailbox export selectively
• Preview offered pre-migration
• Preserves mailbox structure

Conclusion

This Converter is a practical option for users who want to convert Zimbra mailbox archives to Microsoft Outlook using a more systematic approach, as it provides batch conversion, selective conversion, a preview option, and independent operation.

The largest benefit is the amount of control you have before converting. It lets users see the mailbox and select the appropriate files or folders instead of blindly exporting every item. Larger email migration projects can also be less work if you can process more than one TGZ file.

However, before selecting the software, users should consider the Windows reliance and trial limitations. So, overall, it looks like a good solution for users that need a dedicated Zimbra to Outlook conversion method instead of a difficult manual process.
