Converting Outlook OST files to PST files

  1. Launching the application.

When you launch the EdbMails software, a new window will open with a professional blue interface asking you to select one of two options. If you are a new user and want to try out the tool, click the Start Your Free Trial button. If you have purchased a working license, enter your login credentials to access the software. EdbMails does not require a serial activation key to be activated. The license is linked to the unique email address you provide when making a purchase. It’s also worth noting that EdbMails houses all of the recovery, migration, and conversion utilities in a single application. This shortens the installation process and does not necessitate permissions for multiple software installations. The free version allows you to test all of the options and features at your leisure, while the full-featured version is dependent on the license plan you choose. 

2. Selecting the OST file from your computer

If you prefer an OST conversion, select the OST to PST, Office 365, and Exchange operation from the main interface. Next, navigate to the OST file you want to convert on your computer’s hard drive and let the software recover the contents. If you’re wondering where to look for the OST file, it’s usually in C:Drive>User Folder>AppData, and then inside the Microsoft Folder. Before using this OST in EdbMails, make a backup of it.

3. Recovering the OST file

The software begins the recovery  process, and displays all the contents in an organized hierarchical format. We tested with a 10 GB OST file and it could recover the contents within a few minutes.

4. Selecting the required mail items

Following the recovery process, the main interface displays all of the mail items on the left pane. When you select it, it displays the individual mail items in the form of a list on the right pane. The bottom pane displays the mail items, which you can read. This interface is very similar to Outlook, which is great for those who are already familiar with the Outlook format.

5. The actual conversion procedure. 

There are numerous conversion options available, including HTML, EML, PST, MHT, Office 365, and Exchange. You can convert individual mail items in the right pane to HTML, EML, and MHT formats by clicking on them. You can export to Outlook PST, migrate to Office 365, or use live Exchange from the bottom pane. 

6. Review and make any necessary changes

After you have selected one of the conversion options from the bottom pane,  review the selected items and make any necessary changes here. There are also filter settings which will help you select only the mail items and folders for conversion. 

7. Save the files on your computer

Browse for the location where you want to save the PST. (If you chose the Export to PST option.) In case you have selected the Office 365 or live Exchange operation, navigate the corresponding windows, select the target mailboxes, and begin the import process 

8. Migration progress and completion

When everything is finished, the conversion or migration process starts, and a progress window appears. Following the completion of the conversion, the software displays a message, and you can view the entire conversion log history by clicking on the View Log button at the bottom. The time it will take to complete will be determined by the size of the OST file and the number of mailboxes you have. Once the entire PST file is available to you, import it into MS Outlook to view all the contents.
