Outlook stores all your data, including emails, contacts, calendar events, tasks, and more. These data files are called Personal Storage Table files. In short, we denoted this as the PST file. These files contain all your Outlook data and are primarily used when you set up an email account that uses POP3, IMAP, or HTTP. Although it completely depends on your Outlook version, you might also encounter Offline Storage Table (OST) files. However, if needed, you can convert an OST file to a PST file.
If a user decides to move their data to a new computer, then it is quite appropriate action to keep their email life uninterrupted. Here are some of the major benefits of performing this action:
To make your Outlook data available on a new system, you need to move the PST file properly. Below are the most effective ways to transfer it without losing any emails or contacts.
Although this method is the most direct and works well if you already know where the PST file is stored. So, the basic point is you have awareness of where exactly your PST file is stored.
If you want to choose specific folders or ensure a clean export, Outlook’s Import/Export feature is a good option.
If a user has no any external storage, cloud storage is a simple way which will be helpful to transfer Outlook PST to new computer:
Sometimes, just moving a PST file is not enough. If your Outlook on the old computer was using an OST file (created when connected with Exchange, IMAP, or Office 365), you cannot copy it directly to the new computer. Outlook does not let you open OST files manually, which makes the transfer difficult.
In such cases, the Aryson OST to PST Converter is very helpful. It converts OST files into PST format. So that you can easily import into Outlook on your new system. This way, users can move all their emails, contacts, and other data without losing anything. Also, you do not have to worry about the compatibility. Because this is compatible with different OS and all versions of MS Outlook.
If you want to keep your emails, contacts, and calendars safe, then it is important to move your Outlook PST file to new computer. As we discussed, this can be done in different ways, such as copying the PST file manually, using Outlook’s export and import feature, or moving it through cloud storage. These methods are useful but can become time-consuming or risky when handling large or damaged files. In situations where Outlook uses an OST file instead of a PST, manual methods are not enough. In that case, use the above-recommended software and transfer Outlook PST to new computer.
Ans: Yes, you can copy PST files using a USB drive or external storage. However, large or corrupted files may cause issues, so careful handling is required.
Ans: In Outlook, go to File > Account Settings > Account Settings > Data Files. The file path will be listed there. You can then copy it from that location.
Ans: No. OST files cannot be opened manually. You need the Aryson OST to PST Converter to convert the OST into PST before transferring.
Ans: Open Outlook, go to File >> Open & Export >> Open Outlook Data File, and select your PST file. Your emails and other items will appear.
