File with .PST extension contains Microsoft Outlook, Messaging, or Exchange Client user personal data. PST files store data using open format developed by Microsoft, Personal Storage Table.
OST file format is used by Microsoft Outlook mailing software. The file can contain data such as email messages, tasks, calendar data or contacts. OST files are used as offline mailbox files if applications is not connected to Micr o soft Exchange server.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the PST file after converting to OST may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from PST to OST to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting PST to OST does not meet your expectations, you can simply try to find on the Internet a different version of your file in PST format, properly converted to a OST file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file PST the desired result was not achieved, you can try to change the format of PST file to other than OST. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your PST file converted by someone else, and the attempt to convert it to OST on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the PST file in its original format (without conversion to OST file). Such a solution will be difficult to implement, but it certainly will give the best result.
