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.
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.
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 OST file after converting to PST may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from OST to PST 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 OST to PST does not meet your expectations, you can simply try to find on the Internet a different version of your file in OST format, properly converted to a PST file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file OST the desired result was not achieved, you can try to change the format of OST file to other than PST. 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 OST file converted by someone else, and the attempt to convert it to PST 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 OST file in its original format (without conversion to PST file). Such a solution will be difficult to implement, but it certainly will give the best result.
