How to import OST file in Outlook
Microsoft Outlook has no function for importing OST files. This means it’s necessary to use tools or services from off-site software suppliers. Import of OST in Outlook results in conversion of OST to PST and opening of PST file with converted data in Microsoft Outlook. A detailed instruction is provided below:
- To convert OST to PST with the help of online-service and tools from the website https://www.osttopst.online
- To open the converted PST files in Outlook menu: File | Open&Export | Open Outlook Data File
Notes for the Microsoft OST 2 PST converter service:
- The size of the converted PST file may be considerably smaller than the size of the original OST file.
- The converted PST file will be saved in Unicode format as a *.PST file that is used as the default file format in Microsoft Outlook 2007 or later. This format allows you to store more than 2GB of data in a single file.
- The files are stored for 10 days starting from the time that the source file is uploaded to the server;
- The converted PST file will not be encrypted or password-protected.
Since the internal folder structure in the .ost file is slightly different from the .pst file, to search for folders merely open all the folders of the 1st and 2nd level in the .PST file in Microsoft Outlook. Usually, user folders are at the second level.
The size of the converted .pst file shows the actual size of information stored in the ost file. If you do not make archives and do not start Cleanup Tool regularly for the original Offline Storage Folders, then the .ost file size is only growing. As a result, only 5-10% of the file can be used for a real user's data.
Offline OST to PST Converter exports messages, contacts, appointments and other data from *.ost files as MSG files. The software converts and saves all data from .ost files to the .msg file format. Later, the user can drag and drop or import the saved *.msg files in any of the popular client software programs, including Lotus Notes, Microsoft Live, The Bat, Eudora, Incredimail, Mozilla Thunderbird, etc.
Microsoft Outlook has no function with which to import data from *.ost files. To open an *.ost file in Outlook, the Exchange Server and Windows Domain Controller must be working and available for user authentication in both of the respective services. Only after that is it possible to transfer the contents of an .ost file that is open in Outlook to a .pst file that is also open in Outlook.
If the Exchange Server or Windows Domain Controller isn't accessible or doesn't work, or if the user can't be authenticated, access to the data will be denied and Outlook won't open the .ost file.

“He can handle the task. Good even with an introductory explanation of PST and OST files. It is worth explaining the text that the service is worth it.”
“It is very nice, good health.”
“I didn't think I would run into a problem, but the quarantine took us by surprise. I needed to change the .ost file to .pst, and I was able to do that simply by uploading my file here. Outlook is now more convenient”
