File with .MBOX extension contains an email message box file which stores list of messages for given recipient in sequential order. MBOX is a text file, and each message referenced in such file starts with ‘From’ header and ends with newline character.
OLM is a database file format used by Microsoft Outlook for Mac systems. OLM files store email messages, calendar data, contact data, and application settings. OLM is a counterpart of PST format for Windows systems.
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 MBOX file after converting to OLM may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from MBOX to OLM 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 MBOX to OLM does not meet your expectations, you can simply try to find on the Internet a different version of your file in MBOX format, properly converted to a OLM file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file MBOX the desired result was not achieved, you can try to change the format of MBOX file to other than OLM. 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 MBOX file converted by someone else, and the attempt to convert it to OLM 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 MBOX file in its original format (without conversion to OLM file). Such a solution will be difficult to implement, but it certainly will give the best result.
