OLM file format? RRS feed

  • Question

  • Does anybody know where I can get technical specifications for the .olm file produced by Outlook for Mac?  I know there are conversion utilities but I need to write my own code for this.  I see the document for .pst files but that is not the same thing.

  • Hi Jeff,

     

    Thank you for the question.  We have reviewed and confirmed that there is not formal documentation for the .olm file format.  The format is subject to change with not being covered in open specification.

    Thank you,
