Dear All I apologize for this question related to IT safety rather than science and the use of Larch. Today, I installed Larch for Windows on an institute computer using the latest Windows 64-bit binary installer (0.9.68). Now I got the following alert from our IT security: “The process c:\users\%USER%\appdata\local\xraylarch\python.exe accessed Outlook files. The user who ran the process was XXXX. The accessed files were: XXXX.pst, YYYY.pst”. It seems that during the installation of Larch, python.exe accessed some outlook archive files in another folder on the C drive, and I do not know if this should be a matter of concern. Has anyone experienced a similar behavior before, or does anyone with Larch/python skills have an explanation for this? Cheers, Andreas
