Hi everyone, we are using WLM here in office but we have a problem reading and replying the calendar invitation (.ics format) sent by others. I have googled out the solution but most of solutions I found is to migrate WLM to Microsoft Outlook which is not really practical as not every user has Microsoft Office plus the process of converting WLM to Outlook is not easy and a bit time consuming.

I really appreciate if any of you sifus could help me solve this problem. Thank you in advance.
