Meeting Requests with ical format receiving as Plain Mails RRS feed

  • Question

  • Hello All,

    Am facing a problem with the meeting requests received as plain mails. The scenario is we are sending meeting requests using plain .net code which is generating ical and sending meeting invites. My client having an environment mail server "Exchange Server 2007" and their internal users receive the mail using the Out Look 2010. Meeting requests are working fine over there which are sent internally. Problem is occuring with the mails sent my application. The user is receiving the ical as an attachment showing as "not supported calendar message.ics".

    Please share your thoughts on this.

    Thanks.

  • Hello Rajani,

    From your description, seems your message format is not supported by Exchange 2007 Server, you need to check on your custom application, make sure the meeting request sent from your application is supported by Exchange 2007.

    Thanks,

    Evan
