Ics files

Hello, sorry if already asked this question.

I have a. Ics and I'm sending it attached in the email, but when I open the email with attachment, Zimbra does not automatically identifies how it does with files. Ics of google calendar. When I do a google calendar meeting in March and the option of sending the invitation, google sends an email with an attachment, the. Zimbra ics and identifies this as iCalendar file and the header of the email (along with the subject of the e-mail) appears options to "Accept" or "Deny" this meeting.

The problem is that the file I'm sending is normally imported by more zimbra is not identified automatically.

The version of Zimbra is 6.0.4_GA_2038. In version 5.0.4 it worked normally.

I do not know if I did understand.

I am sending you attached the file.
