Outlook problema de vcalendar

Hi @Antonio Leonetti ,
Please kindly understand that currently in Microsoft Q&A we only support English language. And I am trying to read your issue by machine translation, if there is any mistakes, please try to re-describe your issue in English so that I can better understand and help solve your issue.

I'm trying to retell your issue: when you create the new meetings and invite other people, there's an attendee who still sends the emails with multiple Vcalendar characters instead of the normal meeting response, right?

If so, for testing, please contact with other people to send a same meeting invitation for this attendee by the same way and check if the issue has any difference.

If the issue still exists, due to the issue only happens to an attendee, it may be more related to his Outlook client and working environment. Did he make any special operations about Calendar in Outlook(such as import vCalendar file, modify Outlook script code, or others)? To further troubleshoot this issue, please check the difference between his environment and others’ who could respond normally, such as the Outlook version, add-ins, third party tools or others.

If the issue just happens to you, to further analyze it, please log in to your Web mail, then recreate a new meeting and invite same people, if you can receive normal response, the issue may be related to your Outlook client. So how do you create your meeting , by New meeting option in Outlook or other tools? If you use other tools, please try to create the meeting by New meeting options in Outlook and invite the same people to check. If it can work normally, the issue may be related to your tools and add-ins.

Any update, please feel free to post back.
