Hello everyone!
We are facing the problem below:

After the mailbox migration from Lotus Notes 7.5 to Exchange 2010, meetings were scheduled as recurring in Lotus Notes, errors are displayed in the recipient to accept the invitation in Outlook 2010.
The client used Microsoft Transporter Suite for Lotus Domino in Exchange 2007 server.
The error error message when the recipient tries to accept the meeting.
