Some Calendar items for some users don't appear in Exchange Mailbox (OWA), but are visible in Outlook. (4242327)

Some Calendar items for some users don't appear in Exchange Mailbox (OWA), but are visible in Outlook.

Migrator for Notes to Exchange environment details:

MFNE: 4.12.1.99 Windows 20012 R2 64Bit English (Virtual).
SQL: SQL 2012 Windows 20012 R2 64Bit English (Virtual).
Exchange: Office365 Cloud.
Outlook: Outlook 2013.
Lotus Notes Client: 9.0.1
Domino Server : 8.5.2

After upgrading from MNE 4.12.1.11 to 4.12.1.99, calendar acknowledgement was accepted before migration and all calendar responses (sent by another user or external user) were also accepted.
This issue wasn't happening with the MNE 4.12.1.11 version.
The problem is after migrating a mailbox, some calendar entries for some users don't appear in the Exchange mailbox viewed from the OWA, but are visible from Outlook.

The MNE Verbose log indicated that the calendar item was migrated:

This issue has been confirmed as a defect and registered under TF00603364.
The main problem is that some calendar items are being misclassified as acceptance notices, instead of regular calendar items.
They are unfortunately being added in the calendar, but are not fully correct.
Strangely enough, OWA will not show these items, whereas Outlook does.

A hot fix version of MNE will be will be worked on as soon as possible.
