Updating Reoccurring Zoom Meeting via Outlook 365 Calendar

[JTQSD]

I have a user who is experiencing a strange issue updating a reoccurring Zoom meeting via Shared Mailbox calendar in Outlook 365. Whenever the user updates the reoccurring meeting by adding content to the body of the meeting message/details and clicks Send & Update, copies and paste new content within the meeting message body, and the content then mysteriously gets removed completely after the update is sent. Funny enough, the Zoom Meeting details remain there. 

Has anyone out encountered this issue? Whether this is an Outlook issue or Zoom issue?

Would appreciate any feedback
