Updated Regarding of Appointment not reflecting in Account's Activities

Hi,

I have an Account wherein 2 Appointments appear in the Activities section. I updated the Regardings of those 2 Appointments to point to different Accounts. However, the Appointments still shows in Activities of the Account it belonged to originally. Also, this Appointment shows in the new Regarding Account.

Additionally, the owner of the Account record has been disabled in CRM. Could this be a reason for this? The user also used CRM For Outlook to keep track of Appointments. Kindly help.

Thanks.
