I have imported 2 organizations(Account(type- abc, xyz) & events) data into one production organization.And created two users (salesforce platform license) called A, B and set the OWD is priavte for account and control by parent for activities objects and created sharing rules for assigning abc acocunts to User A (READ/WRITE) and xyz accounts to User B (READ/WRITE). User A seeing only "abc" type of accounts with read/write access and events(read/write) associated with abc accounts, it's working fine.
Problem: User A also seeing Events(read access) associated with "xyz" type of accounts on calendar when he logged in salesforce. User A must see only "abc" events not "xyz". How to solve this issue.
I really appreciate your help.
