Greetings Aboulola,
 
Whenever you manually delete a mailbox in Exchange, the information is synchronized automatically after sometime when the syncing of mailboxes record takes place inside HC9 database.

Thanks team for reply
 
but my question regarding deleting user in on-premise AD not exchange
BUT it is not reflected in cloud AD (HCDirSync Tool)
 
kindly provide me the possible reasons for such behavior ?

Your team might be using non-administrators user account in Local AD Setting (Utility interface) who do not have privileges to view the Active Directory deleted objects container.
Please check MS article https://support.microsoft...y-deleted-object 
 
For further discussion I will request that you please send email to our team member who have been assigned to your Organization.
