To Enable active sync for an account, run the following command:
Set-CASMailbox -Identity abc@prems.onmicrosoft.com -ActiveSyncEnabled $True
abc@prems.onmicrosoft.com in the above commands, is the email address of the account on which we want to change the respective setting.
To check the current setting of the Active sync, run the following command:
