Hi! According to the ActiveSync mailbox policy ”The maximum length a password can be is 16 characters.”. Reference: https://docs.microsoft.com/en-us/powershell/module/exchange/devices/Set-ActiveSyncMailboxPolicy?view=exchange-ps Also note the following: "When you enable password sync, the password complexity policies configured in the on-premises Active Directory override any complexity policies that may be defined in the cloud for synchronized users. This means any password that is valid in the customer's on-premises Active Directory environment can be used for accessing Azure AD services." Reference: https://docs.microsoft.com/en-us/azure/active-directory/connect/active-directory-aadconnect Best regards, Leon
