I have a problem related to encrypted files..

I applied AIP to the users, I tried to send a mail containing an encrypted file and send this mail to the on-prem mailbox, But the user was unable to open this encrypted file with the label "encryption-only".

and also send a mail with the label "recipients only" and the suer couldn't access it.

    Hi @Ahmed Elsayed Riad Abdelhady Elkeay , without further information I have to recommend Joy's suggestion to verify your directory synchronization. Please let me know if you're still experiencing this issue and I can help you further.

    Thank you,
    James
