Allow admins to remove Rights added to attachments when encrypting with the new OME
The new Office 365 message encryption OME automatically adds rights to attachments and says who can open the attachment when encrypting an email. A Lot of our recipients cannot open the attachments because the rights/permissions were added wrong to the attachment. I also, we want them to beable to share the attachment but they cannot because it is rights protected. Admins should be allowed to not have rights protection added to an attachment when we simply want the email encrypted. I am already seeing alot of issues with this and people not being able to open attachments. It will be a big mess if you do not allow to not add rights protection to attachments.
On 8/3/2018 a Microsoft rep said "Then ability to remove encryption from attachments for all recipients for the Encrypt-only template is coming soon. It will show up as an IRMConfiguration setting DecryptAttachmentForEncryptOnly. Eta is 1 month for full worldwide deployment."

Hopefully this happens. A majority of O365 Business users do not need to add specific rights managements to files in an encrypted mail. With the above MS Rep answer and allow the decryption of OMEv2 attachments when sending to other O365 tenants will solve most issues users are having with IRM. There is no way you can get rid of OMEv1 without fixing this OMEv2 problem first.
I'm having the same problem. Users cannot download attachments on encrypted emails sent to them if they are using a Google account (or other 3rd party email provider).
