Details:

This
notification is to inform you that we recently investigated and corrected an
issue within the Yammer service that was causing files downloaded via the
Yammer Android app to not be encrypted when the policy was enabled within
Intune. This encryption issue was introduced during Yammer's adoption of
Intune's Mobile Application Management (MAM) policies. This issue only occurs
when your tenant admins enable these policies for your users.


"Allow
Save As"


"Encryption"

While the files
weren't encrypted, they remained within external storage on the Android device.




We've taken
corrective actions and released an update to the Yammer Android app via the
Google Play Store,

"https://play.google.com/store/apps/details?id=com.yammer.v1" target="_blank" rel="nofollow noopener noreferrer">https://play.google.com/store/apps/details?id=com.yammer.v1">https://play.google.com/store/apps/details?id=com.yammer.v1" target="_blank" rel="nofollow noopener noreferrer">https://play.google.com/store/apps/details?id=com.yammer.v1. Please take actions to update
the Yammer Android app to properly encrypt downloaded files.



We're providing this
notice as the Yammer Android app did not honor your tenant's encryption policy
in regards to Android file downloads via the Yammer app. As a result, any files
downloaded prior to the recent 5.6.27 update will not be encrypted. If your
organization requires this policy, we recommend all of your end users update
their Yammer Android app to resolve this issue for future file downloads. In
order for users to encrypt their previously downloaded files, they'll need to
update their Yammer Android app and remove the old downloaded files and
download again using the Yammer Android app to ensure that they're encrypted.



You can configure
your MAM policy to include conditional access in regards to the Yammer Android
app build number. This will ensure that the app is properly updated prior to
further usage.
