IBM Security MaaS360

Hi all,

We're getting excessively high mobile data usage on the Samsung email app, across random users (e.g. 5-10 per month crop up). When I say excessive, I mean incredible amounts. Some users up to 80gb just on the email app, which if you consider the largest attachment size with Exchange of 20mb you can see that 80gb is pretty much impossible especially where most of our users have 1gb mailbox limits!

We enrol as Android Enterprise DO, with the app in the App catalog that gets pushed down to the device upon first enrol. Within the app config we have the exchange details, as by using ActiveSync settings in the policy never pushes the mail setup to the device in Android (iOS works fine doing it in the policy).

By removing the app and pushing it back to the device again resolves the issue.

I know I can add an expense policy and alert/block devices that hit a certain level however that's not the root cause. I simply cannot find any reason for this happening, and it's causing us tension as we use a data allowance from our service provider which we are likely to breach if we don't find a fix.

Any help appreciated.

Hi Matt,

Would you mind opening a case with our support teams about this?  We may have to open a ticket with Samsung to help investigate, and we'll need to gather some sensitive data.  I did a brief search through some Samsung forums and see some similar reports, but they're a few years old, and the most "helpful" suggestion was to use a different mail app.  Just mention in the case that I asked you to reach out and I'll get it routed to the right people.

Thanks Matt - have opened a case. Would be great if it could go across to Samsung as this is a serious pain point for us.

Could equally be something within our policies or app config causing this, however then I would expect it to hit every device rather than just a handful a month.
