Export emails to PST Exchange 2016 CU2

Guys, I'm going through a curious problem.

Only in Exchange 2016 CU1 and CU2 this happens.

If we use the command that exports to PST an email from a user box, the Exchange is always exporting.

For example, an account with 4GB e-mail, export it to the PowerShell, it is with 10GB, 30GB, 50GB and will only increase and never ending, ever ...

Even the space of 1TB of hard drive over ...

I've done it in 4 different installations of Exchange 2016 and always has this symptom.

Has anyone ever experienced this ?
