Hello!
The Problem:
No Exchange LOG truncation after full backup of an Server 2016 VM. We use Exchange 2016.
But it only is a problem within VMs where the guest OS is Windows Server 2016.
We use DPM 2016 to backup multiple exchange Servers from an Hyper-V Cluster.
We take full backups from the VM. Every Exchange Server is in an different Domain.
The backup integration service was activated and updated.
It works perfect on every 2012R2 server. On 2016 server, not matter which updates or cu we use. Also the latest DPM Update did not help.
The problem also occurs on fresh installations of Windows 2016 + Exchange 2016.
When I install the same configuration on an fresh Windows 2012R2 it does works instantly.
When I check the exchange 2016 database on the Windows 2016 server there I no date in “last full backup”.
Dirty workaround:
DISKSHADOW
ADD VOLUME “Database Volume”
BEGIN BACKUP
CREATE
END BACKUP
When I use this workaround, exchange starts the log truncation and I also see an date in “last full backup”.
I contacted the Microsoft support multiple times and was pushed from DPM to Exchange to Windows to DPM. All the way around and around. Microsoft support asks me the same question 100 times and gives me useless "try this, try that" support calls. I
also had multiple occasions of excellent support. Not on this problem.
There is no problem when I use “VSSSADMIN LIST PROVIDERS/WRITERS”.
I don´t see any relating problems the eventlog.
For me one thing is clear, it must have something todo with the integrations service. Something has changed here but I can´t find the missing link…
I also did a technet topic in the German forum… no replies there.

Hopefully you can help me.
