V10 - Exchange item restore fails after Veeam upgrade

[superdevo]

Hi guys,
we're having a pretty serious issue.
After V10 upgrade we get a 401 unauthorized error when trying to restore emails.
Currently we're running Exchange on prem 2010 SP3 fully patched.

I have a case open with Veeam (04311007). So far we've verified that full access and impersonation is granted and working. EWS is reachable. Tried with IP and FQDN, tried a specific congif to avoid system proxy:

<Veeam>
<Ews UseSystemProxy="False" />
<Exchange>
<Restore>
<Autodiscover UseSystemProxy="False" />
</Restore>
</Exchange>
</Veeam>

And we still get the same issue. Has anyone seen anything similar?

Hello,
I just read through the case and the setup is fully supported. I'm not sure whether it is really related to a V10 upgrade or whether something else.

Forum search does not show any results for your issue, so I can only recommend to continue with support.

Best regards,
Hannes

Veeam uses EWS to communicate with the server. You can check with your used user and a script if this is working.
