Online – Data retrieval failures occurred
One of 3 Exchange Servers running on Windows Server 2019 returns “Online – Data retrieval failures occurred” I have tried to fix it by following this fix.
I have also tried:
cd C:\Windows\System32\wbem\Autorecover
Now, /f %s in (‘dir /b *.mof *.mfl’) do mofcomp %s
However, neither do not seem to fix it. Do you have any other suggestions?
Hi Name, thanks for reaching out.
to resolve your issue, you can try these steps:
Change a Registry Keyword: Another user reported success by modifying a registry keyword. Make the following change:
Navigate to
– [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WINEVT\Channels\Microsoft-Windows-Kernel-
IoTrace/Diagnostic]
– Modify “Enabled=dword:1” to “Enabled=dword:0”
Increase the MaxEnvelopeSizekb: You can try increasing
the MaxEnvelopeSizekb. Here’s how:
– Run Powershell as Administrator
– Execute the command: Set-WSManInstance -ResourceURI winrm/config –
ValueSet @{MaxEnvelopeSizekb = “700”}
If you have any questions, don’t hesitate to ask, we’re here to help you further if needed.
Your VAF Team.
