Out Of Office is not working for External Users – Exchange 2013

I have seen an issue with Out of Office emails are not working for External user, after checking few things I found that auto-reply has been set to false on my exchange, to check auto-reply setting and enable auto-reply please use below commands.

Get-RemoteDomain Default | fl AllowedOOFType, AutoReplyEnabled, AutoForwardEnabled

If AutoReplyEnabled is false, use below command to enable it.

Set-RemoteDomain -Identity Default -AutoReplyEnabled $true. 

When OOF is enabled, all reply emails are sent using Return-Path:<>  (=empty), when your email gateway/smart host detects this they may drop the email so the external sender is not notified that you are out of office.

There is no resolution to this on the Exchange 2013 side of things and you must contact your smart host provider to see if they can disable this “feature”.

To check if you are running a smart host, in the Exchange 2013 EAC browse to mail flow then select your Send Connector and then edit. you will then see the smart host option.

To workaround this issue I have created an automatic reply using a template works without any problem, Please find the below steps to create an automatic reply on outlook.

Please follow the below steps:

Step 1: Open outlook – File – Info – Automatic Replies


Step 2: Select Automatic Replies and select send automatic relies and then select rules at the bottom.


Step 3:  Select Rules and click Add Rules


Step 4:  Select Add Rule and tick the check box Reply with and click Template.


Step 5: Create a template with your out of office message and leave blank in from and to fields.

I found this solution working for me with out any further changes on smart host.



HowTo: troubleshoot and fix VmWare ESXi boot stuck at ‘loading ipmi_si_drv’


The first post that urged me to write a new blog because of several hours of head banging against wall, scratching my hair and relentlessly typing on keyboard with random hits as if i caught up on some shockwave.

Yes, the VmWare ESXi clueless error, that when you are running this baremetal hypervisor, it gets stuck during loading stage, where its loading all modules, almost to end of process, it gets stuck with following message:

Loading ipmi_si_drv

After much of docs reading and agonising go-through ESXi manual, i finally figured out the solution.

Here is what you need to do:

Step 1: Restart your machine. Its always good to go for the ‘when-nothing-works-try-this’ solution 🙂

Step 2: Be very quick and sharp about this step as it needs to be done in matter of seconds.

The moment you see a black screen with progress bar saying LOADING HYPERVISOR , enter

Unable to connect to the requested VDP appliance

Today I came across a situation where I am unable to connect to my VDP appliance and come up with below error.




there is no problem connecting to VDP configuration.

  • In the /usr/local/avamar/var/vdr/server_logs/vdr-server.log file, you see an entry similar to:

    YYYY-MM-DD HH:MM:SS,MS ERROR [$1]-server.VDRServer: VDRServer.getVCenterClient cannot obtain VCenterClient  java.lang.NullPointerException: VCenterClient list is empty

  • Also in the vdr-server.log file, you may see an entry similar to:

    YYYY-MM-DD HH:MM:SS,MS INFO [http-xxxx-exec-x] -impl.X509TrustChainKeySelector: Failed to find trusted path to signing certificate. 


This issue occurs with the date and time doesn’t match with VDP appliance and vCenter server or ESXi host.

Check the ntp settings are configured correctly on your VC and ESXi hosts. To resolve the issue stop the MCS service on the VDP appliance and start it again .
#dpnctl stop mcs

Once stopped start it again

#dpnctl start mcs

Please follow the KB Could not connect to the requested VDP appliance
