I have a working PowerShell script that sends automated mail when a new user mailbox is created or enabled on exchange server 2013, this works fine except that the images and logos in the html file does not display.

I have read somewhere that you have to add the images as a linked resource.

Anyone know the solution to this?

Thanks. 

I did something like this a while back. Unfortunately, I've forgotten most of it. But ISTR that you have to attach the images, and invent a unique (within the message) content-id property for them, then use that in your <img src="cid:whatever"> .

Or, you might just leave the images on your IIS server, and source them that way.

I used the code below on the script and also edited the HTML document code by changing the imagedata src = cid:xxxx.jpg.

but its still not working. I get an error that "you cannot call a method on a null-valued expression......

$image = New-Object System.Net.Mail.LinkedResource("C:\Welcomemsg\image001.jpg")
$image.ContentId = "image001.jpg"
$image.ContentType = "image/jpg"
$view.LinkedResources.Add($image)

                       

I've never tried this in powershell, so I don't know exactly where to look.  Do you get this error only once you'd added the $image code?  Does it say exactly which line causes the error?  You may need to share the entire script, so that I can try it here.

Edit:

BTW, the reference after <img src="cid: is supposed to match the value for $image.ContentId = .  Apologies if that seems obvious, but in the above code they don't

this is the script i used.....also in the html file the config was imagedata src = cid:image001.jpg for each instance of image.

this is the error i receive

Okay, thanks.  I'm at home now, so I'm not really in a position to try it out.  But I don't see anywhere where the $view in the two occurrences of

$view.LinkedResources.Add($image)

gets assigned to anything.  Should it be

$EMail.LinkedResources.Add($image)

?
