I have an Outlook addin that handles attachments by sending them to our server and then embedding a link into the body of the email containing the URL to the uploaded attachment.
This works but it is not 100% satisfactory because the URLs can get broken depending in the email client and the sender will not see their attachments listed at the top of there email where they are use to seeing them.
Ideally what I would like to do is exactly what is being done for OneDrive.
Currently if I add an attachment and provide a URL as the source it will download the file and send it as a normal attachment which is the exact opposite of what I want. I have noticed that if it fails to download the file it will then just send the URL as an attachment which is what I want. But sending broken URLs is not very useful.
Using
Outlook.MailItem.Attachments.Add("https://myserver.com/somefile", 7, 1, "MyAttachment")
If I set the attachment type to '7' which is what is used for OneDrive attachments I can get it to send the URL but it will first complain about not being able to set some access rights and if the sender clicks OK to continue anyway the attachment will appear to the sender and the receiver as residing on OneDrive which it is not, but clicking the URL will download the file from my server as I want.
My question is: Is it possible to send a none OneDrive URL as an attachment?
(I expect the answer is no, but I am hoping some Outlook guru out there may know some trick to do this.)
My other alternative it to wrap my URLs in an small html file that is then sent as a normal attachment and when opened will provide the link to the actual file.

I'm currently sending reply emails via SMTP using SendGrid to emails I receive. I save the emails I get as .msg and load them as MimeMessage. I add some text as a reply but if the emails have images, the images don't seem to get passed through and I'm not sure exactly where they are. My goal is to send the reply emails with images being retained as currently they show as blank boxes in Outlook saying 'The linked image cannot be displayed. The file may have been moved, renamed, or deleted'.
From my research, I am seeing that images are passed in through attachments and the body of the email show the image as cid:image001.png... . I can't find where the actual images are stored though. When I look into the MimeMessage, attachment is null (unless I attach a file to the email, that file will show but not images within a body of email)
Does anyone have any tips for where to look for the image(s) of emails?
Update: I found the image stored in Body Parts. Will figure out how to pass that one to the reply next.
I managed to export multiple charts as pdf and download it on client side. Is there a way to email that pdf to email that user types. I was not able to find anything. I am using .net framework on server side.
Is it possible to send pdf to server using ajax and to send it to email from server that way?
Assuming that you've got the PDF content and the email address to send it to from the client side, you can send email via .NET from your back-end server. This used to be done via the built-in SmtpClient class but Microsoft now recommends people to use other options like MailKit instead.
You're also going to need an email server to connect to which will handle the delivery of those emails. This could be Gmail if you already have an account or an alternative like SendGrid
As far as getting the PDF content of the chart, Highcharts appears to be taking the SVG content of the chart and using svg2pdf to produce the PDF when not using an export server.
Since there appears to be no (documented) way of exporting to anything other than a file, you're likely going to need to mimic this process yourself by taking the SVG content via chart.getSVG() and then using svg2pdf to get your PDF content to send to your server.
Highcharts is a client html2print generator and like jsPDF or other client based solutions the PDF generation is per user selection of PDF printout options. (The client has control over PDF so no need for them to email it to self or others, unless they have to.)
Per link above
However, for situations where you may be generating a report for a client who has just seen the screen (and you don't need to change the chart in anyway) - why would you want to render the chart server side? when the client has already done the work.
To build server side automatically using a browser the server needs generally to process it, just like a user, with say chrome --headless options for html2pdf (and chrome can normally do that in one line, but with limited user layout options).
At that point you could have a PDF for attachment by any conventional mime application/pdf means (e.g. convert to base64.txt).
However due to the more dynamic drawing of svg (rather than a static insert) I could not run an Out.PDF --headless just by CLI, so it would need a driven solution such as selenium/puppeteer. THUS you may need to follow the suggestions in the lee-m above answer to build and modify the svg output.
for me I was able to run printEdge.vbs (with my current landscape defaults)
DIM shell
SET shell = WScript.CreateObject("WScript.Shell")
Shell.Run "cmd /c start msedge.exe file:///C:/Users/WDAGUtilityAccount/Documents/highchart.htm"
WScript.Sleep(4000)
Shell.SendKeys "^p"
WScript.Sleep(3000)
Shell.SendKeys "{enter}"
WScript.Sleep(1000)
Shell.SendKeys "{enter}"
WScript.Sleep(1000)
Shell.SendKeys "y"
WScript.Sleep(1000)
Shell.SendKeys "{esc}"
WScript.Sleep(1000)
Shell.SendKeys "%{f4}"
I would like to know if it is possible to open and reply as a response message on top of a saved .eml file using C#?
If yes, are there any guides that I can follow?
I am able to do so with EWS EmailMessage where the message resides in Inbox. However, due to requirements, I am required to retrieve and reply from a saved .eml file instead of replying from the email in Inbox directly.
Thank you.
No you can't do this using the EWS reply operations because EWS is a Server side API while using the EWS Managed API you using Client side library that just instrumenting the SOAP call to the backend whenever an action is taken. You can temporary import the EML back in the server https://learn.microsoft.com/en-us/exchange/client-developer/exchange-web-services/how-to-import-items-by-using-ews-in-exchange and then you reply and then delete the Message again if don't want it to exist. If your want to send using EWS you didn't want to import the message use something like mimekit to generate the MIME of the response message offline http://www.mimekit.net/docs/html/Frequently-Asked-Questions.htm then you can just sent the Mime generated by mimekit via EWS.
In theory you could achieve this, by first opening the EML file (please see this question and answer):
Retrieve Email Information from .EML Files
And then when you have the contents of the message in code, copy the data over to whatever email-sending API you are using.
Step 1:-
Click the message options menu in the top right corner of the message. Select Save email.
Step 2:-
Save the file. The file name will default to the subject line of the email, with special characters removed. Your download options depend on whether you're using Front on the web or in the desktop app:
*Web: Your file automatically saves to wherever you have it set up in your browser settings (like your Downloads folder)
*Desktop app: You will get the “Save As” prompt where you can rename the file and choose your download location
Step 3:-
You will see your .eml file in your chosen location. You can attach it to a message via drag-and-drop or with the attachment file picker.
I'm trying to download an InfoPath template that's hosted on SharePoint. If I hit the url in internet explorer it asks me where to save it and I get the correct file on my disk. If I try to do this programmatically with WebClient or HttpWebRequest then I get HTML back instead.
How can I make my request so that the web server returns the actual xsn file and doesn't try to render it in html. If internet explorer can do this then it's logical to think that I can too.
I've tried setting the Accept property of the request to application/x-microsoft-InfoPathFormTemplate but that hasn't helped. It was a shot in the dark.
I'd suggest using Fiddler or WireShark, to see exactly how IE is sending the request, then duplicating that.
Have you tried spoofing Internet Explorer's User-Agent?
There is a HTTP response header that makes a HTTP user agent download a file instead of trying to display it:
Content-Disposition: attachment; filename=paper.doc
I understand that you may not have access to the server, but this is one straight-forward way to do this if you can access the server scripts.
See the HTTP/1.1 specification and/or say, Google, for more details on the header.
This is vb.net, but you should get the point. I've done this with an .aspx page that you pass the filename into, then return the content type of the file and add a header to make it an attachment, which prompts the browser to treat it as such.
Response.AddHeader("Content-Disposition", "attachment;filename=filename.xsn")
Response.ContentType = "application/x-microsoft-InfoPathFormTemplate"
Response.WriteFile(FilePath) ''//Where FilePath is... the path to your file ;)
Response.Flush()
Response.End()
I'm using SubVersion and TRAC on a C# project I am working on, and I have my TRAC system setup with a email address that can be used to create tickets. In my program I've added a simple "FeedBack" button in my program which sends an email to this address. To open the email I'm just "starting" a mailto link as shown below.
System.Reflection.Assembly assem = System.Reflection.Assembly.GetExecutingAssembly();
string ver = assem.GetName().Version.ToString();
System.Diagnostics.Process.Start("mailto:foo#bar.com?subject=<Provide a title for your feedback here>&body=< Describe the problem you are having or enhancement you would like to suggest here. Please be as descriptive as you can, and if possible list out the actions that will replicate the problem >%0D%0A%0D%0A%0D%0AVersion: "+ver);
The problem I'm running into is if the user is using Outlook and their copy of Outlook is setup to HTML the ticket that gets created ends up having a bunch of HTML code that I have to clean up. Is there some way to notify whatever mail client is handling it to send the email as text rather then HTML?
There's nothing you can do (besides education) on the client - there's nothing in mailto to control a client side program. And, frankly, with the proliferation of web-based email - I think mailto is showing it's age.
Outlook should send a mime/multipart message, with both plain text and HTML parts. I'd guess you could extend or patch Trac to only grab the text/plain portion.
Otherwise, just create a form in your app to capture the email info. Again, if someone is using Hotmail or GMail - mailto is not likely to work anyway (or will open up their unconfigured Outlook Express, where they will dutifully type up an email and press Send. Only it won't go anywhere, because no SMTP servers are configured - so it will languish in the Outbox for years. Not that they will notice though...).
