I am new to C# & MVC but have written a simple web application which updates a users Outlook Email Signature.
This application works in my test environment but when I deploy I receive errors around the Word Interop assembly I'm using.
I have seen blogs which discuss why you don't want to install and use server side Office applications. How can I use the office installation on the executing user's computer?
It is safe to assume that all users navigating to this application will have office installed on their machine.
How can I create a word file locally on their machine from an MVC Web app which is a simple form? Is my only option OpenOffice XML?
I'm sorry if this question isn't well structured, I'm struggling to understand the concept myself
Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment.
If you are building a solution that runs in a server-side context, you should try to use components that have been made safe for unattended execution. Or, you should try to find alternatives that allow at least part of the code to run client-side. If you use an Office application from a server-side solution, the application will lack many of the necessary capabilities to run successfully. Additionally, you will be taking risks with the stability of your overall solution. Read more about that in the Considerations for server-side Automation of Office article.
As a workaround you may consider using any third-party components designed for the server-side execution or just Open XML SDK, see Welcome to the Open XML SDK 2.5 for Office for more information.

Hi I have created windows service c# to create an excel file. When I scheduled and running under my id in dev environment it is working fine. But when i run the same service with different interactive Id which is also an administrator account in the server, the service is failing at the line Excel.WORKBOOK.saveas(object) with the below error
"Microsoft Excel cannot open or save any more documents because there is not enough available memory or disk space." I have tried many solutions provided in net to provide permissions in comconfig and to create desktop folders in c:\windows\sys32 and syswow64.
But still unable to find it.. only with my id the service is running fine but any other interactive if it is failing. Please help

I am getting the below error when I try to access Outlook folder to download an attachment from my inbox.
My code working perfectly when I run from Windows Form application. But when I use Windows Service to auto scan the Outlook folder, I am getting this issue.

As a workaround you may consider using a low-level API on which Outlook is built - Extended MAPI or any other third-party wrapper around that API (such as Redemption).
We are trying to open a Word template which resides on a Shared Drive using Office Interop Services on an MVC application.The solution is working locally, but once is deployed to the server the following message appears:
The File was not created: System.Runtime.InteropServices.COMException (0x800A1436): This file could not be found
ApplicationPool is running under a domain user account which already has permissions on the shared drive.
Any suggestion?
You may consider using the Open XML SDK for dealing with open XML documents (.docx), see Welcome to the Open XML SDK 2.5 for Office. Or any other third-party components designed for the server-sider execution (for example, Aspose).
