Outlook VSTO Add-In - Block attachments via file extensions

Hi there! I am a software developer with experience working with Outlook VSTO Add-in's. This functionality can be built using this type of addin, it will have an option in a custom tab where you can select the extensions allowed/forbidden to be attached. When the user tries to select a file to attach with an extension that is not allowed, an error message will alert the user about it and the file will not be attached. I can deliver the plugin with an .exe installer package in a couple of days. Looking forward to working with you.

Hi Sir/Madam, I have been working with Office development for 8 years. I have experience with Office addin/plugin. I developed many addin/plugin for Outlook, Excel, Project, Word as application based or document based like work item management(outlook), project document management(outlook), task health checker(project), invoice management(excel), article integration with inhouse application(word). I used the Sharepoint, SQL, One drive as datasource. You can check my freelancer profile to see some plugins. Please let me know if you have any questions.

Ptoject is ready. in setting box just check extension type like .pdf, .XML, doc etc and save now when you try to upload these extensions file alert message will come and it will not get attached .

hey I m Vinayak Varshney, i will do this job with full dedication . I really want to do this job, I am very passionate and will never disappoint to you.
