带有数字签名的电子邮件上的Outlook加载项 [英] Outlook add-ins on emails with digital signatures

问题描述

大家好，

我开发了提交合理的请求

<最后，我坚信，而不是允许"只读"。访问这些消息，Microsoft只是完全限制对它们的访问。他们是否有任何计划实施这样的事情你可能应该通过用户语音网站
询问。作为"伙伴"如果你需要，你应该有权提交该功能的内部请求。

希望这有帮助，

Hi everybody,

I develop Keluro, an add-in for Outlook to help industries managing their emails.

The add-in works fine on Outlook desktop or OWA however, it can't be opened for emails with digital signatures (ones with the small red ribbon, see picture below).



It seems that all add-ins are disabled with this kind of emails. Am I right? If so do you know the reason and if Microsoft plans to deploy the add-ins also for these emails?

Thanks,

Gregoire

Hello Gregorie,

I have verified your scenario with both signed and signed & encrypted messages. The following are results ...

1. The add-ins are not working for those type of the message in preview panel. More likely based on context type of the message, because the message class is still the same IPM.Note. By clicking on an add-in the following error message displayed:

2. When message open in new inspector (double click on the message) the add-ins are disabled.

So, I hope the fact is confirmed and you are right, add-ins are not working with those types mail items. The reason the add-ins are not working with those types of items is very simple. Those items are signed by the sender and if Microsoft allow to manipulate with parts of those messages the signature will be invalidated and verification will fail. Those are the message which you cannot temper with. You may say that you want to use the message in kinda "read only" mode, so Office.JS API will work to get info, but never set anything back. It would be reasonable request which you may submit to Office Developer Platform UserVoice page

And finally, I strongly believe, instead of allow "read only" access to those messages, Microsoft just restricted access to them completely. Do they have any plans to implement something like this you probably should ask through User Voice website as well. As the "partner" you should have access to submit internal request for the feature if you need as well.

Hope this helps,
