How to read encrypted email send from Outlook 365 to an outlook email address

Question

I received an encrypted email in outlook probably from someone with Microsoft 365. I do not have Microsoft 365. According to https://support.microsoft.com/en-gb/office/send-view-and-reply-to-encrypted-messages-in-outlook-for-pc-eaa43495-9bbb-4fca-922a-df90dee51980 I should be able to decrypt this message through a link in the email. But the email only shows me "You don't have sufficient permissions to open the mail." when opened in either webmail or through the android Outlook app.

Is there any way to open these emails?

(Outlook support told me no. That I need a Outlook 365 account and use the desktop app in order to be able to open these emails. This directly contradicts their own documentation so it seems they are not well informed themselves.)

Answer 1

Support explains that, without access to Windows, decryption works for any email address EXCEPT outlook/hotmail ones. For these the link will not appear (as they assume you use the windows desktop application). Note that the outlook web email or android app do not support decryption either. Since I don't have a Windows device there is absolutely no way to open these emails.

So I guess in doing this Microsoft is teaching a valuable lessons never to use their products as even they themselves put compatibility with other email providers as a higher priority then support for the email addresses they themselves provide.
