I am using Send Grid to send Emails in .NET Core API , send grid is behaving weirdly by replacing spaces with Question marks when email lands in user inbox .This is how my HTML looks like when I open it in debug mode at backend.
But I receive email like this in my inbox.
This is only happening with my organization based outlook accounts , it works fine on @outlook and @gmail
The HTML that is being generated is same for @gmail and organization office account , problem is with browser I think
