Exchange 2010 - Email signature setup with Transport Rule - Want to disable the rule for iOS devices
So we decided to have a company wide email signature which pulls user info from AD to fill in the HTML template. What I have found out is that iOS devices send email as plain text which displays the HTML content with strings of text in emails send from those devices. The only way I have found to make this work is have the user keep the default "Send from my iPhone" signature and exclude the rule based on that text in the body. Is there a cleaner option in case our users decide to change their default signature on their iOS devices?
I can't find a clean answer for you.
You might use the Set-TransportRule cmdlet and one of the exception clauses to look for something in the header. I looked at an ActiveSync-generated header from my Droid (I don't have an iPhone to try this out on) and I see this:
should exclude messages sent from Droids. Of course, I can't say that it'll exclude all of them so you'll have to experiment and use trial and error.
You may need to experiment with the rule because I haven't tested it.
