I have been successfully using the stock e-mail app to connect to my work exchange server ever since being upgraded to 2.2. For some reason, not until this most recent update to 2.2.1 could I get my signature to work properly, but even now the signature only appends to "new" messages I send. I have not been able to get it to append to e-mails I reply to or forward. I also could not find anything that calls this out specifically in the Android 2.2 users guide. Is there a setting I am not finding that will allow my signature to be appended to replied and forwarded e-mails? (for exchange email, not gmail) Thanks for any pointers/help anybody can offer.
