I'm trying to add a HTML signature but I keep getting an error saying my signature is above 1024 characters.

I've then deleted most of the signature and I still get the error.

I wanted to move over to Zimbra from outlook but this is the only thing holding me back, every other client will allow my signature.

I've searched around the forums and found loads of posts about this one mentioned editing a bunch of files .. but I'm not technically minded enough for it really.

I have tried editing the attrs xml file which has the SignatureMax part in it, but each time I get a message saying access has been denied .. I'm logged in as an administrator on my PC ahh.

Any ideas?
