I use zimbra 8 and I would like to ask 2 questions:
1) Now all user have default composing in text format. Is there a way how to change easily so that all users have default composing in html? (I do not want to go through all account to change it individually)

2) If I as an administrator want to create a signature in administrator console I can create only a text version of the signature. Is there a way to create it in html version under administrator console?

Thank you for help
