I am just about to transfer my emails over to Zoho, but can you clarify for me the options for archiving please ?

1) if I choose to archive mail, does it still count towards my data quota of my plan ?

2) Can mail be taken off as a .pst file so that I can be sure I have a backed up archive of my mail always as this is how I have always managed the email before ?

3) Where can I find out on your site what your security of email is in Zoho ?

Thank look forward to hearing from you

Mary
