I would like to write a small script to create a csv file with the mailbox fullname, size limit, and the actual mailbox size. I already have a working solution, but it is slow. It takes about 2 minutes to create such a csv with 300 mailboxes. There is an option on the gwadmin webservice to list the current mailbox size together with the username, domain, etc. and it displays this info much faster than my script. Do you know a fast way to collect the mailbox name, fullname, email address, boxSizeLimit and mailboxSize via REST API?
