just finalizing migration to 2013 and having hard time finding where to configure in ECP to disable mailbox features like IMAP, POP3, OWA for all users as a default.

appreciate any help.

Hello

tip:

get-mailbox -resultsize unlimited | Set-CASMailbox -PopEnabled $false -ImapEnabled $false -OWAEnabled $false

or disable imap and pop service

hi,

i was thinking something like that would affect only future mailbox creations.
