Change Default Mailbox Login/Auth Methods

[andrewvinci]

The default settings for mailbox access includes login via pop/imap. I can turn off individual mailboxes, however would like to change the default settings to disable pop/imap.

Can this be done through an admin center? or is it only possible via powershell?

Thanks Steve,

Bit strange this is enabled by default, with no UI to change it! Is pop/imap not considered a valid attack surface anymore?

haven't checked in a while what is now default on new tenants when provisioned - we just have it as a standard playbook item to disable them :)
