Can apple mail on iOS be used to configure server-side rules on exchange server
When using an Exchange mailbox, Exchange supports server-side rules to filter and sort mails automatically. This works on the server, so the client does not have to be online.
Those rules can be configured with Outlook and with Outlook Web Access, but can they also be managed used Apple Mail for Exchange mailboxes?
No, it cannot.
But if you have access to an Exchange mailbox from Apple Mail, these days the chances are close to certainty that you'd have Outlook Web Access in some form, and from there, you can set server-side rules.
