Office 365 Firewall Rules

RouterOS General
1

Hi,
i have one VLAN which has no access to Internet and has access only to few IP’s from internal network.
Rules are like:
SRC ADDRESS=[IP form VLAN] DST ADDRESS=[Server IP] CHAIN=Forward ACTION=Accept
SRC ADDRESS=[IP from VLAN] DST ADDRESS=0.0.0.0/0 CHAIN=Forward ACTION=Drop

Now i need to provide access for this SRC ADDRESS to Office 365 (Outlook mailbox).

How can i do this?

You can create an address list named office365 and add the domain name(s) required to access the service.
Then you can add an extra allow rule with that address list as a dst.address list.
It works best/only when you force the clients to use the builtin DNS service of the router as well.
