This question already has an answer here:

We have recently started using Office 365 for our email, which requires us to add a DNS TXT record with the value v=spf1 include:spf.protection.outlook.com -all. We already have an SPF record with the value v=spf1 include:spf.mandrillapp.com ?all for Mandrill, an SMTP sender we also use.

enter image description here

My concern is this might cause some conflict. Is my concern valid or will be be fine with these two SPF records?

You can only have one SPF record.
You need to combine them like so:

v=spf1 include:spf.mandrillapp.com include:spf.protection.outlook.com -all


v=spf1 include:spf.mandrillapp.com include:spf.protection.outlook.com ?all
