How to configure Office 365 without disrupting Shopify transaction emails?

Hi all,

For one of our clients we need to configure their Office 365 account. Shopify manages their primary domain. Before i fully configure the domain settings within the Office 365 Admin, i need to make sure transaction email from the Shopify shop is not disrupted.

At the moment, the Shopify DNS settings contain several email related records, like:

mx.[client URL].com.cust.b.hostedemail.com	
b446fd2c1252.p570.email.myshopify.com	

And several DKIM records from Shopify.

As far as i know, there can only be one MX records and it needs to be the Microsoft one:

[client URL]01cb.mail.protection.outlook.com.

If i replace the original Shopify MX records with these Microsoft/Office 365 records, will transactional e-mail be disrupted? Or can these MX records co-exist?

Same goes for the SPF and DKIM records: I need to add a SPF record for Microsoft, but in my experience Shopify should also be added to this record to conform valid usage of the domain.

Thanks in advance for any help!
