Client using OnPrem Exchange and Windows 2016 Server
I've been asked to look into using Office 365 for them to use
SharePoint
Teams
OneDrive
also Flow, Sway
Looks like they will need O365 Premium
I know I don't need to enable DNS for email i.e mx record etc
what I don't know is how will Team / Flow etc will work in that configuration
Also, currently using a 3rd party email archiving which captures emails before hitting the users mailbox or send queue
Does O365 email archiving work in a similar way ?
