CONNECTING DOMAIN
Hi
I work for a small not for profit organisation new to Microsoft 365 (and have no experience with it or even IT in general ). We have 10 licences which have been assigned to our staff and executive committee but have not connected our existing domain as there is a warning about making sure everyone's setup with their email address otherwise they wont be able to access it. Our problem is we have more than 10 people with existing emails although we do not need them all set up in microsoft 365. If I connect our domain, does that mean everyone can only access their email by signing in with a microsoft 365 sign in? ie only those we've assigned a licence to will be able to access their email? Can those not assigned a licence still access their existing email? Thank you...
