Apple mail and Microsoft outlook running on same MacBook

Let me try to clarify the part that seems to be misunderstood.

You can have both Mail and Outlook open at the same time, and each handling different accounts, as you said you wanted to do. It should work fine.

The only “restriction” that I alluded to is this: suppose you are visiting a website and it has a link that says “Contact us”, and that link is to open an e-mail message addressed to the holders of the site. When you click, an e-mail program opens - which one? The one that you set as the default.

There is nothing stopping you from doing just what you asked, AFAICT.

You add your e-mail accounts as usual, in System Preferences->Internet Accounts.

In Mail, you can make “inactive” the work accounts, so ut only checks the mail for your personal ones.

I don’t use Outlook but I imagine it can do something similar.

Note: there is only one “default” mail application. This is tge application that will open if you click on a link that is to send mail. But this does not affect using both for checking mail, replying, etc

You set the default mail application in Mail->Preferences->General.

You can run as many email clients as you like at the same time. Just configure each with the email account(s) you want to use with that client. You can only have one of the email clients configured as your default email client. So if you click on an email link in a web page or whatever, the default email client will open. You can use whatever email client you want on each device.

Not a problem. You will not configure the same email accounts on both email clients. They will not be accessing the same account at the same time. And even if they did, servers can handle that through queuing etc.

So your question is different from that of the original poster. It is better to post a new, separate question when you are asking about something different.

That said, yes, if you run Apple Mail and MS-Outlook both on the same Mac and both using the same email account, each will keep its own data base with all the same emails, which means you will basically double the space needed on your Mac for the same email messages. I once did this as an experiment. It does work, and the storage taken is about double. Not exactly double because Apple and Microsoft store the emails and attachments differently. But yes, basically double.

I didn’t say you can’t run both at the same time. You CAN.
