When Using Office 365 (Home or Business), did you know you can set up multiple Microsoft accounts to be available to you when working on and saving documents?
What do I mean by this? Well, for those of us using either Office 365 consumer or O365 Business, we know that we should get our apps set up by signing into our Microsoft account when first getting set up.
For example, open up Word and click ‘File’ to get to the backstage view, then scroll down to ‘Account’ and click on it. If you’ve never signed up, you will most likely get a prompt to do so. If you’re at work, you’ll enter in your business O365 credentials. If you’re using O365 Home, you can enter in one of your Microsoft accounts.
You see in the illustration that I’m signed into a Microsoft account. But look below that and you can see I’ve connected my O365 Business account as well. So I’m using multiple accounts – efficient!
Video of How To Add Your Microsoft Accounts
I did a short video to show you how to sign in and personalize your Microsoft Office desktop apps experience.
I also did a SlideShare you can look at or download that highlights the top things to do once you buy Office 365.
Office 365 Business Accounts
Now if you’re at work, you probably won’t want to connect any personal accounts, just your business O365 account.
After you’ve signed in with your business credentials, you’ll want to connect, or add-in both your SharePoint sites and your ODB (OneDrive for Business). You do this in the backstage view – look for connected services at the bottom (see illustration above).
Office 365 Personal Accounts
If you have Office 365 Home (the $99/year subscription service), you’ll be able to add multiple Microsoft accounts to your desktop apps (Word, Excel, PowerPoint).
For my situation, I work from home, so I don’t mind having both my business O365 and personal O365 accounts all together on one computer. On this work station, I have 3 accounts and I can switch among them if I wish. 
However, I really don’t need to because I’m able to save my documents into either my ODB, SharePoint or OneDrive consumer since I’ve connected all these services on my computer.
When I do a ‘Save As’ command, you’ll see I’m presented with three OneDrive or SharePoint choices. I can also choose to save to the local drive (Computer) if I wish.
This gives users a way and choice to put documents in the storage of their choosing.
Choose What’s Best for You
I hope this was helpful and perhaps gives you some ideas to make your own work flow more convenient and productive.
