If you have multiple Microsoft accounts for work and personal use-cases and you also utilize Microsoft 365 apps such as Excel, Word, PowerPoint, OneDrive, Outlook, and more on the web, then your online life is about to become a lot easier, thanks to Microsoft.
Up until now, it has only been possible to sign in to a single Microsoft account in a browser at one time. If you want to use another account instead, you first have to sign out from your current account and then log in to the other one. It's an archaic user experience that seems more like a chore if you utilize multiple personal and work accounts in the same browser instance.
Of course, there are workarounds where you can create separate profiles in a browser, use different browsers to segregate your workflows, or just not do personal stuff on a work machine, and vice versa.
However, sometimes this need is unavoidable and up until now, Microsoft forced you to sign out of one account in order to log in to another. This is changing soon as can be seen in an entry with Feature ID 70801 on the Microsoft 365 Roadmap. It basically says:
Users can sign into multiple work and personal accounts on Microsoft 365 web apps in the same browser. This also allows them to seamlessly switch between the accounts without having to sign out and sign back in again.
Well, there you have it folks, Microsoft has finally seen the error of its ways. The company will be facilitating you in utilizing multiple Microsoft 365 accounts without making the process a headache.
The feature was added to the Microsoft 365 Roadmap today and the target release date for general availability is April 2022, which can't come soon enough for yours truly.
