The Microsoft Teams desktop app for Windows and Mac already supports multiple accounts: you can sign in to several work, school, and personal accounts, plus organizations where you're a guest, switch between them, and get notifications from all of them. Teams on the web is more limited and works best with one account at a time.
WebCatalog Desktop fits when you prefer the web version and want each tenant signed in separately, in its own window, next to that tenant's Outlook and SharePoint.
Add accounts in the Teams desktop app
Microsoft's guide to managing accounts and organizations covers the steps:
- Select your profile picture at the top of Teams.
- Choose Add another account.
- Pick an account you've used before, or choose Create or use another account and sign in.
To switch, select your profile picture again and choose another account or organization. You can pin up to three accounts to the sidebar and move between them with Switch. Organizations where you're a guest appear automatically, so you don't need to add them as separate accounts.
To get alerts from accounts you're not currently viewing, open Settings and more > Settings > Accounts and orgs and turn on notifications for each one. In the Activity tab, Activity in your other accounts and orgs shows what you missed elsewhere and opens it in a new window without switching your main account.
Teams on the web
Teams on the web runs in Edge, Chrome, Firefox, and Safari on a desktop computer, and you can switch accounts from your profile picture. According to Microsoft's Teams for Web overview, though, it doesn't offer simultaneous availability and notifications across multiple accounts and tenants. To stay signed in to two tenants in a browser, you'd need a separate browser profile for each.
Group each tenant's apps with WebCatalog Desktop
If you work across several Microsoft 365 tenants, for example your employer and a client that issued you its own account, WebCatalog Desktop can keep them apart. It runs Teams' web version as its own desktop app, with a separate window and Dock or taskbar icon.
Profiles keep cookies, sessions, and browsing data separate, so each tenant stays signed in on its own. To set one up:
- Open WebCatalog Desktop and go to Profiles.
- Choose Add profile and name it after the tenant, such as "Contoso" or "Client A."
- Open Teams with that profile and sign in with that tenant's account.
- Repeat for each other tenant.
Because one profile can be reused across apps, the same "Client A" profile can sign in to that client's Outlook and SharePoint too. Spaces then group those apps, so each client's Teams, mail, and files open together in one window. The full steps are in the profiles help article.
One limitation: this uses Teams on the web, which lacks some desktop features, such as pop-out chat windows, avatars, and most video background effects. If you rely on those in meetings, use the Teams desktop app for meetings.
FAQ
Do I need to add an account for every organization I'm a guest in?
No. Guest organizations linked to your account appear automatically, and notifications from them are on by default. You only need another account, or another WebCatalog Desktop profile, for a separate sign-in.
Conclusion
If the Teams desktop app's account switcher covers your work, use it. If you'd rather keep each tenant's Teams, Outlook, and SharePoint together in their own window, download WebCatalog Desktop.
