OutlookBuddy von Banjac

Juggling several Outlook / Microsoft 365 work accounts in the browser is painful: open two at once and they log each other out, and switching means signing in and picking an account every time.

OutlookBuddy fixes that. Each account lives in its own isolated Firefox container, so every account stays permanently signed in - independently. Add your accounts once, then:

• Click any account in the toolbar popup to jump straight to its inbox.
• Cycle between mailboxes instantly with Option + Page Up / Page Down.
• No logouts. No "switch account" prompts. No re-typing passwords.

Works with any Outlook / Microsoft 365 web address, and you can point an account at any other site too (Gmail, Teams, etc.).

Private by design: your account list is stored only in your own browser. OutlookBuddy collects nothing, sends nothing, and has no servers.
