By Impran M N
Switching between separate mail profiles all day is a productivity drain, especially when time-sensitive messages land in a secondary account. This guide covers pinning multiple inboxes to your Favorites, turning on the new Outlook's unified All Inboxes view, and opening a side-by-side window for full multitasking.
01Open the folder sidebar
Launch Outlook and locate the folder navigation sidebar pane.
02Pin inboxes to Favorites
Drag separate inbox folders into the top Favorites section for quick toggling between accounts.
03Enable All Inboxes
In the new Outlook, turn on the integrated All Inboxes shared view to merge separate streams into one chronological feed.
04Open a side-by-side window
Right-click an inbox and select Open in New Window to view multiple accounts across separate monitors.
05Build a unified search folder
Create an All-Account Search Folder to automatically aggregate unread messages from every connected account.
06Save your layout
Save your customized view settings globally so your layout persists across sessions.
Frequently asked questions
Does the All Inboxes view combine every connected account?
Yes, it's designed to merge separate account streams into a single chronological feed within the new Outlook interface.
Can I still tell which account a message came from in the unified view?
Unified views typically retain account labeling so you can identify the source even when messages are combined.
Is opening a new window better than the unified view for multitasking?
Opening a separate window works well if you have multiple monitors and want dedicated, full-size views per account.
Will my Favorites setup carry over if I switch computers?
Since Favorites and view settings are typically saved with your profile, they should carry over when you sign in elsewhere, though this can vary by setup.
