Open Microsoft 365 links in your work account, every time

Junction is a free, open-source macOS app that becomes your default browser and routes each link by your rules. For Microsoft 365, that means company SharePoint, OneDrive, and Outlook links open in the Edge profile signed in to your work account, instead of whichever browser happens to be the default.

How do I open SharePoint and Outlook links in Edge?

Write a rule that matches your company’s Microsoft 365 hosts and opens them in Edge. Edge’s bundle ID is com.microsoft.edgemac.

{
  "name": "Microsoft 365 → Edge",
  "match": { "patterns": ["*.sharepoint.com/*", "outlook.office.com/*"] },
  "action": { "app": "com.microsoft.edgemac" }
}

$ junction test "https://contoso.sharepoint.com/sites/finance"
input:       https://contoso.sharepoint.com/sites/finance
rule:        [1] Microsoft 365 → Edge
action:      open in com.microsoft.edgemac
url:         https://contoso.sharepoint.com/sites/finance

*.sharepoint.com/* covers every company’s SharePoint site and its OneDrive, which lives on a -my.sharepoint.com subdomain.

How do I open them in my work Edge profile?

Add a profile with the profile’s directory name. Edge stores profiles the way Chrome does: Default for the first, then Profile 1, Profile 2, and so on. Settings → Browsers lists each Edge profile with its directory, once Junction has Full Disk Access.

{
  "name": "Contoso 365 → Edge work profile",
  "match": { "patterns": ["contoso.sharepoint.com/*", "contoso-my.sharepoint.com/*", "outlook.office.com/*"] },
  "action": { "app": "com.microsoft.edgemac", "profile": "Profile 1" }
}

Naming your own tenant (contoso) instead of *.sharepoint.com keeps other companies’ shared links out of your work profile.

Can personal Microsoft links go somewhere else?

Yes. Personal Outlook and OneDrive use different hosts from work accounts, so a second rule can send them to another profile or browser.

{
  "name": "Personal Microsoft → Edge Default",
  "match": { "patterns": ["outlook.live.com/*", "onedrive.live.com/*"] },
  "action": { "app": "com.microsoft.edgemac", "profile": "Default" }
}

Can Teams links open in the Teams app?

Yes — that’s a deep link rather than a browser rule. See Zoom and Teams links.

Does this work with Chrome instead of Edge?

Yes. Swap the bundle ID for com.google.Chrome; profiles work the same way. See Chrome profiles.
