Environment

This article applies to Bowdoin faculty and staff who have the Microsoft 365 desktop apps installed and who sign in with a Bowdoin account. Microsoft documents the Teams default-app setting as available on Windows with a qualified Microsoft 365 subscription, and the setting is not offered in Teams on the web.

  • Bowdoin-issued Windows 11 computers and Bowdoin-issued Macs running macOS Sequoia (15.x), Tahoe (26.x), or newer are supported. Personally owned computers are best-effort only.
  • Sign in to Microsoft 365 at https://office365.bowdoin.edu before opening files stored in Microsoft Teams.
  • Opening a file in a desktop app from a Microsoft SharePoint or OneDrive library requires the OneDrive sync app installed and running, Files On-Demand turned on, and Office signed in with your Bowdoin work or school account.
  • Opening a single file in a desktop app works on both Windows 11 and macOS. The Teams setting that changes the default for every file is a Windows feature.
  • Reading and editing Teams files on iPadOS (current version) happens in the Microsoft Teams and Office mobile apps, which do not offer these settings.
  • Deciding between an OneDrive shortcut and a full sync is not covered here. For that decision, see Choose How Teams and Shared Files Appear on Your Computer in the Related Articles section.

Resolution

Set the Word, Excel, and PowerPoint desktop apps as the Teams default

Changing the Teams default once sends every Word, Excel, and PowerPoint file opened from Microsoft Teams to the installed desktop app.

  1. In Microsoft Teams, select Settings and more (…), then select Settings.
  2. Select Files and links.
  3. Under "Always open Word, PowerPoint, and Excel files in", select Desktop App.

The other choices in the same setting are Teams, which opens a file inside Microsoft Teams without switching apps, and Browser. When Desktop App is not offered at all, you are working in Teams on the web or on a platform where the setting is unavailable, and opening files one at a time is the way to reach the desktop app.

Note: Microsoft offers the "Always open Word, PowerPoint, and Excel files in" setting on Windows 11 with a qualified Microsoft 365 subscription. On a Mac, open each file in the desktop app individually, or add the channel as a shortcut in OneDrive so files open from Finder.

Open a single file in the desktop app without changing the default

From the Microsoft Teams app

Right-click the file in the channel and select Open in, then choose the desktop app. Opening one file this way leaves the Teams default setting exactly as it was.

From a SharePoint or OneDrive library in a browser

  1. Select the file.
  2. Select More (…).
  3. Select Open, then select Open in app.

Open Teams files from File Explorer or Finder

Adding a Teams channel as a shortcut in OneDrive makes the channel's files appear in Windows File Explorer or macOS Finder, and double-clicking a file there opens the desktop app directly. A shortcut is the recommended default for getting Teams files onto a computer, and syncing is reserved for specific cases. For the steps to add one, see Add a Shortcut to a Teams Channel or Shared Folder in OneDrive in the Related Articles section. To compare a shortcut with a full sync, see Choose How Teams and Shared Files Appear on Your Computer in the Related Articles section.

When the browser version of Word, Excel, or PowerPoint is the better choice

The web versions of Word, Excel, and PowerPoint are not a lesser option. A browser is the better choice in these situations:

  • You are making a quick edit. A file opens in a browser faster than a desktop app starts.
  • Someone else is editing the same file at the same moment. Changes made by other people appear more promptly in a browser.
  • You are working on a computer that has no Microsoft 365 desktop apps installed, or on a computer that is not yours.
  • A desktop app is behaving oddly. Opening the same file in a browser shows whether the problem is the file or the app.

Choose the desktop app for features a browser does not have, for large or complex files, and for work without an internet connection. For keeping Teams files available with no connection, see Work with Teams Files Offline in the Related Articles section.

When the desktop app opens a read-only copy

A read-only copy is almost always a permission problem or a lock rather than a fault in the app. Check these four causes in order.

  1. You have view-only access. Ask a Team owner to give you edit access to the channel or the folder that holds the file.
  2. Someone has the file checked out, or an app is holding the file open. For how to identify and clear a lock, see When a File Is Locked or Open Somewhere Else in the Related Articles section.
  3. The file was marked as final. A file marked as final has to be unmarked before anyone can change it.
  4. You opened a downloaded copy. A file sitting in your Downloads folder is a detached copy with no connection back to the channel. Close the downloaded copy and open the file from Microsoft Teams instead, or your edits will never reach anyone else.

Sign in to Office with your Bowdoin account so edits save back to Teams

The Microsoft 365 desktop apps save changes back to Microsoft Teams only while they are signed in with your Bowdoin account. When Office is not signed in, or is signed in with a personal account, Word, Excel, and PowerPoint prompt you to save the file somewhere else and the edits stay on the local disk.

  1. In Word, Excel, or PowerPoint, select File, then select Account.
  2. Confirm that your Bowdoin address is listed as the signed-in account.
  3. If your OneDrive is not listed under connected services, select Add a Service, then Storage, then add OneDrive.
With Office signed in as your Bowdoin account, AutoSave turns on for files stored in Microsoft Teams, SharePoint, and OneDrive, and your changes save as you work.
