Solution

1. Step 1: Identify storage needed for co-authoring

   Co-authoring requires cloud storage to sync changes live, like OneDrive or SharePoint.

   Local desktop saving or offline mode won't sync live changes; disabling AutoSave stops live updates.

3. Final Answer:

   Save the file in OneDrive or SharePoint -> Option C

4. Quick Check:

   Cloud storage needed = Save the file in OneDrive or SharePoint [OK]

Hint: Co-authoring needs cloud storage like OneDrive [OK]

A. The file will create two separate copies for each user.

B. Only the first user can save changes; the second gets an error.

C. Changes are saved only after both users close the file.

D. Both users see each other's changes live without conflicts.

Solution

1. Step 1: Understand live co-authoring behavior

   When editing different cells, Excel syncs changes live so both users see updates immediately.

2. Step 2: Eliminate incorrect options

   Creating separate copies, blocking the second user from saving, or delaying changes until closing do not happen with real-time co-authoring.

3. Final Answer:

   Both users see each other's changes live without conflicts. -> Option D

4. Quick Check:

   Live sync = Both users see each other's changes live without conflicts [OK]

Hint: Different cells update live for all users [OK]

Common Mistakes:

• Assuming only one user can save
• Thinking file duplicates automatically
• Believing changes save only on close

You and a colleague are co-authoring an Excel file, but your colleague's changes are not appearing live. What is the most likely cause?

medium

A. You are using Excel Online.

B. The file is not saved in OneDrive or SharePoint.

C. You are both editing different cells.

D. You both have AutoSave turned on.

Solution

1. Step 1: Check storage location for live updates

   Live co-authoring requires the file to be saved in OneDrive or SharePoint for syncing changes.

2. Step 2: Analyze other options

   AutoSave on and editing different cells support live updates; Excel Online supports co-authoring.

3. Final Answer:

   The file is not saved in OneDrive or SharePoint. -> Option B

4. Quick Check:

   Cloud storage missing = no live updates [OK]

Hint: Check if file is saved in cloud storage [OK]

Common Mistakes:

• Thinking AutoSave off causes issues
• Assuming different cells prevent updates
• Believing Excel Online blocks co-authoring
