Hi BandS,

Thank you for reaching out to Microsoft Q&A forum.

I understand that the incident involves Outlook (classic) displaying multiple empty Gmail folder sets after incomplete add‑account attempts. Below are the remediation steps to clean up and prevent recurrence:

1. Remove duplicate Gmail accounts (Email tab)

• Go to File > Account Settings > Account Settings.
• On the Email tab, select any duplicate Gmail entries > Remove.

This only removes locally cached data on your PC, your mail remains safely in Gmail.

2. Close redundant Data Files in the folder pane

• In the Folder Pane, right‑click the top of each redundant set > Close “Outlook Data File”.

This detaches it from Outlook but does not delete the file from disk.

• If Close is unavailable, it’s likely the default data file. Change the default data file or remove the related account first, then close it.

3. Reset default folders & Navigation Pane (clear “ghost” entries)

• Open Run (Win + R) and execute:
  • outlook.exe /resetfolders
  • outlook.exe /resetnavpane

4. Recommended: Create a fresh Outlook profile and add Gmail via OAuth

• Win + R > outlook.exe /profiles > Options > New (you can enable Prompt a profile to be used).
• In the new profile: File > Add Account > choose Google/Gmail > complete the Google sign‑in (OAuth).
• Ensure IMAP is enabled in Gmail: Settings > Forwarding and POP/IMAP > Enable IMAP.

5. Optional: Reduce Gmail labels shown via IMAP

• In Gmail > Settings > Labels, uncheck Show in IMAP for labels like Important, All Mail, Starred to keep the Outlook folder pane concise.

After completion, Outlook presents a single, active folder set for Gmail and the duplicate empty sets are removed.

Please feel free to let me know if you have any further updates.
