如何隐藏/删除Outlook for macOS 2016(16.10)内置文件夹？

I’ve dealt with this exact frustrating issue before—those empty, unused built-in folders that keep popping back up right after you delete them. The good news is we can hide them for good instead of fighting the deletion cycle. Here’s how to tackle each one:

Clutter #

Clutter is the simplest to hide thanks to Outlook’s native settings:

• Open Outlook and head to Outlook > Preferences from the top menu bar.
• Select Accounts, then pick your email account from the left sidebar.
• Switch to the Mail tab, then uncheck the box next to "Enable Clutter".
• Restart Outlook, and the Clutter folder will disappear from your folder list.

Conversation History #

This folder is tied to Skype for Business/Microsoft Teams integration. To make it vanish:

1. First, turn off conversation sync:
   • Go to Outlook > Preferences > Accounts, select your account, then switch to the Advanced tab.
   • Uncheck the option labeled "Save conversations from Skype for Business in Outlook" (the wording might be slightly different in 16.10, but look for any setting linking chat history to Outlook).
2. Adjust folder visibility:
   • Right-click anywhere in your folder list, then choose Folder List Settings.
   • Find "Conversation History" in the folder list, uncheck its box, and click OK.
3. Restart Outlook to lock in the changes.

Groups #

Groups are linked to Office 365 Groups, and you can hide them via account settings:

• Open Outlook > Preferences > Accounts, select your email account.
• Look for the Groups tab (if it’s missing, double-check your account is connected to Office 365).
• Uncheck the box next to "Show Office 365 Groups in folder list".
• If the folder still lingers, right-click the Groups folder in your list and select "Hide" (this option should appear once sync is disabled).
• Restart Outlook, and the Groups folder will no longer clutter your view.

A quick important note: These folders are part of Outlook’s core structure, so deleting them will always trigger Outlook to recreate them. Hiding them is the only reliable way to remove them from your daily view.
