How remove a recently added tab from the ribbon in classic Outlook

Hi @Reid-7439,

Thank you for posting your question in the Microsoft Q&A forum.

Regarding to your question about customize the ribbon, you don’t need to use Reset (All Customizations). Here are three cases you can try depending on what exactly was added:

1/ If you enabled the Developer tab itself:

• File > Options > Customize Ribbon.
• In the right pane (Customize the Classic Ribbon), ensure Main Tabs is selected.
• Uncheck the checkbox next to Developer.
• Click OK.

This simply hides the Developer tab and leaves all other tabs/groups intact.

2/ If you added a Developer group into the Home tab:

• File > Options > Customize Ribbon.
• In the right pane, expand Home (Mail).
• Select the Developer (custom) group you added under Home.
• Click Remove (button below the tree).
• Click OK.

This removes only the custom group from Home, not the entire tab.

3/ If you tweaked the Home tab and want to undo just those changes:

• In Customize Ribbon, select only Home (Mail) in the right pane and uncheck all other options.
• Open the Reset dropdown > choose Reset only selected ribbon tab.
• Click OK.

This reverts the Home tab to its default state without affecting other tabs or your Quick Access Toolbar.

To identify which case you can apply:

• In the right pane, if 'Developer' appears as a top-level item with a checkbox (similar to Home, Send/Receive, or View), it indicates that it's a tab, you can enable it by checking the box.
• If 'Developer' appears nested under 'Home' and displays '(custom)' when selected, it means it's part of a custom group, in that case, please follow option 2.

After you make the change, close and reopen Outlook if the Ribbon doesn’t refresh immediately.
