Not getting the Auto save slider in excel but getting in powerpoint

Hi @Tuhin Bhowmick

Welcome to Microsoft Q&A forum 

As far as I know, AutoSave is no longer available or appearing in the Office toolbar in Office 2016 Version 1707 (Build 8326.2058) or higher. 

(Refer this link for more information: https://support.microsoft.com/en-us/office/autosave-is-missing-from-the-office-toolbar-9cc33369-9fb9-4e31-bb5c-af5f7a14ed82)

Regarding your issue, I suggest trying some basic steps: 

1.Update Excel to the Latest Version:  

-Open Excel. 

-Go to File > Account > Update Options > Update Now (on Mac, Help > Check for Updates). 

-Install all available updates. 

-Restart Excel and check for the AutoSave slider. 

2.Enable AutoSave in Quick Access Toolbar:  

-In Excel, click the down arrow in the Quick Access Toolbar (top-left corner of the window). 

-Select More Commands to customize the toolbar. 

-Ensure the Automatically Save option is checked. 

-Click OK and verify if the AutoSave slider appears.

3.Repair Microsoft Office (Windows):  

-Go to Settings > Apps > Apps & Features. 

-Find Microsoft 365 or Microsoft Office. 

-Click Modify > Select Quick Repair > Repair. 

-If the issue persists, try Online Repair. 

-Restart Excel and test 

These steps aim to identify the cause and may not permanently resolve the issue. I appreciate your patience as we work through this together.
