Dear SF123SFSI,
Greetings! Thank you for posting in the Microsoft forum.
Please try running Excel in safe mode, check if you still experience the same problem. To know how to start Excel in safe mode, see Open Office apps in safe mode on a Windows PC. When Excel app opens, check if the ribbon is active, if not, click File>New>Blank workbook, now go to Data>Get Data>From Other sources> From Microsoft Exchange. To identify if Excel is running in safe mode, check the top ribbon, it should appear as the screenshot below.
If it works fine in safe mode, it might be possible that there’s an add-in which is affecting the performance. While in Excel safe mode, follow the instructions below to identify which add-in is causing it to happen:
- Click File > Option > Add-ins, then click Go in the Manage: COM Add-ins.
- Clear the checkbox if you'll see any add-ins, then disable them.
- Close Excel app and relaunch it after.
- Check if you'll still get the same behavior.
We appreciate your understanding that sometimes the initial suggestion may not resolve the problem. However, we can work together to narrow down and resolve the situation. If the issue persists, please provide the following information:
- Please provide the screenshot of Microsoft 365 Product Information. To get this screenshot, open Word or Excel, click File>Account, capture the screenshot of all the information mentioned under Product Information.
- May I know if clicking any other option (such as From web or From SharePoint or From Active directly etc.) shows similar behavior?
We will look forward to your reply. Stay safe and stay healthy.
With sincerest regards,
