I also have this issue which is clearly a bug in either outlook(on the web) or the browser. We are using only standard Microsoft products (Windows, Edge, Outlook web), all up-to-date.

Side note: The AI response is akin to saying - turn off your computer and problem won't occur.

Several users in my company have reported similar incidents : moving a message to another folder within Outlook web (in their web browser Chrome) would result in the tab becoming frozen.

Hi Florian,

In your situation, I recommend contacting your company's IT administrator and asking them to create a support ticket through the Microsoft 365 admin center by navigating to Support > Help & Support for further investigation.

This route ensures you can contact a technical support engineer who can perform a remote session to investigate the situation, verify the backend configurations, and run any necessary synchronization tools to resolve the problem. If the issue requires further attention, they can escalate it to a specialized team for deeper analysis.

For detailed guidance on how to open a support ticket with Microsoft Support, please refer to: Get support - Microsoft 365 admin | Microsoft Learn

If you do not know who your IT admin is, kindly refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support

I had this issue just now. But it was for Outlook (new). I found the answer was to delete the Outlook (new) webview cache. Navigate to

C:\Users[Your username here]\Local\Microsoft\Olk\

Then delete the EBWebview folder.

This won't log you out or anything, it's just the cache. New Outlook is just a website. So I'm going to guess that if you clear your browser cache/history in whatever browser you're using, it might also fix it for you.

Hi,

For the best possible assistance, can you share more details about your situation? I appreciate your cooperation and understanding.

Which browser and version are you using?
Does it also happen in another browser, such as Microsoft Edge or Google Chrome?
Is this affecting only your account, or other users as well?
Does it happen with all emails and attachments, including small files?

As an initial test, please open Outlook in an InPrivate/Incognito window. If drag-and-drop works there, clear the browser cache and cookies for Outlook, then temporarily disable browser extensions, especially ad blockers or security extensions.

I want to ensure I have clear information to provide appropriate guidance. Should you need further assistance, please feel free to reach out again in the comments of this post. I'm happy to assist you further.

It seems working better now that I posted this, strange!

I use Edge. Cannot say for other browsers or account.

It was for all emails and attachement

Thank you for your support!

For Outlook on the web, use the non-drag methods as the immediate workaround:

To move an email, select the message, then use Move on the ribbon, or right-click the message and select Move or Copy to folder.
If the destination folder is not shown, select Move to a different folder and choose it from the full folder list.
To move multiple messages, select them first, then use the same Move action.

For attaching an email to another email in new Outlook, drag and drop is supported there by dragging the message into the message being composed until Drop messages here appears.

If the issue is specifically that drag-and-drop freezes the page in Outlook on the web, a documented workaround for move failures is to keep using Outlook on the web move commands instead of drag-and-drop. If the mailbox is hosted with a third party using IMAP or POP3, use that provider’s webmail to move items.
