Microsoft Sway - Issues with duplicating, running slowly and issues adding images

Dear @Rebecca Jenkin,

Thank you for reaching out to Microsoft Q&A Forum!

From your description, I can see you have problem with:

• Errors when duplicating a Sway publication
• Slow performance across browsers (Edge and Chrome)
• Delays when uploading images and loading publications, even on multiple devices

To assist you effectively, could you please confirm the following:

1. Is this issue affecting only Sway, or are other Microsoft 365 apps (like Word, PowerPoint, etc.) also running slowly?
2. Do you know if your organization uses any network restrictions, firewalls, or proxy configurations that might affect cloud-based apps like Sway?
3. Since your SAP is listed as “Microsoft 365 and Office | Sway | For education,” have you tried contacting your school’s IT department? Do you know if other users in your tenant are experiencing similar issues?

In the meantime, here are some steps you can try:

• Clear browser cache and test in an InPrivate/Incognito window to rule out extension conflicts.
• Verify your OneDrive storage, as Sway relies on OneDrive for content hosting.
• If possible, test on a different network (e.g., mobile hotspot) to eliminate network-related latency.

If these steps don’t resolve the issue, please let us know the answers to the questions above and any error messages you see when duplicating the publication. This will help us narrow down the root cause and provide a tailored solution.

Because this may involve tenant-level settings or network restrictions, I also strongly recommend contacting your school’s IT department. They can verify if there are any policies, proxy configurations, or bandwidth limitations impacting Sway performance and check if other users in your organization are affected.

We appreciate your kind patience and understanding that sometimes the initial response may not immediately resolve the issue or there may be some misunderstandings about your scenario, but we would love to hear updates from you and find out further suggestions.

Best Regards.
