Status: Service Degradation
Affected Service: Microsoft 365 for the web
This issue specifically affects use of the create a copy online
function and choosing a location that differs from the default location. Users
encounter an error that states, “Copy could not be created…There was a problem
creating a copy of this file. Please try again in some time.” Impact is
intermittent and retries may be successful.
To avoid this issue, users can access Microsoft OneDrive and navigate to the
files list, then click “Copy to” to create a copy; but if users open a file as a
Word document and attempt to create a copy from it, it may fail.

Users may be unable to answer PSTN calls from call queues using any Microsoft Teams client
Start Time: 2025-12-18 12:34(JST)
Last Update: 2025-12-24 02:43(JST)
Status: Service Restored
Affected Service: Microsoft Teams
When answering PSTN calls from call queues, affected users
experienced calls that remained stuck in a loading state, preventing connection
establishment.
While we worked on a fix, non-Virtual Desktop Infrastructure (VDI) users could
disable the setting (Settings, Devices, “Sync device buttons”) as a temporary
remediation.
For optimized VDI users that didn’t have the option to toggle the “Sync device
buttons” setting, some users could work around this impact by accepting PSTN
calls using a non-human interface device (HID).
