Error exporting file as PDF: The online service is not available in your region.

On MacOS 15.5 with the latest (enterprise channel) or Microsoft Office

We have a issue currently that certain users in different location is getting a issue when saving as a pdf when the option 'best for electronic distribution and accessibility is selected.

"Error exporting file as PDF: The online service is not available in your region. Please contact your administrator."

This uses the Microsoft online services 

when using 'best for printing' - it works fine as thats a local pdf printing and does not use MS online services

the region is set to UK 

we are going to look at the locations and see if any traffic is being blocked as well
