Excel Timoeouts in SharePoint and office 365

the Sophos template is outdated (May) and they do not publish updates to the list as soon as MS is changing things. you may need to add/remove some URL and IP ranges into the exceptions.

Compare with the list here: https://docs.microsoft.com/en-us/microsoft-365/enterprise/urls-and-ip-address-ranges?view=o365-worldwide

What did you import?

• API-O365-all.tar – this is a comprehensive set of 108 exceptions, every web URL that Microsoft list
• API-O365-required.tar – this a subset of 50 exceptions corresponding to the groups that Microsoft says are ‘required’
• API-O365-minimal.tar – this is a subset of 10 exceptions that correspond to the groups Microsoft says are

To debug: recreate the issue with one user, check the logviewer and look for requests without filtering exceptions. as already posted here shortly: community.sophos.com/.../skype-chat

Then evaluate if those requests belong to O365 and update exceptions accordingly.

I imported API-O365-all.tar but only enable all the urls with SharePoint and all the the URLs marked as required
