Final answer:
To restrict access for one location in Office 365 without affecting others, you can use conditional access policies based on location.
Step-by-step explanation:
To restrict the access of one corporate location to Office 365 services without affecting other locations, you can apply conditional access policies based on location. This allows you to set specific rules and restrictions based on the IP address or geographic location of the users. By configuring conditional access policies, you can effectively limit the access of certain locations to Office 365 services while allowing others to continue using them.
For example, you can create a conditional access policy that blocks access to Office 365 services for users who are originating connections from a specific IP address range or location. This way, you can restrict the access of a particular location while ensuring that other locations can still use Office 365 services without any issues.
Implementing a new firewall rule for each location or using a VPN for all locations are not recommended solutions in this case. These approaches would either require managing multiple firewall rules, which can become complex and difficult to maintain, or forcing all locations to use a VPN, which may not be necessary for locations that do not have any restrictions.
