Additional considerations

Group Policies

Many of the settings mentioned above can be enforced via Group Policies.

Script blockers

If you are using a script blocker software, please allow access to and from *.hoxhunt.com.

Firewalls and proxies

Some firewalls may limit or block connectivity to the Hoxhunt service. Please make sure you allow unrestricted access to and from *.hoxhunt.com. Proxies may also try to proxy *.hoxhunt.com which may cause issues, so you should bypass proxy for Hoxhunt.

Unfortunately the list of domains is not yet published in our Knowledge base. Please ask for a comprehensive list of technical Hoxhunt domains from Hoxhunt Support (support@hoxhunt.com).

Load balancers

Load balancers can also have an impact on Hoxhunt's performance. Load balancers should not be placed between Outlook clients and Exchange service, as this can cause issues for Outlook add-ins such as Hoxhunt add-in.

Closed Exchange Web Services (EWS)

In case access to your EWS is either closed or restricted from Internet, this can hinder Hoxhunt's performance and functionality. Hoxhunt offers some workarounds for this.
