Additional functionality is needed for office365 and azure probes (similar to aws probe) with the ability to access proxy servers; instead of putting in firewall changes each time a new IP/address is needing to be hit.
The azure probe has the possibility, to add proxy information and works fine on our site. We was very surprised, that it is not possible, to add proxy information for the office365 probe. This has to been added at the beginning of developing this probe.
We will check aws which supports proxy and will take this up as an enhancement request based on design discussions with architects and product managers.
This idea should apply to any probe that requires internet access.
