Why can't I edit my own contact info in Global Address List of Outlook client?

The environment is on-premise exchange server 2016, in the ECP/Exchange Admin Center I already have user accounts set up with

Our outlook client version is the latest Microsoft Office 365,

In the past at other places I was able to within the GAL field itself on the client version of Outlook to directly edit my own self contact info, etc (and so did every other user) without having to go to the OWA or use a browser and without having to use RSAT/ADUC tools etc

    Because the environment has not been configured to allow this. You need to speak with your IT staff about the correct method of updating this info in your environment – music2myear Dec 7 at 2:37

    I'm voting to close this question as off-topic because it is about corporate IT and only OPs IT staff will be able to answer the question as it has been asked. – music2myear Dec 7 at 2:39
