[NCUC-EC] [NCUC E-team] List problems

[Gannon, James-1]

The whitelist may take up to 48hours to go into effect across the various Microsoft internal systems. Just FYI in case there is a delay in receiving mails.

I think the matter may have been sorted. Now I realize I have not been receiving my responses and yet this should be the case.

Thanks Tapani :)

Thank you so much Tapani for taking this up. I actually notice that my response to the list yesterday also bounced. Hope we resolve the matter. If not, then I can be subscribed using my kictanet email address.
