I have just installed Microsoft Office 2021 and have run into a problem with the installation of outlook.
In starting I get following error popups. The network is available, there are no other windows open,and as to the comments to the first window I have no clue as to what and where it is looking for info. Refer to attached jpegs.

Later I had to log onto Admin. and MS TEAMS popped up. filled out info and then closed it down. Outlook immediately opened up and had full access to it. Logged back into my profile and tried to open Outlook with the same results as initially described.

did you have it installed on the D drive?
All installed on C drive. It was myriad of small problems in Outlook setup, I don't know how a few happened.
