KB5022291 vs KB5021249

Hello team,

Based on my latest vuln assessment, there are some WS2022 that are still affected by several vulnerabilities because KB5021249 was not installed, although all servers are fully now updated with the latest update KB5022291.

My query is if by installing the latest update KB5022291, will not also fix the vulnerabilities that KB5021249 would fix.

thx,

micos

Outlook not connected in Microsoft Exchange Server

I am new to Exchange Server 2003 and I have a friend with a network server that I don't know how to re-establish a user to the network. I moved one of his non used computers to this station and now when I try to log in the user I get the error that the name can't be verified because Outlook is not connected or online. This computer used to be online with a different user. Can anyone tell me the steps to check this? Thanks.
