Is there a Hub for Win 10? I'm having issues with Classic Outlook Win 10.

If your Contacts in Classic Outlook where in a local "This Computer Only" folder (which is the default for any IMAP account like GMail) they will have to be moved manually to the New Outlook for Windows using Export/Import.

If you used classic Outlook before moving to new Outlook and you saved contacts locally, those contacts may not have copied over to new Outlook. To import locally saved contacts from classic Outlook to new Outlook, you need to export these contacts to a .csv file in classic Outlook and then import that file to new Outlook.
FYI - As far as a I know, none of the problems you are seeing have anything to do with Win10 vs Win11. It's all just Outlook.
When did Outlook disconnect from MS Windows? I didn't realize you could use it independently from Office? Who knew? But aside from that, when did Outlook start making folks package their contacts and re-import them into the same, upgraded app? That's yet another reason for never using it -- more ensh*tification.

I realize that this is closing the barn door after the horses have bolted, but to avoid the problem next time you remove an IMAP/POP account from Classic Outlook -
You can create a local PST file and make it your Outlook "Default" data file independent of any that Outlook creates for an email account. Once you've done this, any Contacts or Calendar events you create for an IMAP/POP account will be saved in this PST. Not in the OST file that is tied to a specific instance of an email account.
You can even move the PST file to a new PC with a new instance of Classic Outlook and all you have to do is make it the Default Data File and all your data will be available.
I can not include the actual URL to the instructions on how to do this because it's on a non-Microsoft site.
A Google search for something like this should get you some hits:
Outlook Classic. Create a PST and set it as the default data file for Calendar and Contacts instead of the OST that Outlook created

This is a quirk of Classic Outlook when you are using a non-Microsoft account. e.g. GMail, Yahoo. Anything where Outlook uses the IMAP or POP protocol to sync with your email provider.
IMAP and POP are only for syncing email. The protocol has no provisions for Calendar or Contacts. So Outlook creates some "This Computer Only" folders on your PC to locally store any Calendar events or Contacts you create for that email account.
These local folders are tied to a specific instance of an email account. e.g. When you add a GMail account, Outlook creates some local folders that are tied to that instance of the email account. If you then remove that account from Outlook, the linkage between that instance of the email account and the local folders for that account are lost. Even if you add back the exact same GMail account, Outlook will create a new, empty set of local folders. Hence the need to export the contents of these folders before you remove the email account and import them back when you add the account back.
It is not very intuitive. Even long time Classic Outlook users forget about this quirk and don't remember to export the "This Computer Only" folders before removing an account. (Myself included on more than one occasion).

I'm not sure I understand. Office has always been "disconnected" from Windows. i.e. Any recent Office version will run the same on both Windows 10 and Windows 11.
