Microsoft 365 • Retention regarding backup change

Been involved with Veeam for a very, very long time, but new to the cloud stuff.

We currently have Veeam Data Cloud for M365. We have the flex variable license. My rollout was a bit rushed and I should have asked these questions early on. So, thanks in advance to anyone that can help me understand the process.

Questions
(1) We have offboarded a user who left for another company. I have released the M365 from the user and converted their mailbox as a shared mailbox. I still have the user in the current VDC backup config. I have extra licenses and Veeam is complaining this user, still in the backup job, has no M365 license. I get that. If I removed this user from the current backup job, will the user's data still be accessible? When initially setting up VDC, I believe I set retention for 7 years or higher. Everything seems to be working like clockwork as you would expect from Veeam, but I'm a bit fuzzy before removing this user from the job and wanted to get confirmation of my understanding.

(2) While playing with the settings, I see the same user as a different object that I can add to an existing backup job, but is definitely noted as a shared account. Once I remove the original user, can I assume I can add back this user as a shared object with no license warnings?

(3) Lastly, I have been poking in the portal and can't seem to find what my initial setting that I chosen for retention. I know VBR like the back of my hand, but VDC not so much just yet.

Thanks in advance.
