What would make a Shared Mailbox NOT show up in Outlook (2016, ProPlus C2R)?
What setting would make a Shared Mailbox NOT show up for a user? User is using Office 365 ProPlus (click to run), version 2016 (first release deferred channel).
Option 2 is what I am asking about, permission has been removed and re-added a few times now (over the course of a few days). It works for other people, including myself.
I am curious if it is a setting perhaps, but before we go digging around his computer and Outlook settings, would like to know what we should be looking for.

A couple times a user here hasn't seen the Shared Mailbox in desktop but did in OWA, we would delete their Outlook profile and recreate it. That, for us at least, got the Shared Mailbox to show up.
- So a bit more clarity (user is in Europe), was able to determine the mailbox WAS showing up, just couldnt be used.
The setting "use exchange cached mode" was not checked, which as soon as it was, user was able to start seeing emails and folders.- Victor_Ungureanu

If the mailbox was showing up, then the shared mailbox was pushed through autodiscover to Outlook client. Next step performed by Outlook is to run autodiscover on the address of the shared mailbox and this is where is probably failing.
You can run test email auto-configuration on the address of the shared mailbox, without any credentials. If prompted for credentials, type in the upn and password of the user having permissions over the shared mailbox.
If you have a hybrid environment (autodiscover pointing to on-prem) and the shared mailbox was created directly in cloud, then this is the cause.
