    "tried couple of troubleshooting provided on public arctile but didn't helped."

    Such as?

    Have you tried?
    Adding the mailbox then removing? 

    Add-MailboxPermission -Identity "Jeroen Cool" -User "Mark Steele" -AccessRights FullAccess -InheritanceType All -AutoMapping $false

    then:
    Remove-mailboxpermission 

    Remove-MailboxPermission -Identity Test1 -User Test2 -AccessRights FullAccess -InheritanceType All

    https://learn.microsoft.com/en-us/powershell/module/exchange/remove-mailboxpermission?view=exchange-ps

    Also try this switch:

    -ClearAutoMapping
    This parameter is available only in the cloud-based service.

    The ClearAutoMapping switch specifies that the mailbox is automatically mapped (auto-mapped) by Autodiscover only into the mailbox owner's Outlook profile. The mailbox isn't auto-mapped to other users who have FullAccess permission to the mailbox.

    @Ramkrishna Trivedi

    Is the shared mailbox also hosted on Exchange Online?
    When did you modify the permission, before or after the shared mailbox and user mailbox are moved to Exchange Online?
    It may take some time for the Outlook to take effect after modifying the permission.

    Please use the command provided by AndyDavid to remove the Full Access permission, wait for some time to check if the shared mailbox is removed automatically. You also can check with Outlook online mode. After that, you can re-add the permission with "-AutoMapping $false", and add the shared mailbox manually.

    This been an ongoing issue for 3+ years. Is it possible devs could perform some check to make sure that outlook reflects what settings are actually performed in 365? If we need to remove access from a shared mailbox, shouldn't have to run follow up commands or complete the task twice over the course of an hour or so:

    Reference:

    We have to perform this action multiple times and have no real way to confirm it completed other than asking the user.
