Are you sure the permission isn't inherited?

Have you tried removing it via PowerShell, use the Remove-MailboxPermission cmdlet. If the mailbox is located in ExO, you can also "reset" its permissions, or clear Automapping: https://www.michev.info/Blog/Post/1382/removing-automapping-and-resetting-default-mailbox-permissions-in-exchange-online

Mailbox is located in O365. Could you please send the powershell cmdlet ?

To reset the permissions to default:

 Remove-MailboxPermission mailboxname -ResetDefault

To only clear automapping:

Remove-MailboxPermission mailboxname -ClearAutoMapping

The article above has more details/examples.

Hello Justin

Use the Remove-MailboxPermission cmdlet to remove permissions from a user's mailbox or from an Exchange Server 2016, Exchange Server 2019, or Exchange Online mail user.

For information about the parameter sets in the Syntax section below link,

https://docs.microsoft.com/en-us/powershell/exchange/exchange-cmdlet-syntax?view=exchange-ps

You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not included in the permissions assigned to you.

Follow the link below for further assistance,

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

Hope this answers all your queries, if not please do repost back.
