The issue with this is that a new folder have been created due to the mailbox only allowing 1000 emails to be in the inbox and then all other mail goes back and forth with the inbox depending on what you are trying to search for.
Inbox - 1000 emails
OwaFV15 All focused folder - 50000+
I have turned off focused and the folder is still there and it seems like there is not way to remove this safely.
It works perfectly fine on outlook online (OWA) but Mobile, Mac outlook legacy and new are affected now. Mobile is affected due to mac outlook causing the issue.
The issue just appeared one day and I have also used a new mac and the issue was still there so seems like an issue with Mac outlook as it was replicated on a new mac.
What hasn't been tried so far:
* Used outlook on a windows
* Deleting the folder and seeing if that will fix the issue
