Send items wrong folder on outlook 365 and macos

[Ankou666]

Good morning,

One of my client has an issue on outlook 365 on her Mac Mojave.

She has two mailbox, and when she send a mail from the second mailbox, the mail doesn t go on the folder send item of this one but on the send folder of the first one.

It seems there is a register key on windows to solve that but on Mac I don t find anything.

Thank you for your help

Is this a shared mailbox?

@Ankou666 

as @adam deltinger suggested.. seems that the user is sending mails using a shared mailbox... and the mail is showing in sent items of the user mailbox...

In case if it is not a shared mailbox.. did you check in OWA if the same issue is there or not..?

Thanks
