Hi Jens,

Can you see this article https://support.microsoft.com/en-us/help/3042584/-proxy-address-address-is-already-being-used-error-message-in-exchange-online

Have you tried to create the shared mailbox by powershell ?

Hi Nuno,

Thanks for your reply.

I have not tried Powershell as I have no experience with it (and also I am working in Apple OS X). I have no Exchange experience, but if this solves the problem I will try and connect to it and try to figure it out.

Being on Mac does make it more tricky, if you're involved in Office 365 admin you need access to PowerShell sooner or later. For Macs, having a Windows VM (Parallels/VMware/VirtualBox) or Bootcamp would be easiest assuming there are no accessible Windows PCs/servers. This is a good page to get started - https://support.office.com/en-us/article/PowerShell-for-Office-365-administrators-40fdcbd4-c34f-42ab-8678-8b3751137ef1 and https://channel9.msdn.com/Events/Ignite/Australia-2017/PROD323. Good luck anyway.
