Hi all,

We have a new O365 Tenant with Domestic calling plan, E3 and phone system licenses.
I have set up a user with a number and with it, I can log into teams and make/receive calls on the number using the client as expected.

The problem I am getting is if I set the user to forward calls to my mobile or simring/delay forward calls to my mobile, the call just drops when this happens. This occurs for any external number. 

Coexistence mode is Teams only, external access is unrestricted, 

Does anyone have any clue why this would be happening? Are there further settings that need configuring?

Thanks for any responses.

Hi all,

Just in case someone comes across this thread with the same question, I thought I would update it with what we have found.

The forwarding only appears to work for users that have O365 exchange mailboxes. As soon as the mailbox is created, the forwarding (and voicemail for that matter) appears to work properly.

As we are currently migrating from on prem to cloud mailboxes, this should sort out our problem as we complete the process.

Hopefully this helps someone. :)
