[cisco-voip] Exchange Hybrid - presence gateway

[Erick Wellnitz]

All,

I have a client with a hybrid Exchange/O365 system.

I have an issue where free/busy information is retrieved successfully from
Exchange users but not O365 users.

O365 users return a 'mailbox not found' error along with the contents of
this SOAP message.

11:38:35.878 |system.pe.eal.ews 573278 DEBUG <?xml version="1.0"

We know the mailbox exists because the person can send and receive mail
without issue.

Any ideas or advice?
