Hi all,
Goiing over the Unity Connection release notes:
Cisco Unity Connection 8.6(2) Support for Microsoft Office 365
Revised 13 April, 2012
In Cisco Unity Connection 8.6(2) and later, you can configure Connection to synchronize voice messages in Connection user's mailbox with the user's Exchange Online mailbox configured on Microsoft Office 365 environment. Microsoft Office 365 is a cloud hosted collaboration solution provided by Microsoft.
Cisco Unity Connection 8.6(2) SU1 is qualified for 100 users with Microsoft Office 365. For scalability beyond 100 users, you need to contact UCBU Product Management team through ucxn-o365-support@cisco.com mailer.
Note 
The integration beyond 100 users will not be supported by TAC until the BU has signed off on it.
I was aware of the 19 users per Unified Messaging account issue, in which we created several UM Service accounts as a temporary fix until Microsoft lifts the limitation. I wasn't aware of the above that there is a limitation to 100 Users total.
There has been a few posts regarding the 19 user/account issue in which the workaround has been to create up to 20 UM accounts to get up to 380 users as a temporary solution.
Any insight as to when this will be lifted or detailed timelines would be great!
Thanks,
Chris
