Hi folks. Don't see much in searching for information related to IM/Presence exchange service in One-X portal connecting to Office 365, and I'm sure some of you talented guys have got this working by now. I'm using following information, if it's wrong please let me know...
Exchange service account name avaya@customer.com (customer's email address was too long to fit avayaadmin. seems it has a character limit)
exchange service host outlook.office365.com
exchange port number 993
I downloaded the powershell script and replaced all "AvayaAdmin" with "Avaya" and sent it to the customer as a shot in the dark hoping it would work on exchange online. Do any of you know if the script would be the same?
