Call 8x8 Support

This issue has been resolved for secondary admins in Virtual Office Configuration Manager. If you are experiencing this issue, please call 8x8 Support.


For Virtual Office Editions and Virtual Contact Center Editions users who are not the primary administrator of the account, this was due to a permission limitation which allowed only the primary administrator access to the Support case portal at this time. This issue is resolved for secondary admins in Virtual Office Editions and Virtual Contact Center Editions.

For all other users (including Virtual Office/VCC Editions primary administrators), this is an intermittent issue and is under investigation. It is correctable with 8x8 Technical Support assistance.
