I have a hybrid installation - Exchange 2007 on-premise (mailboxes/cas), with additional Exchange 2010 Hybrid servers for Office 365 integation. I am having calendar sharing issues from on-premise to Office 365. I think perhaps my sharingpolicy is not being assigned to my on-premise accounts. It is the default policy -- should it not apply to all accounts? The sharingpolicy for all on-premise accounts is blank. If I try to force a policy, I receive this error:
Property SharingPolicy can't be set on this object because it requires the object to have version 0.10 (14.0.100.0) or later. The object's current version is 0.1 (8.0.535.0).
Can anyone help with what this error means and how to correct it -- I assume the sharingpolicy should be populated - even though the 'default' policy is not being specifically assigned to accounts. Also, if I try in the GUI to assign to a specfic mailbox -- the selection window comes back -- 'no objects found'. The mailboxes are populated perfectly under the Recipient Configuration (Mailboxes) section. Thanks for your help.
