First scenarios: migrated user attempts to access on-premises elements.
- Access mailbox of another user (still on-premises)
- Access shared mailbox (on-premises)
- Access calendar (on-premises)
We will test these scenarios:
Grant Aisha Bhari Full Permission access to on-premises mailbox of Alannah Shaw
Result: Aisha can add the mailbox but cannot expand the folders:
Note: "Use Cached Exchange Mode" is unchecked.
I attempted the following for troubleshooting:
- Remove and re-add the mailbox? Still fails.
- Wait a couple days for permissions to take effect? Still fails.
Grant Aisha Bhari access to the Finance shared mailbox through membership in a security group granted Full Access.
Can she access the shared mailbox?
What if we grant her permissions directly (bypassing the security group).
The attempt still fails.
Can Aisha Bhari access the calendar of Alannah Shaw?
Moreover, we can only see the indication "Busy" on the test meeting (but not even limited details):
Granting more permission has no effect.
Send calendar invite to Aisha Bhari
This fails. I cannot even send the invitation:
- KB2956191 - already installed according to the installer
- KB2965295 - "There are no products affected by this package installed on the system" according to the installer.
- KB3114409 - "There are no products affected by this package installed on the system" according to the installer.
- Outlook Connectivity
- Outlook Autodiscover
- Exchange Web Services
What effect did enabling Outlook Anywhere have on the cross organization permissions and access tested earlier?
At first nothing. Nothing changed and Aisha Bhari could still not access the resources in question.
Moreover, Aisha can now locate and add the MktCal calendar...
She cannot open this appointment...
But that is due to lack of sufficient permissions rather than a faulty configuration of our hybrid environment:
When Aisha does have "Full Permission", she can view meeting details (in the calendar of Alannah Shaw)...
And in the FinCal calendar:
