following Issue occurs at a costumer site. We have
2 CAS NLB, 2 HUB, 2 MBX build as a DAG all on W2K8R2/AD
1 Service User, who does not belong to a protected group. This service user has fullaccess on the target mailbox/ad user in AD attributes and in exchange attributes
the Messaging API /CDO 1.2.1 is installed an all involved exchange servers
MFCMapi 32bit (V22.214.171.1241)
I log on to MFCMapi with my service user and create a profile using the CAS Array/Target Mailbox. Name resolution works fine at this moment. When i try to access the mailbox it is terminated with error MAPI_E_FAILONEPROVIDER == 0x8004011D. With Powershell get-mailboxpermission
and get-adpermission i have fullaccess rights for target mailbox with the service user.
Does anyone have an idea where to look at to get this resolved?
