I receive the following error below when I create resource mailboxes. Does anyone know why?
Note: This is a hardened environment to STIG and NIST GCB.
A) Rooms seem to function properly after I create them. I can schedule meetings, etc. But I receive this error every time I create one.
This mailbox was created successfully, but some properties weren't saved. Close this message, then in the Mailboxes list, double-click this mailbox, set the properties, and click Save.
Modified the error to remove organization-specific config. It shows the proper org info for CN and O in my message.
Additional Note
So it seems when I went into ADSI Edit, the System Attendant "homemdb" field was blank.
During initial configuration of the Mailbox servers, I had created a new Database (and replicated it), migrated the Arbitration mailboxes to the new database.
However, it seems that this field was never updated or changed. I tried modifying the homemdb field to the proper MailDB DN. I performed this for both mailbox servers' System Attendants in AD and am waiting for replication to see if this fixes it. I may have to restart my mailbox server. Restarting the Information Store or Mailbox Assistants services did not change anything.
