Hello,
I recently created 2 new System Databases at Exchange 2010 SP2 and moved all users' mailboxes there. Analyzing Application log, I found that Exchange keep changing System Maibox GUID to another one and then after some time it is changing it back to the
original. I'll be much appreciate for any ideas why it is going on.
Please see logs bellow:
The mailbox GUID of an external system mailbox ('Mailbox - SystemMailbox{5e47975b-8070-4bba-8429-b721752b8a6b}') does not match the information in the Active Directory for the mailbox. The existing GUID ('41d53168-4f05-4a7e-940f-0a63b69e80d6: /o=XXXXXXXXXXXXXX/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=SystemMailbox{5e47975b-8070-4bba-8429-b721752b8a6b}') has been replaced with the expected GUID ('1be9ad2e-4c77-48e0-b0fd-d10e49ef320d: /o=XXXXXXXXXXXXX/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=SystemMailbox{5e47975b-8070-4bba-8429-b721752b8a6b}').
