Im getting these in my event logs. Would really like to clear up these messages. Im not sure how to enable medium logging for the offline address book syncronization or where to determine what item in the syncronizations is causing this event. I have just turned on Address List Syncroninzation logging to medium under diagnostic logging on the particular server but Im not sure if this is the correct one.Event 9320OALGen could not generate full details for some entries in the offline address list for address list '\Global Address List'. To see which entries are affected, event logging for the offline address list generator must be set to at least medium. - Default Offline Address List Any pointers in the right direction would be appreciated.

Dear customer: Thanks for Jacks reply. He is right. To proper assist you to troubleshoot the issue, please help collect the following information. 1. Refer to the following KB to set OAL Generator logging level to Maximum, and rebuild of the offline address list.

Hey guys,Thanks so far. After enabling the logging for the oab it rebuilt last night and i had a couple 9323's this morning. Each one refers to an existing active user and claims they have an expired certificate. I then went into aduc and removed the certificate for each of the listed users. Im not sure if its that simple. I will let it go for another day or two to collect more logging and then in an email for review if the problem persists.

Dear customer, How's everything going? Rock Wang - MSFT

It looks like after removing the expired certificates this cleared up the problem.Thanks for the information and the assistance on this!
