Offline address book not updating 2016
PNG It has been like this for a while now and hasn't error-ed out yet so I don't have an error message to go by.
In that case the whole OAB is being downloaded again.Essentially, the issue is the GAL is not updating in Outlook. I looked at the recipient filter of the GAL, it's below for reference: (Alias -ne $null -and (Object Class -eq 'user' -or Object Class -eq 'contact' –or Object Class -eq 'ms Exch System Mailbox' -or Object Class –eq 'ms Exch Dynamic Distribution List' -or Object Class -eq 'group' -or Object Class –eq 'public Folder')) The next thing I'm going to try is creating a new GAL and making it the default, if necessary. That will force Outlook to download a complete GAL. If so, it is probably that the incremental update files haven't updated correctly.We have another server in the wings waiting to be deployed, but we need to address the problem in the meantime. If it does not, then it is the generation or distribution process that is failing.If Outlook is left running constantly in Cached Exchange Mode, it automatically updates the offline address book about one time per day depending on updates on the computer that is running Exchange.The offline address book size can vary from several megabytes to hundreds of megabytes in uncompressed form.
