MS Exchange GAL and OAB not matching
Posted on 2012-09-04
We converted a client from a single Exchange 2010 box to a cluster, 2 CAS, 2 MB, 1 DAG. Ever since the conversion, some users do not show up in the GAL (they do if you do an advanced find, but not in the GAL list) if you use an OAB. As soon as I turn off the OAB, everything is fine. Turn on OAB and download it, they disappear. Catch is, this seems to only affect certain users. I have come up with the reg hack to stop OAB download and use the GAL from the server, but I dont want to implement that for all users. I can log in with my account and all is well. Affected user can delete OAB and redownload and the issue returns.
Anyone seen this before?
