Exchange global address not updating

I verified the file location manually but also noticed the date discrepancy (the blue rectangles in the above image) which shows the date the attempted download was made (upper left) and the date of the files (lower right).Because the files were not changed recently the error message was downloaded and the client could not download the files.Another way to make sure that you get a fresh copy of the OAB is by renaming the oab-files to when Outlook is closed.They are stored in the following location: which itself holds subfolders with named after Account GUIDs.I might have a problem with my Offline Address Book in Outlook.For me, new colleagues are not showing up and the contact pictures aren’t displaying either.Further Troubleshooting Let’s see where the OAB generating mailbox is and if the database is mounted.We should also check to make sure we can update the OAB using Power Shell.

Next we renamed the folder containing the OAB files (the folder with a name that looks like a GUID).Once renamed, we tried to update the address book and restart the Mailbox Assistant service. The Fix After some more troubleshooting in the event logs and diagnostic logging, I noticed that the database copy for Database02, where to OAB mailbox resided, had one copy that was in a ‘Failed and Suspended’ state.We tried to fix this copy and were unable to do so with a reseed or a resume.This would leave the source database mounted and the destination (the second database copy) would end up in a “Failed and Suspended” state.What ended up happening is about a day later if a user tried to manually download the address book, they would not be able to and would get a 0x80190194 error: Troublshooting So what is this? Well, let’s look at the log files for OAB downloading.
