Outlook oab not updating
Next we renamed the folder containing the OAB files (the folder with a name that looks like a GUID).
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).
I will be updating this article to see if I can find a version where this did not occur.
I am thinking either pre-CU7 or Pre-CU5 would be the place to find it.
Open up the latest log file in the directory and see what errors are being reported by the client.
In our case, we had these error messages: Notice the error “Is Local OABFile Current: Manifest Enforcement Disabled And Local File Too Old”.
