Have customer with outlook 2010 sp2 runnning on Win 7 sp1. The email is hosted externally. All the sudden he is getting delay when trying to attach files to emails. The attachment browse window open but there is a delay in enumerating all the folders. It will show the Inseert File window and may say not responding for a few min before enumerating all the folders and allowing attachment functionality. I tried disabling all add-ins and also opening Outlook in Safe Mode. Neither made a difference. I tried also deleting the outlook profile and setting up with a new profile which didn't make a difference. I next logged off as that user and logged on as another domain user and setup Outlook. Attaching files from that user works fine. Need to figure this out as quickly as possible. Thx.
