Is your Outlook 2007 autocomplete (NK2 cache) suddenly slow?
As some of the users that asked me this question, you might have noticed that your Outlook 2007 autocomplete cache is suddenly quite slow. Even worse, the bigger the NK2 file is, the more slower it gets..
It seems that the problem is caused by the buffer overflow protection settings of the McAfee virusscanner. Until McAfee fixes the issue, you can exclude Outlook from "protection" by adding an exclusion locally for outlook.exe under Buffer Overflow Protection settings:.
- Click, Start, Programs, McAfee, VirusScan Console.
- Right-click on Buffer Overflow Protection and Select Properties.
- With the Buffer Overflow Protection tab selected Click Add.
- In the Process name field type the following: outlook.exe then click OK.
Note: if the options are unavailable or greyed out, youre scanner is probably managed by EPO. See your EPO admin if thats the case.
