Lately, Outlook 2003 has been leaving a process in memory after I close it. Currently (15 minutes after I last used Outlook), it's 46,756K. Any way to fix this?
 
Under normal conditions, outlook.exe might run up to 2 minutes after you close it - but 15 min is too long. This is usually caused by a program running that accesses outlook's data file - sync utilities are most common, but there are other programs that will do it too.
 
The problem has worsened since the Win 10 Anniversary Update. At first, Outlook would not let me save calendar entries if the stub had been present when I opened the program; all other functions seemed OK. Lately, if I start the program without killing the stub, Outlook sometimes says it can't open files, or something like that. And today, I noticed that if I killed the stub, it often kept reappearing, each time using a different amount of memory.

I suspect it's CompanionLink for DejaOffice, the only program I know of that access my Outlook data; I just tried closing it from task manager, and the stub has not come back. But you mentioned other programs might cause this--which ones?
