Memory Leak in Outlook 2007?

[javatopia]

This is from my thread started in the Office General Questions discussion
group:

I am running Outlook 2007 (12.0.6504.5000) SP2 MSO (12.0.6425.1000)

Today I restarted outlook after it was at over 850MB in virtual memory.

Startup is at 65MB. Then about 2 hours later (15 POP3 accounts checked every
15 minutes), it's at 125MB and growing.

There is definitely a memory leak in Outlook 2007. This appears to be a
recent addition, as it was not an issue when I first installed Outlook 2007.
The only *new* component I added was F-prot Antivirus. I also updated Adobe
Acrobat Pro to version 9.

I did not do anything unusual during this session. Just read email from my
inbox and delete spam mail. No filter changes, no PDF generation, no
printing, no calendar access, no contacts access, no synching, nada, just
reading email from inbox.

I also started outlook in safe mode, and it used 52 MB of virtual memory in
45 minutes of doing nothing but checking email and viewing email.

I am on Win XP Pro 64 bit. All updates have been installed.


Thanks

Is F-prot Antivirus scanning the email? If so, there is your likely
suspect. Uninstall it an reinstall without the e-mail scanning section.

Hello,

In safe mode, the F-prot scanner is no longer active. Even in safe mode,
Outlook 2007 continued to leak memory (52MB in 45 minutes).

None of the plugins appear to be the culprit, but that does not mean they do
not compound the problem further ...

You said, when you installed it there was not a problem. Then you say
the only new addition is F-prot. Unless there is some other upgrade or
patch you installed or allowed to install? Please be aware that "not
active" and "not affecting" is not necessarily the same thing.

It is actually leaking or just using more than you think it needs?

Antivirus scanning email and the acrobat addin could be a factor but outlook
will take as much available memory as it can get and release it as the
computer needs it. It should release it when its minimized, with most
released when minimized to tray.

52MB is not a whole lot and does not directly indicate any issue. Especially
not compared to the 850MB that you referred to which of course is an obvious
issue. The fact that it works correctly in Safe Mode indicates the issue is
most likely with an add-in that you have installed.

Note that if the computer has a lot of RAM available, Outlook can get it
assigned by Windows when it requests for it; why waste the free RAM? Windows
Vista and Windows 7 does this even better and tries to use all RAM as
efficient as possible and takes it away when another application really
needs it.
