Microsoft Outlook 2007 freezes

What are the causes that MS Outlook 2007 freezes? It's OK a few seconds after launching the application but when I want to do some action (e.g. write new e-mail) it suddenly freezes. Is there some troubleshooting?

thank you

I have experienced similar issues.

This was mostly related to either Xobni running or anti-virus. Try disabling anything similar you might have installed and see if the problem re-occurs.

Aside from that, you could always upgrade to 2010, but that might be cost-prohibited.

Recreating your .OST file should fix this issue.

Open Outlook>File>Data File Management>Data Files

Remove file name outlook.ost

Restart Outlook.
