Microsoft Outlook 2007 freezes

Question

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

Answer 1

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.

Answer 2

Recreating your .OST file should fix this issue.

Open Outlook>File>Data File Management>Data Files

Remove file name outlook.ost

Restart Outlook.

Answer 3

The real cause behind Outlook freezing or hanging is the increased size of the Outlook .pst file. To be more specific, the size of .pst file exceeds 2GB or its upper limit. Due to this, any general operations like writing emails, deleting etc get affected and do not work.

To fix the above issue you can try any of the below:

• Decrease the size of your Exchange Mailbox
• Instead of using cached mode profile use an online mode profile
• Split your large Outlook .pst file into various small manageable parts.

Moreover, you could also try some third party PST file splitter software as this splits the PST file in a fast and secure manner.
