I am using Microsoft Outlook 2007 to download mails from my Yahoo Business Mail account using IMAP. Mail downloading is working fine, and Yahoo's technical team confirmed that Yahoo supports IMAP.
However, Outlook hangs quite frequently and responds after a really long time. I have searched on google, and applied the solutions like disabling Add-Ins.
My PST file size is only 75 MB.
What could be the issue? My operating system is Windows XP Service Pack 3. Outlook version is 2007 (12.0.4518.1014) MSO(12.0.6514.5000)
