I have a Windows XP Home Edition Laptop with Office 2000 including Outlook 2000 SP3 installed on it. Everything was working just fine (sending/receiving emails) and using Send To from other applications like Word, Excel and Access, etc.
This may sound a bit strange but a few days ago seems like Outlook 2000 on this machine went into Exchange Server mode. In other words, when I try to configure mail accounts, etc. from the Tools menu, Accounts is no longer an option and now Services is the available option.
Although I configured the mail accounts with the Services option ...What happened to the Accounts option???
Also, now when I try to send an email from let's say Word or Excel, I get the following error ...
"An error occurred while attempting to open the Windows Address Book."
MAPI 1.0 
Any help will be appreciated ...
