I recently upgraded one of our clients from Symantec Corporate Edition 10 to 10.2. After the install of the new version on the clients. Some of the Windows XP machines with SP2 had a problem with outlook.

When they launched outlook they received a message:

“The add-in”C:/Program Files/Symantec AntiVirus/vpmsece3.dll” could not be installed or loaded. This problem may be resolved by using Detect and Repair on the Help menu.”


I resolved the problem by deleting the Extend.dat file.

Here are specific instructions.
1. Go to MY Computer
Double click on C: drive
Go to Tools => Folder Options (Make sure, show hidden files and folders is checked)
Double click on the documents and settings folder
Double click on the folder that has your Username
Double click on Local Settings Folder
Double click on Application Data Folder
Double click on Microsoft
9. Double click on Outlook
10. Delete the file Extend.dat

Exchange 2000 Storage Limits (Big Problems)

I am sure that everyone working with Microsoft Exchange has had their share of problems. The problem I was faced with yesterday was that Exchange reached it's database storage limit of 16GB. The Exchange database consists of Mailbox store (priv1.edb), public folder store (pub1.edb) and the stem files priv1.stm and pub1.stm.
Once Exchange reaches the above limit you will not be able to mount the Mailbox store and your users will not be able to log into Exchange client (outlook). If you are running your clients in Online mode, I am mixed... Offline for mobile users, online for users that stay in the office.

Please note that there is a microsoft registry hack that will let you increase the above database size of 16GB to 17GB temporarily by applying a hotfix, however this is not a permanent fix and it did not work for me.

The only way for me to be able to mount my database was as following:

1. Run ESEUTIL (Exchange offline defrag) for syntax see below
2. Run Exchange Mailbox Management with custom settings to shrink the mailbox sizes of users with excessive attachments. I customized the Mailbox management settings under the Recepient policy to delete all emails that are more that 3mb in size. We are a cpa firm and often receive file attachments that are massive. Most of the times the 3mb files will become obsolete very quickly.

ESEUTIL syntax:

Exchange 2000 server includes a utility called Eseutil that replaces Edbutil and Eseutil utiliites that are included with earlier versions of Exchange

For more information on how to use Eseutil and various switches available for the utility please read this article on MS Knowledgebase
