It sounds like you have an AV programming scanning the M: drive (The Exchange 2000 virtual Drive) or a backup program directly accessing the M: drive. This can cause what you are describing as well as possibly corrupting your data store. --Joe -----Original Message----- From: Keith Duemling [mailto:kduemling@xxxxxxx] Sent: Friday, December 27, 2002 7:01 AM To: [ExchangeList] Subject: [exchangelist] Unable To Read Emails With Attachments http://www.MSExchange.org/ Hello Everyone, I was wondering if anyone could give me some ideas beyond what I've already tried to resolve this issue. Running Windows 2000 Server SP3 with Exchange 2k SP1. Situation: Users began reporting email issues on the evening of Dec 24th. Some users are unable to open and read emails that have attachments of various sizes. They are denied because they don't have sufficient security settings per the email server. Individuals in the administrative group are not denied access at all. We have not made any security changes recently that we believe would cause this given our evidence. We are also experiencing a 6 to 10 minute delivery lag for internal users sending emails to other internal users, which appeared at the same time as the above mentioned issue. We've discovered that there are appx 1000 emails sitting in the queue folder on the server pending distribution to their destinations. Any help would be greatly appreciated.
