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.
