I was planning on using shared accounts instead of public folders because I need all of the mailbox functionality for rules and auto-replies and stuff. Plus, public folders always start as a post and you have to manually switch to a mail message. But, there will be about 25-30 users with access to all of them as additional mailboxes. They wont actually all be processing mail in them at the same time. The ones who are will only be reading, responding and deleting -standard mail functions. They wont be changing options or settings. Will this set up cause corruption? We are using Exchange 2003 and Outlook 2003.

You were told no on Experts-Exchange. It's the same answer and details here.

It would be nice to post the details here, as not everyone has an expert-exchange account.... As far as I know: In theory corruption may not occur on shared mailboxes as the Exchange databases are managed by the Extensible Storage Engine, which is a transaction based database engine which control data changes in a reliable way (ACID transactions). Also Exchange (post-sp2) uses ECC checksums to immediately detect and act upon minor inconsistencies. Cheers, Mark
