A couple of customers (heavy users) want to change over from POP3 to IMAP on our system so they can sync between multiple locations, all this is well and fine with me but I'd like to know where we would stand in terms of storing all their emails, attachments and any files on the server.
Is there any particular event with AMS such as re-starting the application or upgrading AMS to newer version for example where it could potentially lose all these stored emails etc?
Basically if we're going to be storing thousands of emails etc, I want to be confident that it's all safe and there is no known issue with AMS suddenly losing them all?
