Email read on bb not on inbox on office comp

I am running into an odd issue where I have a couple of emails on my BB, which are also on each of our staff's computers at the office.

I am noticing if I read an email on my q10, it doesn't show up on anyone else's inbox on their computer or phones. This doesn't happen with every email, but the vast majority. All of our email accts are Imap. and gmail.

Would anyone know a way to get around this as I need to be able to read an email while on the road, but also know the email is making it to the inbox's in our office as well. I am currently having to forward the email after reading it to them to make sure they have it as well.

thanking you in advance for your assistance... Mike

Make sure you set your HUB (well, all of you set the HUB) to delete on device only.
