This was the last piece of the puzzle in moving my email from my old BB to my iPhone.
I can now read all email, even encrypted messages, on my iPhone. Buhbye Blackberry!!
This was extremely simple to setup. Launch the app, then open mail.app and select your Lotus Notes account. Open an email with encrypted content. Instead of the body of the message is text explaining that you should open the message using Lotus Companion. Then touch the highlighted text in the message which will bring Lotus Companion to the foreground.
At this point it auto-populates the Notes ID and server name, and asks you to type in your password. After entering my Single Sign On password (my corporate intranet password is different from my Notes ID password), the encrypted message then popped up within Companion.
Due to security concerns, you cant do anything other than read the message, but that is all I ever do anyways.
Note, if youre having trouble getting this to work (it wont populate your server and Notes ID, for example) then contact your Lotus Notes Sys Admin and have them add this function to your ID.
Dont confuse this app with Sametime, thats an IM client. Ill add my voice to the chorus asking for ST on iPhone, but thats a rant for another review
