Take away the "You're Connected to too many services" message.
This message is getting old. My computer and internet connection are capable of many more connections than I have and the message is annoying. I have multiple accounts for a reason and I need to be able to use them all in Outlook for Mac.
This issue is very frustrating! It appears that this is related to the number of services connected in Word / Excel / Powerpoint. It's ridiculous... once you have 5 or more services connected... it will complain every time you open Outlook (and request a password entry for the most recently added account).
