Office 365 Tial expiraiton notification problem
Apparently, we signed up for a trial version of Office 365 for Business and then forgot to convert to a paid subscription. Later, when the trial had expired and the product would no longer work, we would get a popup message about problems with the subscription which appeared to be an install issue. Later when investigating, we see that Microsoft sent an email 2 weeks prior to the trial expiration but it didn't reference the fact that it was a trial. We were working under the assumption that we had setup billing initially and thought the problems we were having were of a technical nature. So, I recommend when sending out an email notice of pending subscription expiration, you indicate that it is a trial version and needs billing setup.
