The IT Center is updating Office 365 licenses, and, unfortunately, it seems that after the update, messages sent to a user will not get through, but are returned to the sender. This is resolved as soon as the user logs into his email account after the update.
The problem also affects reminders and pick-up notices sent by the library, if you have a helsinki.fi email address in Helka.
If you have loans or requests, please monitor the situation in Helka. The updates will continue during week 13 ( 25.-29.3.).
We are very sorry for the inconvenience.
