Theia supported a change of email senders in Microsoft 365, retaining existing receiving addresses and sign-in names.
BikeDays.ch / Cycleweek
Events & Sport
A new email identity affects more than the sender shown on a message. For BikeDays.ch / Cycleweek, Theia supported the switch of the agreed mailboxes to @cycleweek.ch in September 2026. The existing BikeDays addresses were retained for receiving email. Sign-in for existing users was also considered separately.
Cycleweek needed to appear as the sender in everyday email communication. At the same time, the existing @bikedays.ch addresses were still familiar and needed to continue accepting incoming messages. Both requirements had to be considered during the change.
There was also a practical question: does changing an email address also change the name employees use to sign in? The customer specifically asked about this after the change. Explaining the different addresses was therefore also part of the support.
Theia changed the default sender addresses of the agreed mailboxes to @cycleweek.ch. The existing @bikedays.ch addresses were retained as additional receiving addresses. Outgoing mail therefore used the new identity, while the previous contact addresses remained configured.
Theia left the existing users' sign-in names unchanged. In the subsequent correspondence, the customer was informed that the new default sender address did not mean a change to the existing sign-in name.
The scope of this step was clearly defined: info mailboxes were excluded from the change. The work was carried out as part of ongoing Microsoft 365 support and coordinated with the customer.

Theia supported Superlab Suisse Epalinges in introducing Dynamics CRM and creating a custom dashboard. Another specific contribution followed when responsibility for the CRM changed: we transferred the licence and assigned the existing records to the new user.
VALUEworks uses an on-premises CRM based on Microsoft Dynamics in a family-office setting. Theia has supported the application for several years. Day-to-day work includes specific questions about mandates and reports, as well as assessing the changes the team would like to make.
Which emergency dental service covers a region, and when does the service change? To access this information, AERZTEFON needed an interface to Apollonia, the solution used by SSO Zürich. Theia implemented the technical connection and coordinated the API with AERZTEFON's development team.
