The Kolab skins

Posted on: September 11th, 2023 by

Some users probably remember when we first released the new Responsive skin back in 2018. Since then, the responsive skin has been developed further, some improvements were made, and the skin was promoted to be the default skin for new Kolab Now users.

We in the Kolab Now team love the Responsive skin, and we were not going to miss the old static skin when it was not deployed during the update to the latest version of the webclient. We had only received positive feedback about the responsive skin so far, but it turned out that some users still were very fond of the old look and feel.

Incident report: “Stability!”

Posted on: September 1st, 2023 by

Welcome back!

Service window postponed – Due diligence..

Posted on: June 23rd, 2023 by

Last week we announced a service window that was supposed to start and be in session about now.

The operations that are going to happen are on the backend servers, are quite sensitive, and we would like to avoid any problems. We therefore suspend the current service window and hereby declare it for the coming Friday:

Friday 2023-06-30 at 08:00 UTC until 13:00 UTC.

How to prevent deleted e-mails from disappearing permanently

Posted on: March 27th, 2023 by

Last week our support team reported interestingly some similar questions from unrelated users circling around the topic: “I accidentally deleted some e-mails. Can I get them back?”
