Forwarding UMail

As of January 2026, UMail doesn't allow any forwarding any more, not even to domains like strw, physics and lorentz (and probably not even for those people who have applied for an exception). So all of this information is obsolete.

However, redirect rules were not automatically disabled, so users will have to do that themselves to prevent loosing mail. Basically, follow the steps in this PDF to find your existing rule, and remove it.

So, from now on, users should be aware that they have two mailboxes (institute and ULCN) and check both of them in order not to miss any important mails.

===== Old info, to be removed ===== In the weekend of May 2,3 all uMail mailboxes for guests and employees have been transferred from Open Xchange to MS Exchange. This effectively disabled your forward settings for the UMail mailbox. So you have to setup forwarding (again). A ISSC helpdesk information page is available in the ISSC helpdesk. But we have made available these instruction directly in this PDF. ====If forward/redirect does not work==== It is extremely important that you do not skip the 'Adding the forward address to your contacts' because your institute email address is considered by Exchange as an 'outside' address and for that reason you need to create a contact which points to you at your institute mail address. For those who 'cannot find' the 'waffel'-menu. It is the little 3×3 matrix of squares in the top left of the panel: Further details on how to create the contact are in this PDF. In the redirect rule you choose this, just created, contact as the address to redirect to. If you find the order of the rules confusing: first the delete rule, then the redirect rule, you must accept that it does work as expected: first do the redirect, then the delete. It is just one of those MS interface features… One more note: If you are testing the forward, please do not mail from the email address to where the uMail forwarding points. It is an Exchange feature to not forward back to the same address, as this might create an infinite loop. Test the forwarding from another email address.
