Hi everybody,
One our customer shows me the problem with new emails which is not possible to send. Web GUI say: MAPI error: MAPI_E_NO_RECIPIENTS.
After some tests we discovered when they pick receiver from address book, (double click contact to add it into "To:" field or pick contact and click "To:" button) added contacts shows "+" in front of the contact name. When I click the + I am asked to convert distribution list to separate contacts. BUT list is empty and when I confirm that I get empty "To:" field. There is not possible to add contact from address book correctly.
Server is installed on Debian13, latest community updates. We tested this in Vivaldi and Firefox browser at Windows11 and in Brave on Ubuntu24.04
