If you go on vacation or are sick and cannot or do not want to be reached by email during this time, an automatic reply including an out-of-office note is useful so that your contacts do not have to wait unnecessarily long for a reply.
In the user settings for emails , you can set up an out-of-office note for the onOffice mailboxes that are assigned to you.
In the basic email settings, which you can access via Extras >> Settings >> Basic settings >> Email tab , you can set up the out-of-office note on the “onOffice mailboxes / external POP3 mailboxes” tab for all mailboxes located at onOffice. This can only be set by administrators.
For other, external mailboxes, please use the mailbox management at the corresponding provider.
