I guess I generally dislike ones where the person is actually around but just might take longer than usual to answer emails (except in public-facing inboxes, etc.) I understand that if I’m using email, you might not respond right away.
Yes, I phoned a dentist office late in the day for a reinfected root canal problem and got a cutsy “humphrey bogart” fake reply on their voicemail — I thought it was extremely inappropriate for a business office to use something like this. It was hard to find it funny, especially because while calling me “sweetheart” and all that, the message didn’t actually tell me when they might return my call (later that day? Next day? Next week? Never?) nor did they offer any options for emergency contact with another dentist.

While you’re writing and activating your out of office message, avoid including the following:
The announcement of holidays to the employees should be done in a professional and formal way. One way to do this is to write a memo and send to all the employees to inform them about the upcoming holidays and closing of the office. The other way is to write the letter and send it to each employee individually.
