In a community, we all have responsibilities, and in a working environment it is each of us duty to inform our fellow about our missing office time. Using an out-of-office note denotes also your respect towards you co-workers.
So, I want to share with you my favorite out of the office note:
Hi there,
Thank you for your message. I am currently out of office, with limited access to e-mail. I will be returning on <date here>.
In case you need assistance before then, you may reach me at <phone number here>.
