I wouldn’t be offended or consider saying anything to anyone who included this in their out of office message, but even as someone who is in a religion that forbids use of electronics on most holidays, I still think this message is 1) TMI; 2) doesn’t convey what it needs to convey unless you are explaining that you don’t use electronics during holidays, in which case you can just include that you won’t be checking email without including the religious explanation; 3) would come across to me as inclusion of personal information I don’t need, which would therefore strike an unprofessional tone,and I wouldn’t understand why you felt the need to include that info. How about “I’m out of the office without access to internet or email until (date). If you need assistance before this date, please contact…” Like I said, I think your colleagues are overreacting, but in general I would advise to leave all personal information out of your auto-reply — vacation, medical leave, religious observance, etc. — people do not need to know why you are out.
Setting Up a Holiday Schedule Log in to 8x8 Admin Console. Click Auto Attendants. Create a new Auto Attendant profile or click Edit (pencil icon) to the right of the Auto Attendant you wish to edit. Go to Business hours and select Create new schedule. Enter the Date and the Name of the holiday. If your business will remain Open, click Add business hours. Enter the Date and the Name.

Click Edit (pencil icon) to the right of the Auto Attendant you wish to edit. Go to the Call Handling Menus section and select the Holiday Open Hours Menu or Holiday Closed Hours Menu. Note: You need to select a Site for your Auto Attendant before you can view the Call Handling Menus. Select Play Audio. Click Select File. Select Call a phone number to record. Enter the Name and the Phone Number or Extension you wish to record your initial greeting on. Click Call Now and follow the instructions. Click Save.

The appropriate tone depends on the holiday. If you’re closing for Christmas or New Year’s, it’s safe to assume your customers expect you to be festive and maybe even humorous. Conversely, if you’re closed for Veterans’ day, your email should strike a more serious chord. Use our templates and double-check your tone before you hit send.
Rather than clutter your general greeting, set an auto-attendant for a campaign-specific phone number. You can assign a unique number to each of your campaigns. Record a voicemail message that helps callers to learn more about your marketing campaign.
