Set an Out Of Office Reply for my Email Account

Open your Gmail account in a web browser.
Click on the gear icon in the upper right corner of the screen and select "See all settings."
In the settings menu, click on the "General" tab.
Scroll down until you see the "Vacation responder" section.
Click the toggle button to turn on the vacation responder.
Set the start and end dates for your vacation, and enter the subject and message for your out of office reply.
If you want the out of office reply to be sent to everyone who emails you, make sure the "Only send a response to people in my Contacts" box is unchecked.
You can also choose to limit the number of times the auto-reply is sent to the same person by checking the box next to "Limit to once every" and choosing a time frame.
Once you have finished setting up your out of office reply, click "Save Changes" at the bottom of the page.

Your out of office reply will now be activated and will automatically be sent to anyone who emails you during the time frame you specified. Make sure to turn off the vacation responder once you return to work.
