How do I access a delegated gmail account from my boss on my iPad?

Lyssa, thank you for this clarification.

For your (and doncow's) benefit, you can actually perform the "request desktop site" action from the built-in Safari browser as well. You shouldn't necessarily need to download Chrome.

To do this from Safari:

• Navigate to mail.google.com
• Tap on this symbol:
• Choose "Request Desktop Site". This may involve scrolling through the available choices.
• Proceed as Lyssa explained above.

I believe your question boils down to something like this:

"How do I access a gmail account on my iPad?"

You have two choices.

1. Set up access to this account using Apple's mail application which is supplied on your iPad along with iOS. Follow "Set up your email account automatically" and add the account as a Google account as described here. Add an email account to your iPhone, iPad, or iPod touch - Apple Support
2. Use Google's gmail application on your iPad. "Purchase" (at no cost) this app through the App Store on the iPad, and set it up.

I suggest using the first choice.

Thanks much! I use Chrome for my work-related tasks and Safari for personal stuff so wasn't sure of the steps there.

Glad I could assist!

And thanks again for shedding additional light on the Original Poster's question that I clearly missed.

You cannot do that using the Gmail or Mail apps.

What should work is this:

1) Download Chrome

2) Navigate to mail.google.com and log in with your email/password

3) Once the page loads, tap on the 3 dots and choose Request Desktop Site

4) Once the page loads, you can tap on your name/profile icon in the upper right corner to get to the delegated account.

So since it works on your desktop, as Lyssa and I have tried to tell you, use a web browser (Safari or Chrome) on your iPad to navigate to the desktop site and perform the same operations there that you successfully did on your computer.
