I need to unlink 2 gmail accounts on iPhone XR

Hi 0623190,

welcome to the Apple (user-to-user) Community!

Re: "I need to unlink 2 gmail accounts on iPhone XR :

how can I unlink personal gmail account from business gmail account"

Wondering which iOS version is installed on your iPhone,

(NB: If not iOS 16 ... for accuracy you can choose the correct version at the top of some of the articles below)

and

wondering whether you have separate GMail addresses / accounts / for business and personal eMail.

Apple support have an article online that may be helpful:

How to: Add and remove email accounts on iPhone – Apple Support

or

How to: Organize email in mailboxes on iPhone - Apple Support

Eg: says:

View emails from one account at a time. If you use multiple email accounts with the Mail app,

you can use the mailboxes list to view emails from one account at a time. (more info in the article)

Also:

If needed:

Mail support website (info. / support / contact options):

All the best :-)
