After installing iOS 18.1 Mail duplicating recipients in the "CC" line

Only seems to happen with iPad .

When I click on „Reply All“ in an email, all addresses in the CC field are duplicated. This happens with or without attachments. Have uninstalled the mail app. uninstalled and reinstall setup email.

any ideas or has anyone else seen this?

iPad, iPadOS 17

I work in IT, and many of our stakeholders, including myself, have experienced the issue you described. We use Exchange/Outlook 365, and in our case, it specifically affects individuals listed in the CC field. When you hit "Reply All," it duplicates every user in that field. As a workaround, we’ve advised some users to switch to the Outlook app until Apple resolves the bug.

For those that are experiencing this are you using Apple mail with Exchange mailboxes or just with free mail like Yahoo and Gmail? We are seeing this on Exchange mailboxes.

Was this happening on 18.1 and 18.1.1? I am on the latter.

Does anyone have a pattern? IE does the sender and the recipient on iPhones have to have the same iOS?

I send the email to other recipients and they are all seeing duplicates on their cc field. If cc 4 individuals they are shown twice on the phone.

Kinda odd that I cannot find more on this issue.
