I should have specified that I’m using Fairphone OpenOS, i.e. I’m attempting to be Google-free.
I tried again to remove my old Exchange account and realised that it was possible to click on the account email address, which finally took me to a screen where I could remove the account. The steps were:
- Settings > Accounts > Exchange
- Click on account email address (where it said ‘sync error’)
- On the Sync page, click on the three vertical dots in the top-right to open that menu, and select ‘Remove account’.
Thanks for your help and advice, @Roboe and @Patrick1 - it encouraged me to persist in looking for the solution! @Patrick1, simply not syncing my old account wasn’t an option, as I couldn’t attempt to set up a new account until the old one was removed, because they shared the same email address.
Unfortunately, even having removed the old account it’s not possible for me to set up a new Exchange ActiveSync account using the native email app on Fairphone Open OS 6.0.1. When I try, the Email app crashes with the message ‘Unfortunately, Email has stopped’. This problem is reported by many people here: Exchange account. E-mail application shuts down, and the issue documented here: https://bugtracker.fairphone.com/project/fairphone-fairphone-os-android-6/issue/93. I’ve resigned myself to using the Outlook app for now
