Is there a way to have the mails deleted in Outlook after reading them on the phone in the mail app and vice versa?
I have the following setup:
Huawei-Android - T-Online-Account - MS Outlook Desktop 2019
You should be able to do this in the settings
Should? XD So you suspect it, but you don't know, right.
No, I know that it does that for me, but I stopped it ages ago, back then it was in the settings and that's why I should say
