Hello All,

My question is Mobile brand or android version problem?

or Exchange server TLS too low security need to upgrade TLS version to higher?

Because my samsung Galaxy A52S Android 14 never set up Exchange Mail success,

suddenly Exchange Mail can't autosync.

I delete the mail account and resetup the Exchange Mail account, but still failed,
