Using Outlook for Android for personal email and calendar management
No information provided in this reply is helpful and is general knowledge to 99% of users these days. Turn it off and on, restart, reinstall, go and look elsewhere for a solution. This is clearly a real issue being ignored by Microsoft. The Outlook for Android support link provided is anti-help.
To Microsoft: Just fix the issue. Same notifications for the same emails sometimes more than once a day, so ill have 5 new emails in the morning, then get other emails throughout the day and receive additional notifications for those same 5 previous emails from earlier that day, then in the afternoon ill get an email and get new mail notifications for the entire days worth of emails.
Ive reset imap accounts, I've re-installed, I've re-started. I've re-everything'ed. Stop providing the illusion of advice that was new and relevant for users 20 years ago and try to assume that your users have what is considered by today's standard; basic technical knowledge, or have already sought that information else-where and are here for a resolution of what should be acknowledged as a technical fault.
Fix it.
