Using Outlook for Android in business environments for email and scheduling
Possible fix?
I'm using a Samsung S10e, noticed I hadn't had any email notifications since last night (appx 17 hours ago), opened the app and there were a dozen or so emails received unnotified.
Tried restarting the phone and checking for updates; neither worked. Already set to 'Show notifications'.
Tried adding Outlook to 'Never auto sleeping apps' (even though Outlook was not listed under either 'Sleeping apps' or 'Deep sleeping apps'); got an email notification through on the very next email!
Possible Fix Instructions:
Settings>Battery and Device Care>Battery>Background usage limits>Never auto sleeping apps>+ symbol>Outlook>Add
Hope this works for you/stays working for me!
