Outlook app on iPhone is SOOOOO SLOOOOOWWWWWW!!!

The Outlook mobile app is extremely SLOW! Everything about it! Typing an email is SLOW. Scrolling through my inbox is SLOW. Using the calendar is SLOW. Going into the settings menu is SLOW. Searching is SLOW. Even typing a letter or hitting the backspace key is SLOW!

I'm using an iPhone XS running the latest iOS (13.3.1) and latest version of the Outlook app (4.30.0). I’ve tried everything...uninstalling and reinstalling the app, rebooting the phone, hard and soft reset.  I have deleted old emails to clear out my inbox...no help. This is the only app I have problems with out of about 50 apps on my phone. The phone has plenty of CPU and memory available. On my desktop PC, the Outlook with Office 365 account works perfectly fine with no performance issues. Webmail also works fine.

I opened a support case through the mobile app and was told by Microsoft they're aware of the issue and are working on a fix. THIS HAS BEEN GOING ON FOR AT LEAST 6 MONTHS!!! COME ON MICROSOFT, GET IT TOGETHER!!!

    Thanks for the suggestion.  I'm using Outlook on my Iphone on a MS365 subscription basis. I haven't found the setting you mention.

    It has been more than six months that the perfectly functioning Outlook became totally disfunctional. Slow, yes; but worse is the freezing for many minutes. Sometimes recovers but often just bombs out.

    initial activity often OK but it seems to decide life is too much and it just slows to a halt. Driving me nuts.

    Same here.

    I tried : reinstalling app

    Emptied cache memory of browser and then reinstalling app

    Took off the background refresh

    It’s a real handicap. Work is impaired.
