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!!!

Using Outlook for iOS for personal email and calendar management

Definitely a MS issue, it’s their app for iOS. My iPad is where I’m having this problem most often. Their app for Android is irrelevant.
TLDR: reinstalled from corporate appstore - and it helped
Hmmm,
my corporate IT recommended that I
( - upgrade to latest iOS (which I already had been on))
strange enough: this helped, albeit I cannot tell if the reinstalled Outlook app is ANY different from the one in the Apple app store.
Just re installed from corporate App Store. Seems very quick and faultless so far. Hopefully will continue. Thanks for tip.
***UPDATE*** I think I may have found the culprit. I removed all of my shared calendars from the Outlook mobile app and it has been performing MUCH better. Previously when ever I would click on the calendar it would display “updating”. Removing the shared calendars from the mobile app did not cause them to be removed from my web mail or desktop Outlook 365 profile, thankfully.
My Issue is unrelated to clicking on the calendar. Whenever I activate the application it just is very slow in opening.
