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!!!

    Haha. Reduce the data if it is an option? Shouldnt they know of this is an option on their broken app?

    I highly doubt that the large data set is the issue. We have multiple new users with in our organization with newly created accounts and new ipads & iphones all having this issue. It is not consistent either. One might have an issue on their iphone but not their ipad. Or they might have the issue on both. We have wiped the devices. Removed and re added them to our Intune portal for management. Manually loaded the apps vs having them pushed. The problem persists. It is not related to cellular data either. Same issue on wifi even if we remove the SIM cards.

    Lots of frustrated field personal who are being slowed down as this seems to be for ALL microsoft apps not just Outlook

    same issue here, any fix?

    edit: restarting account seems to help but only temporarily.

    Thanks for the update. I deleted more old emails and got my account down to 1.5Gb used out of 5Gb. It’s no better. I believe it’s more so affected by the number of emails, calendar events, etc. My next step is to go back and delete old calendar events from years ago. Interesting find someone else mentioned...if you turn on airplane mode it works great. Scrolling through the inbox (or other email folders) and the calendar is peppy again...Except for the fact that you have no internet connection. Obviously not a fix but from a troubleshooting standpoint the app is trying to communcate with the server to load something, but is struggling. I have background app refresh enabled for the outlook app which I thought might help but NOPE! No matter how long it has had a chance to sit snd catch up with downloading its still very slow. I wish I could go back to the native IOS mail/calendar apps but unfortunately my organization doesnt allow it.
