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!!!

    OK so I have also been having this issue for some time now.  I recently made on change that initially seems to have greatly increased the response time of the app, especially the calendar option.  Under settings in the Apple iOS, i went into the app settings and changed location from ask each time to never.  This seems to have removed 98% of all my lag issues with the app.  Hopefully it can be this easy for others as well :)

    I concur. Even trying to navigate the app's settings is so latent, I can barely click the items I want to target.

    Each swipe, scroll, or tap is on about a 2s (that's 2000ms) delay. It's awful UX, imo. Please fix this.

    iPhone 8

    iOS 13.3

    Yes you are absolutely right. It was working fine in a certain version, however, as you rightly said, each update is making it worse. I have an iphone 11 pro and running the 4.45.0 version of the outlook app. Everything is so laggy. However I don’t have any issues on the ipad app. This is making it extremely painful to use the app. I am planning to start giving this app a one star review on app store and collectively ask my friends to also do the same. Hope Microsoft dev team wakes up at least then.

    I have not tried a back of the device, we did make them just in case, but didn't restore as everything we do is hosted in the cloud or making calls to one of our database servers.

    The difference in the reset is that it just wipes out the user information, installed apps, and reboots to start over. More like creating a new profile on a desktop vs reinstalling. The recovery from iTunes however, downloads the complete image clean from Apple, iOS, the firmware, etc. It does a hash check at download and unpack, then does another verification after it install the firmware and iOS.

    The way I understand the iOS back up with iTunes is that it saves all your preferences and files, NOT the apps. You will see the little down arrow on the icons, tap on that and it will redownload the apps to complete the install. Outlook should only retain its settings. It will redownload any emails based on your preferences. We tend to only store 1 weeks worth on the devices but allow the user to adjust based on their needs.

    We do not have any other reported slowness issues to test this approach though.

    So I got my hands on one of out field teams iPad after swapping them over to a new known and confirmed working iPad.

    Removing and reinstalling the apps using Intune did not resolve the issue (We use Intune to manager all our mobile devices and apps from a single pane of glass). But I was able to figure out a solution that we have now repeated 6 times.

    We did a full on recovery of the devices using iTunes. not using the factory reset on the device. When we did the reset on the device the issue remained. Once the recovery process completed, we signed back into Intune and allowed all our apps redeploy. (Word, Excel, Outlook, Powerpoint, Teams). And from there everything has been smooth with out issues 4 weeks and counting.

    So again. Recovery Mode, iTunes on the computer, restore and update = Happy iPad and Happy user.

    This leads me to believe a bad update happened at some point to these devices and all future updates did not correct the issue.

    Hi PatrickBehm - Glad to hear you made progress! Thanks for sharing the update. I have a couple questions...

    For those of us who don't use Intune, I wonder if it would suffice to back up the iPad/iPhone to iTunes, wipe the device, and then restore from the backup. Or would it be necessary to factory reset the device followed by a complete fresh iOS install?

    What is the difference between iTunes "recovery" vs "Erase all content and settings" on the iPad/iPhone itself?

    It seems like the iPad/iPhone is retaining is old/bad data from a previous version of the Outlook app. It also seems like restoring from any backup, whether it be iTunes or iCloud would bring back that old/bad data. Hmmm.....
