I get notifications for emails I've received, I click on the notification, and then nothing. The app opens, freezes for a second, and there's no email. And the crazy thing is I can't find it manually. I'm clearly getting emails, but somehow outlook isn't allowing me to find them at all. I see some, but definitely not all. I've looked everywhere. I don't get it.

Lately the app keeps crashing, freezing, or not being responsive. Not sure what's up because it's never done this before. Sometimes I get a message like outbook database optimizing or some dopey thing. Really frustrating. When I close the app and reopen then it works fine until I access an email, close it and then can't access another one and go through the whole thing again. I have uninstalled the app and reinstalled and then it gives me an attitude about reconfiguring emails again.

4/26/26: Another reviewer's review helped address the issue (Shane Clay, 4/23/26 review). The app is working just fine again. 4/19/26: The most recent update caused the app to keep sending a silent notification "Optimizing database" to my Galaxy S25 Ultra. Initially, I ignored it until I realized I couldn't access the app. Now, I'm logged out of my accounts and when I try to log in, I end up in a cycle of adding my email and the app crashing. I'm not having this issue on my Galaxy tablet.
