Yet another day where I get to update apps on my Android phone. Except that is, the Outlook for Android app. No recent updates means no fix for this problem.
I am stuck at version 4.2307.4. This is the most recent version that does not - at least for me - exhibit this behavior where syncing to the Android calendar is disabled without user intervention.
I am very thankful I do not have to use Outlook for Android for most of my email. However, my employer makes this app the only means by which I can get work-related email and access to my work calendar from my phone. And this syncing problem means I cannot reliably view my work calendar with the calendars for the rest of my life.
My experience with Microsoft's competitors is far, far better. I use AquaMail for my email. Its feature set is far superior to Outlook for Android. HTML signatures, unique signatures for every account and email alias, flawless synchronization. . . an overall superior UX with much, much better customer support.
My calendar solution is Calengoo, which I find has the best notification management of any calendar app running on Android. Again, great customer service, especially compared to Microsoft.
What I wouldn't give to not have to use Outlook for Android.
