Using Outlook for Android in business environments for email and scheduling
I can confirm that. IMAP is completely broken by the latest update 4.2039.2 from October 9. Reinstall won't help. There are similar reports in Google Play reviews and Reddit post.
Steps to reproduce:
- add IMAP account including ports 993 and 587
- go to launcher main screen
- send an email message from another device
- notification is shown and email received in Inbox - ok
- close the Outlook from task list (or restart the phone)
- start it again
- you'll notice a short message "messages and calendars are updating ..."
After that the IMAP account no longer works. No new email notifications and the Inbox is usually stuck with "getting new messages". Account reset won't help either.
Microsoft, do not try to blame the email provider nor the settings. It is your bug, fix it.
