Using Outlook for Android for personal email and calendar management
Because the problem happens on the computer, both Android phones, and the tablet, this is likely an account or mailbox issue rather than an app issue.
Try these checks in Outlook.com first:
- Sign in to Outlook.com directly and check whether the mailbox or Microsoft cloud storage is full. If storage is full, mail cannot be sent or received, and messages sent to the account while storage was full are bounced back and are unrecoverable.
- In Outlook.com, check the Other tab, Junk Email folder, and any custom folders.
- Check Filter > Sort > Date so messages are shown in normal order.
- Check whether email forwarding is enabled.
- Check whether any rules are moving or hiding messages.
- If the password was changed recently, update it. The account can also be temporarily blocked because of unusual sign-in activity.
- Use the Microsoft account sign-in helper if sign-in is failing: Open troubleshooter
For the repeated sign-in prompts in Outlook mobile:
- Download the latest Outlook mobile app version, because recurring password prompts can happen after security standards are updated.
- If the account is a Microsoft personal account, use the sign-in helper tool: Start
- If the account is a non-Microsoft account provided by another company, contact that email provider for sign-in issues.
If email still does not arrive after those checks, use Outlook.com support to reach a live support path:
- Go to Outlook.com and sign in.
- Select the Help icon.
- Search for cannot receive emails.
- Scroll to Still need help? and select Yes.
- Choose Chat with a support agent in your web browser.
When connected, provide:
- the approximate date the issue started
- examples of senders whose mail is missing
- whether those senders received any non-delivery message
Reinstalling Outlook usually does not fix a mailbox-side delivery problem.
