Start with the basics
Before you change anything, try these checks.
Small connection or app issues can look like bigger problems. These low-risk checks help narrow down what’s going on.
1
Check Outlook on the web
Sign in through your provider’s official website. If mail works there, the issue may be specific to the app or device.
2
Check your connection and service status
Open another website, then check Microsoft 365 service health if you use a work or school account.
3
Restart Outlook and install updates
Save any drafts first. Close and reopen Outlook, and install pending updates from your device’s official app store.
4
Note the exact error before troubleshooting
Record the error text and when it appears. Don’t share passwords, verification codes, or private email content.

Outlook questions, answered.
A few safe first steps for common problems.
Why is Outlook not syncing my email?
First check whether the same messages appear when you sign in on the web. If they do, confirm Outlook is online, check the account’s sync settings, and restart the app. Work or school accounts may also be affected by an organization policy or service interruption.
What should I check when Outlook won’t send or receive?
Check your internet connection and provider service status. Look for messages waiting in the Outbox, verify the recipient address, and review whether an attachment exceeds your provider’s size limit. Keep the full error text for your email administrator or provider support.
How do I troubleshoot Outlook freezing?
Save drafts if possible, close and reopen Outlook, then install pending updates. If it continues, note what action triggers the freeze. On a managed device, ask your IT administrator before disabling add-ins or changing account settings.
Is this an official Microsoft Outlook support website?
No. Inboxwise is an independent informational resource and is not affiliated with, endorsed by, or operated by Microsoft or Google. For account-specific help, use Microsoft’s official support channels or your organization’s IT team.
Can I share my password so someone can check the issue?
No. Never share your password, one-time verification code, recovery code, or remote access with an unverified person. Use official support channels and do not paste private email contents into a public form.

Getting started
How to set up Outlook
A safe setup checklist for personal, work, or school accounts.
1
Install Outlook from an official source
Use Microsoft 365, Microsoft Store, Apple App Store, or Google Play. Avoid third-party installers and unfamiliar download links.
2
Choose Add account
Open Outlook, enter your email address, and follow the provider sign-in window. Work accounts may require your organization’s setup instructions.
3
Complete secure sign-in
Approve multifactor authentication only in the official sign-in flow. Never share a password or one-time code with anyone.
4
Let the first sync finish and test mail
Wait for folders to load, send a simple test email, and confirm it appears in your provider’s web inbox too.
Practical troubleshooting
Outlook support and troubleshooting guides
↻
Outlook not syncing or inbox not updating
Check if new mail appears at your provider’s official website. If web mail updates, confirm Outlook is online and not in Work Offline mode, then restart and review sync settings. If web mail also fails, check service health and mailbox storage before changing account settings.
↗
Unable to send/receive emails or messages stuck in Outbox
Check internet access, the recipient address, offline mode, and attachment size. Try a small test message. Review mailbox quota and provider status. Confirm whether a message was delivered before repeatedly resending it.
Ⅱ
Outlook freezing, slow, or not working
Save drafts, restart Outlook and your device, and install updates from official sources. Note what action triggers the freeze. On a managed computer, ask IT before changing add-ins, profiles, or security settings.
!
Outlook send/receive errors and error codes
Write down the exact wording, code, and time. Check web mail and your connection, then consult your provider’s current documentation for that code. Do not post screenshots that expose addresses or private messages. Work-account errors may need an administrator.
⌑
Outlook sign-in problems
Use the official Microsoft or provider sign-in page. Check account status and follow the official recovery process. Never give a helper your password, recovery key, or verification code.
▣
Outlook mobile app not working or syncing
Check internet access, update the app from its official store, and review notification, background refresh, and battery settings. Compare with web mail before removing and re-adding an account.
＋
Set up Outlook on desktop, web, or mobile
Install or open Outlook from a trusted source, select Add account, enter your email, and finish provider authentication in the official window. Allow the initial sync to finish and send a test message. Follow your organization’s instructions for work and school accounts.
For Outlook latest issues or current outages, check Microsoft’s service-health information or your email provider. These independent guides cover common Outlook problems and are not live incident reporting.
