To set up an Outlook email account, go to outlook.com or open the Outlook app. Click 'Create free account' if new, or sign in with your Microsoft account. Enter your name, desired email address, and password. Verify your identity via phone or email. Once confirmed, customize settings like time zone and privacy options. Save changes to start using Outlook.

To sync your Outlook calendar, ensure all devices use the same Microsoft account. Enable 'Sync' in Outlook settings. For mobile, download the Outlook app and sign in, selecting 'Calendar' sync. On Windows or Mac, log into the desktop app and check 'Calendar Sync' under account preferences. Alternatively, use IMAP/SMTP settings for cross-platform access.

If Outlook crashes or won't open, restart your device and update Outlook via Microsoft Store or AutoUpdate. Run the 'Outlook Safer Mode' by pressing Windows + R, typing 'outlook /safe'. Repair installation through Control Panel > Programs > Modify. For persistent issues, disable add-ins or scan for malware using Windows Defender.

Create folders in Outlook by right-clicking your inbox and selecting 'New Folder'. Name the folder and choose a location. Drag emails into it, or set rules via 'File' > 'Manage Rules & Alerts'. Use categories by right-clicking emails > 'Categorize' to assign colors and labels. Regularly archive old emails to maintain organization.

Share your calendar via the Outlook web app or desktop. Click 'Calendar', right-click the calendar name, and choose 'Share' > 'Calendar Permissions'. Enter the recipient's email and set permissions like 'Can Edit' or 'Can View'. Send the invitation. Alternatively, publish the calendar by selecting 'Publish' to get a link for sharing externally.

Set automatic replies via Outlook desktop: Go to 'File' > 'Automatic Replies'. Enable it, set date range, and customize messages for internal and external recipients. Save settings. On web, access 'Settings' > 'Mail' > 'Automatic replies' to do the same. Test by sending an email to yourself to ensure it works.

Import contacts by exporting your existing contacts to a CSV file from Gmail or iCloud. In Outlook, go to 'People' or 'Contacts' > 'File' > 'Open & Export' > 'Import/Export'. Choose 'Import from another program or file' and select CSV. Map fields to match Outlook columns, then finish the import process.

Use the search bar at the top: Type keywords like sender name or subject. Refine with filters like date range, size, or flags via 'Search Tools' > 'Advanced Find'. For faster results, create saved searches by right-clicking the search icon and setting criteria. Keep your mailbox indexed through Outlook's indexing options.

Enable 2FA via your Microsoft account: Sign in at account.microsoft.com, go to 'Security' > 'Advanced security options' > 'Add a new way to sign in or verify'. Set up an authenticator app or phone number. Verify codes when prompted. In Outlook apps, you'll need to enter this code after your password during sign-in for added security.

Recover emails from 'Deleted Items' by right-clicking and selecting 'Restore'. For permanently deleted items, go to 'Deleted Items' > 'Recover items deleted from this folder'. If unavailable, use 'Recoverable Items' via web app under 'Trash'. For corrupted accounts, run Outlook's recovery tools like 'ScanPST' to restore data from backups.

Create rules in 'File' > 'Manage Rules & Alerts'. Select 'New Rule' and choose conditions like sender or subject. Set actions like 'move to folder', 'flag', or 'delete'. Test rules with samples and save. Use folders to keep organized; examples include moving newsletters to a 'Read Later' folder or archiving old emails automatically.

Resolve IMAP sync problems by verifying server settings: Ensure incoming IMAP port 993 and outgoing SMTP port 587 with SSL encryption. In Outlook, go to 'File' > 'Account Settings' > 'Change', and update details. Clear cache via 'Control Panel' > 'Mail' > 'Data Files' > 'Clean Up'. Restart Outlook and test sync.
