Access issue

For classic Outlook for Windows, try these steps in order:

1. Check whether Outlook is offline.
   • Look at the bottom of the Outlook window.
   • If it shows Disconnected, Working Offline, or Trying to connect..., go to Send/Receive on the ribbon and select Work Offline to switch back online.
   • Then try Send/Receive again.
2. If the email password was changed recently, update it in Outlook.
   • Select the email account name.
   • When the sign-in pop-up appears, select Continue.
   • Enter the new password and complete sign-in.
3. If Outlook says Please create an app password for Outlook on your email provider's site:
   • Go to the email provider’s site.
   • Generate an app password there.
   • Use that app password in Outlook instead of the normal password.
4. If the account is locked, check the account directly with the provider.
   • A locked account can prevent send/receive from working.
   • If the provider offers webmail, sign in there first to confirm whether the mailbox is accessible.
   • If the account was blocked because of unusual sign-in activity, it may need to be unblocked before Outlook can reconnect.
5. If Outlook.com is the mailbox, also check whether storage is full.
   • If Microsoft cloud storage is full, mail cannot be sent or received.

The error description send/receive error also matches common Outlook connection errors such as 0x800ccc0d, 0x800ccc0f, 0x80042109, and 0x8004210a.
