I receive a not implemented error report when trying to send or receive emails

Dear Tarsh Rodda

 

Welcome to Microsoft Community.

Based on your description, I'd like to check something with you first:

1. What is the mailbox extension you are using? (Outlook/Hotmail, Gmail, Yahoo)
2. Is your mailbox for company/school use or personal use?
3. What version of Outlook do you use and what version of Office is it associated with? (M365, 2021.2019)

For your question, I hereby suggest you to try the following to confirm if you can solve the problem:

View offline mode:

Within Outlook in use, click Send Receive to view offline items and unclick.

Verify that the network is working:

Test whether the network is working properly by using a browser, etc., or try to switch to another network.

Repair and reinstall Office:

Click Start>Settings>Applications>Installed Applications, find Microsoft Office and select “...” Click Change, select “Quick Repair” or “Online Repair”, then follow the prompts to operate, if it fails, follow the above method to find Office, select Remove, restart your computer and re-download and install it again after completion.

Disable plug-ins:

Sometimes plug-ins can cause problems. You can try to disable all plug-ins and then enable them one by one to find out the problem plug-ins.

Open Outlook and go to File > Options > Add-ins.

Select “COM Add-ins” in the “Manage” drop-down menu and click “Go”.

Uncheck all add-ins and restart Outlook.

Reconfigure your account and create a new Outlook profile:

Within Outlook, click File, select Account Settings, select Account Settings, reconfigure mailboxes and confirm recovery. If it does not work, click File, select Account Settings, click Change Profile, restart Outlook, select Options, select New, enter a new name and click OK, then follow the screen prompts to re-add the mailbox, when finished, continue to click Change Profile, restart, select Use New Profile in the window and click Confirm.

In the meantime, you can also follow the following ways to communicate with Microsoft's human customer service:

1. Click the link.–Contact - Microsoft Support
2. In the box under “We're here to help,” enter Outlook, click Get Directions, and then click Contact Customer Service. (You must be logged into your Microsoft account. If not, follow step )
3. In this section, you need to sign in to your personal Microsoft account.

Note: You can only sign in with your personal MSA, when you sign in with your company account, it will not display correctly. If you are unable to connect to this account, you can use another account or create a new account to manage it.

4. Under “Products and Services”, select “Other Products”, select “Outlook”, and then click Confirm.
5. You can select “Chat with a Support Specialist in a Web Browser” and go to the chat window.

Note: Please contact us during local business hours on weekdays, CHAT is not available 24 hours a day. 

Feel free to text back if you need further help.

Best wishes
