Outlook 2010 - can't send emails but can receive emails

I am using Outlook 2010 and periodically for no apparent reason I can't send emails
although I can receive them. The error message I get is '0x800CCC80 none of the authentication methods
supported by this client by this client are supported by your server'

I have tried various solutions I found on line but no success.

Normally the problem goes away up to a week later but clearly I can't keep having these interuptions.

I have ticked 'My outgoing server (SMTP) requires authentication' and have set it to 'use same settings as my incoming mail server'

Don't know what else you need to know?

I did appreciate the any recipient from your earlier post ... I was not aware of the scope for all recipients ... i.e. all in teh one domain but taking it as anyone in the world (ish) then that wouldn't be relevant.  Do you know of anyone else using the same provider, (away from your organisation) ... and see what they experience.

It doesn't sound as though you are using exchange therefore if it works generally and goes away of it's own accord then I would say it is unlikely to be your outlook client at fault.  Looking at the highest risks from my perspective:

1. If it affects all recipients then perhaps your provider and
2. if a specific address then perhaps their provider.  

Have you tried sending from any other pc and/or domain and 'validate the time factor by using the suspect pc before and after the alternate method?

Thanks Chris

It affects all recipients

My provider claims it is nothing to do with them (their servers) and must be a problem with my settings.

Not sure what you mean in your last para - you mean set up this email account in outlook on another PC and try that as a test

but what do you mean by ''validate the time factor by using the suspect pc before and after the alternate method"

I don't understand how it suddenly stops working and eventually corrects itself - I don't change settings, PC is not turned off - very odd

I've tried sending from the same account on my iphone and it doesn't work on there either

The email is not sent and I get a message that says

'A copy has been placed in your Outbox. Verify that you have addressed this message correctly. Check your SMTP server settings in Mail Preferences and verify any advanced settings with your system administrator'

As the settings on my PC and my iphone have both worked in the past and now neither do - surely it is something to do with my provider despite what they say?

Or can you suggest any other ways that I can resolve this please?

Sorry, basically I was wondering if when it fails another PC could send emails to the same recipient, and that if so bracket that test with a send from the duff PC before and after. i.e.

Test send duff PC
Test send alternate PC, (same recipient)
Test send duff pc.

I don't think the Ipone send will relate as it presumably uses the same POP settings ... or are you using a mail server for example exchange in your organisation).

OK

I can't do this as I don't have access to another PC with Outlook 2010 to try and replicate what is happening on my PC

Yes settings on my PC and my iphone are the same

As far as I can see if the two devices have the same effect then by virtue of the different hardware and application it has to be the provider .. but as for evidence to support it I don't know :o(.

Whilst there are workarounds, have you considered adding another pop account with a different provider, (google mail springs to mind) which at least has the potential to add another sending mechanism for when you have the problem.

As part of pointing the finger at your provider ... can anyone else send to the recipient when you are having the problem?

I can't send to ANY recipient at all - including for example recipients I regularly send to from my work email account

I'll try the provider again thanks for your help

As much as I appreciate the closure, di dyou confirm the provider was at fault or do you still have the concern?
