I'm getting questions from people looking for help with Outlook after upgrading to iCloud 3 (or newer). It seems that after installing and configuring iCloud, they can’t send email from Outlook using their iCloud email accounts: a box keeps popping up with the outgoing server string and asking the user to enter their username and password. Some users also report receiving error:
0x80004005 - cannot synchronize subscribed folders
This is caused by a bad server configuration in the iCloud setup. Apple changed the server configuration - the following server names should work, not the names that begin with p00 (where 00 is any 2-digit number).
In Outlook 2010 and newer, look in File, Account Settings, double click on the iCloud account to open the Change Account dialog.
The first page will have the server names. Use smtp.mail.me.com as the SMTP server name and imap.mail.me.com for the IMAP (incoming) server name.
Account Settings
The following are the account settings entered on the first page of the account setup dialog.
| Field | Setting |
|---|---|
| Account Type | IMAP |
| Incoming server | imap.mail.me.com |
| Outgoing Server | smtp.mail.me.com |
| Username | alias |
After checking (or completing) the account setup dialog, click More Settings buttons. On the Outgoing Server tab, select:
- My outgoing server (SMTP) requires authentication
- Use same settings as my incoming mail server
On the Advanced tab, set the port numbers and select SSL/TLS:
- Incoming server (IMAP) Use port 993 and enable SSL
- Outgoing server (SMTP) Use port 587 and enable TLS (select TLS first, then change the port number)

after adding icloud to Outlook 2013 (desktop), both calendar and contacts are added to my Outlook and it seems to be working. Able to sync the contacts and calendars from iphone to Outlook is all I want to do, and I don't want to sync the emails. But now sending and receiving emails from Outlook get the error msg " 0x8004010F Outlook data file cannot be accessed." even the Outlook data file is the default. And I checked the Outlook profile, everything seems to be ok. iCloud add-in is also installed. But I am not using icloud email. What should I do to fix the problem?
Diane Poremsky says
This page applies only to Apple email accounts, not to icloud sync. Do you have the newest icloud software? There is a known issue with the icloud addin that prevents mail from being sent. Make sure you have the latest version of icloud - i think it's version 5.2 by now.
You can try signing out of the icloud utility and signing back in.

Dear Diane
Thank you for your reply!
And sorry for posting my problem to the wrong community.
My problem is solved now.
Best Regards,
Diane Poremsky says
Do you know what fixed it? It might help others with the same problem.
Susan F says
thank you so much for this fix. I purposely avoid updating software because of these glitches costing me a few days of functionality; your site/knowing someone is keeping up with the glitches and offering fixes may be what gets me to update more quickly.
Paul Stanley says
I tried to look up everything about fixing my email - it wouldn't send from the Outlook Outbox. I changed "25" for "287" and it worked finally!!! Took days to find this...
Shaquay Selby says
This hasn't worked for me. Could you please help?
Diane Poremsky says
Do you get a send and receive error message? Changing the port and server names as shown on this page *should* work but its possible there is something else causing your problems.

Thank you!!
Kat says
The trick was deleting the p26 out of the server settings. this helped! thanks!
Shaquay Selby says
Where would I find p26? Could you walk me through?
Diane Poremsky says
Assuming Outlook 2010 or newer, it's in File, Account Settings, double click on the iCloud email account and change the server names.
Mike B says
Thank you you genius - been nearly blowing my brains out trying to find out why my e-mail send stopped working. Your solution worked a treat

Hi, I have a similar problem, using POP3. The message I get is "Microsoft Outlook could not complete the operation. One or more parameters missing". The emails don't go to the Send box. They just don't send.
I turned off iCloud as soon as I found the problem but it hasn't helped.
Nigel Palmer says
I have the same problem but with POP3 not IMAP (which I don't use). If I disable the iCloud Outlook Add-in, I can send mail. But of course then lose synchronisation with calendar etc. So at present I send an email which stays in Outbox. Then disable the Add-in. Open the email from Outbox and press Send again and it goes. Then reverse this to get the sync back. This is on a brand new PC. Any ideas?
wing tam says
my outlook suddenly cannot send mail. I was using smtp.mail.me.com for almost one year.
I read this forum and change to p06-smtp.mail.me.com and it work again.
thank you for solving my probelm which annoy me for three weeks....
The Gooch says
A problem that I had was when I clicked "send mail" and l got the "could not complete the operation.." error. I created a new default mail profile with 2 pop3 accounts. Afterwards I re-configured iCloud to sync with Outlook, and now it works perfectly,
Margaret Storti says
Most are stuck. The odd one here and there go out but most do not.
Margaret Storti says
I am having problems of stuck outgoing email in Outlook 2007, which started right after I installed iCloud (around 9/26/13). Incoming mail seems fine, but I cannot figure out how to fix this. Will your solution listed above work for this earlier version of Outlook? All my Windows 7, Microsoft and iTunes files are up to date, but this is exasperating.
Diane Poremsky says
It may work. Do messages not send at all or do they send if you avoid looking in the outbox? I know iCloud will mark messages read if you look in the outbox - and this prevents messages from sending.
