We have about reached the end of our patience with the reliability of the hosted Exchange part of Office 365. If it isn't fixed soon, we will either dump the service and go with an internal Exchange server, or go with a competitor's solution. Microsoft tech support has not been able to solve the issue, which has been going on for about a month now and they seem unwilling to escalate the issue.
The issue is that Outlook keeps prompting most of our 87 Outlook users for the Exchange account credentials, and there is no pattern to it. Some never get prompted, some get prompted more than once a day. On some days, IT is constantly running around putting in the credentials (due to all the issues, we have not let them pick their own yet). We do not have an ADFS, as this is identified as an optional item, and have no plans to implement one.
The odd thing is that the reliability issues started about 90 days after we had gone live with the service, after a successful trial of the beta with a limited subset of users. When the passwords started aging out, we found that Office 365 does an extremely poor job of informing the user that their password has expired. We have also found that some user's passwords stop being accepted by OWA for no apparent reason, forcing us to reset the passwords on those accounts.
IT's reassurances that this is a new service and MS is going to fix it is wearing thin with our CEO and Exec VP, who is not a fan of Microsoft in the first place. So, my question is, what is it going to take to fix this?
Ok so without ADFS you are using online accounts and this post has information about the Password policy for online accounts, community.office365.com/.../office-365-password-policy.aspx
What version of Outlook are you using? Have you run the "Setup and Configure your Office Desktop Apps" from the download page on the Portal?

The password policy is not the problem. The issue with continually getting prompted for the password was triggered when the passwords expired at the default period of 90 days. In the meantime, MS tech support provide us with a script to change the pw policy so that the passwords never expire, in an attempt to sort out what is going on.
FYI, Office 365 comes with Outlook 2010 Pro.
No, resetting the password fixes the issue, for a while. It will run fine for a day, or several days, then Outlook will ask for the password again. Sometimes, reentering the same password will restore operation, sometimes it will not. When it doesn't, we reset the password again and enter it into Outlook again, it works and the cycle starts over.
This happens even though the 'save password' box was checked when we entered the new password. If the 'always prompt' checkbox had been checked, it would prompt for the password everytime, and it does not do that. One interesting clue is that a number of the Outlook accounts now have a different Exchange server in the account settings than the one that we were originally given by Microsoft. It seems as though the account information is not being accurately replicated between the clustered Exchange servers, but our level 1 support guy doesn't seem to have a way to verify that. The issue is compounded by the fact that we can't get anyone on the phone right at the time the issue is occurring. We could take a Wireshark trace, if that would help.
Note that it has not be established with certainty whether the issue is on the Exchange side, or the Outlook side. Since the password is encrypted, MS would have to have a way to decrypt the password that Outlook is using in a failure case and read it back to us to verify that Outlook is remembering the correct password. Restoring operation by re-entering the same password is an indication that the issue in on the Outlook side, but is not conclusive because that act may 'refresh' the authentication cycle. My suspicion is that the issue is on the hosted Exchange side, but in any event, the authentication mechanism is not reliable.

We have been using the OWA logon to troubleshoot in the way that you suggest, if the known/current password does not work in Outlook. In all but a couple cases, when the password did not work in Outlook, it did not work in OWA either. Like I said, the issues started occuring when the passwords started expiring. We also ran into an issue on Monday where all computers prompted for the Outlook password after a Windows Update reboot. In this case, the password field in Outlook was blank, but entering the known password restored operation.
Yesterday, Office365 tech support provided an update to the signon assistant component that is now supposed to inform the user that their password has expired and give them the means to change it. We will be testing that and pushing that out when we can. In the meantime, the issue seems to have died down even though we made no changes on this end, other than pusing Windows and Office 2010 updates. The only one that had to be entered yesterday was for an employee that had not logged on since last week, so we are going to wait and see.
Thank you for your reply and updating the status of the issue.
The original issue disappeared after installing Windows and Office 2010 updates. You have updated Microsoft Online Service Sign In Assistant and will wait for several days to check the results. Given this situation, if you have any other questions regarding this issue, please do not hesitate to contact us. It is always our pleasure to be of assistance.
I did all that, and my Office is up to date with patches. I still get prompts for passwords.
I am also having the same problem. My password is accepted fine by Sharepoint, web outlook, mobile phone, etc. Only Outlook seems to have the problem. It is sporadic in that it will work fine for a couple of hours, then prompt for password and get stuck at trying to connect. If I close out and go back in it will work fine for a while, then prompt for password again.
I understand that you are prompted for credentials when using Outlook. At this point, you can try to troubleshoot this issue referring to http://support.microsoft.com/kb/2637629.
If the issue persists, I recommend creating a new dedicated thread for this issue, so that we can dig deeper on this issue. Thank you for your understanding.
I'm dealing with the same issue but on a Mac. Sometimes (very rarely) I can keep on working for a few hours but all of a sudden, the system keeps on prompting time after time asking to reenter my credentials.
Pleas keep us posted !
My problem is specific to the account associated with Office365 and started when we started the migration from Online services to Office365 so I'm not sure how it is any different from the issue reported here.
From your description, I suggest refer set up the desktop for Office 365 to see if it works.
For tips, if you have installed or don’t need Lync 2010 and Microsoft Office Professional Plus for Office 365, you may skip steps 3 and 4 of the article above.
In addition, if you need further assistance on the issue, I sincerely suggest post detailed information about the issue, such as some screenshots, in a new thread in the forum. This is so your question will be answered quickly.
Thanks for understanding,
From the description, I suggest check and install the latest update of the current mail client, such as Outlook 2011, on your MAC to see if it works.
In addition, if you need further assistance on the issue, I sincerely suggest post detailed information about the issue, such as MAC OS version, Outlook client version and some screenshots, in a new thread in the forum. This is so your question will be answered quickly.
