We have an Outlook 2007 client who was able to view my shared calendar until

a couple of days ago. Since then the client prompts for a User Name and

Password that always fails (double checked correctness by logging into It fails three times then returns the message

Cannot verify or add the calendar to Outlook. Make sure the following link

is a valid calendar link:

webcals://<the url to my ICS would be here
OK button

Does anyone know how to fix this?
I tried to share my calendar with another coworker and neither is able to add

my calendar to their Outlook with the same details as my previous post.

So I deleted the 2 email addresses showing in my "Publish to Internet" -
"Change Sharing Permissions". Then I did a "Publish to Internet" -> "Share

published calendar" and sent the email to both coworkers.

Same result. They can't click on the email "subscribe" and successfully add

it to their calendars.

Both coworkers have valid Live ID accounts for the email address i sent them.

Any ideas?
I am having the same issue. One of our users suddenly started getting prompts

to sign in for all of our shared calendars, and they wouldn't go away. We

deleted her calendar and reinstalled it, her calendar is now published and

visible through the Office Online site.

But, now when she tries to share her calendar with the rest of the team, we

are not able to subscribe to it. We all get the "Cannot verify or add the

calendar to Outlook. Make sure the following link is a valid calendar

link:...." error message.
I and two other users are having this exact same problem so we deleted

everything to start over even creating new iCal publishing accounts. We can

publish but we can't subscribe to another's published calendar due to the

"Cannot verify or add the Internet Calendar in Outlook. Verify the link is a

valid calendar link:" error.
Microsoft has acknowledged a problem with publishing and has listed some work arounds.
Thanks for the quick response!

In my case my client has a GMail account and a Google apps account. I can add the GMail account's calendar to his Outlook 2010, no problem. But trying to add the Google apps account's calendar in the same way generates the Outlook can't add or verify error. I've even made the Google apps account calendar Public and the problem still occurs.

The solution should be obsolete as they made a lot of changes since then. What exactly happens?

The solution in that post is here - -
