<div>
I don't see anything with the actual error. However, I can tell you this is usually caused by the second user not being set up properly as a delegate for the calendar. Did they do it this way, or did someone try and use the admin console to change their security?

Hello,<br />
Does this error appear when the user attempts to open the calendar or is it when she attempts to add/modify an appointment?<br />
<br />
Does this issue persist? It appears to be a temporary error message related to your exchange server.<br />

Perhaps some permissions got changed by accident. Have the user revoke permissions and then make the other person a delegate again.

<div>
Hi kfalandays,<br />
<br />
the message appears when the users tries to add/modify an appointment.<br />
This message persists every time an entry is made in the users calendar <br />
<br />
Thank you
