We have a weird issue going on.
A month ago, we enabled Conflict Percentage Allowed (30%) andMaximum Conflict Instances (365) on the Resource Policy tab on our Room Mailboxes across the entire company.
Ever since then (it appears), our delegate users have the "spinning blue circle" when they click on any accepted or declined responses (on behalf of one of the users they are a delegate for).This does not happen if the delegate books a meeting on their own. This is a considerable length of time (upwards to a minute) and Outlook will show asNot Responding.
Exchange 2010 SP3 (happened under SP2 RU4 as well)
Outlook 2010 ver. 14.0.6106.5005 32 Bit
