There is Exchange 2010SP3 at Win2008R2 + Outlook2010SP2 at Win7SP1 + ExtraOutlook1.3 for run Outlook multiple instances with different profiles. One profile - one Exchange account. All work fine, multiple different profiles is opend well, each Outlook instance shows correctly mail, GAL, ALs (address lists) , mail is sent and received correctly. But hovering pop-up contact card (small whiet windows is appeared while hovering mouse cursor or double clicking to sender / receiver in new message or sent / received one with contacts data) is shown full info only for last started Outlook instance. For Outlook instance before last, contact card shows only display name and not always but offen e-mail address and name resolving works fine, GAL is displayed correctly. And if to switch to legacy GAL showing contact data (using TurnOnLegacyGALDialog) all works fine also. I have not yet investigted where reason is, at server or client side. Where is reason ofnsuch behaviour ?
