Hi,
We have migrated Exchange 2003 to Exchange 2010. Exchange 2003 is not decommissioned, but is turned off. After migrating users have issues, that outlook 2010 inbox not auto updating. Sended mails users receive in 5-30 min interval. Pressing F9 not helping. Only Shift+F9 retrieve new mails.
Any ideas on how to resolve this problem?
P.S. sorry for my english
