For two of our users, the Outlook (2010 SP2 32-bit) inbox on their computers has stopped updating. They can send an email and the recipiant gets it. They can use OWA to see their new emails. The OWA inbox seems to work.
I have tried repairing the account through account settings. I also tired reparing Office in 'Programs and Features'. I have tried 'outlook /safe' as well.
We use Windows 7 SP1 32-bit and Exchange Server 2010
Is there a common cause for this? Is there something I should look at first? What else do I need to try?
