I have over 60 users on our system but for some reason 2 users are not getting every email in their outlook 2010 client.  The emails come in fine to their Iphones and if you look in OWA they are there but they are not coming to outlook.  It's only a very small percentage that isn't making it but most of the time they are important emails and some have pdf attachments(contracts) and some don't ...... I was able to get them to come in by turning off exchange cached mode but some emails are still not syncing and things that have been deleted are still there.  I'm pretty confused here and would love and appreciate some help here.  Thanks ahead of time for any suggestions possible.

What's the size of the local Outlook profile? It will usually start acting funny above 5GB or so, but in general this depends on many factors and results will vary. Still, if the OST file is above 5GB, this will be my primary suspect.

Hello,

The most possible cause should be their Outlook profile and the most efficient solution for this kind of issue is to create a new Outlook profile and resync with Exchange Server.

Thanks,
