One of my customers is having problems with Exchange not syncing correctly with outlook clients.
Two people are known to be affected. The worst affected person is running Outlook 2013, the other is on Outlook 2010. I was finding that quite often her sent items were not appearing in the exchange client.
The user has full access and send as access to multiple accounts granted through the exchange management console. Quite often updates to these other accounts are not visible in her outlook.
The offline cache file is getting quite big, around 20GB, I imagine because it is caching all of the accounts she has access to.
I've been running her without cached exchanged mode for several months, and this works much better, however this is stopping her from being able to search her email correctly.
I've tried deleting the .ost file and allowing it to be recreated, I've also created a new profile on her outlook.
No real improvement.
