I'm running Exchange 2013 on Win Server 2012 R2. My clients are using Outlook 2013. One particular user is the Sales assistant and she has access to one or two shared mailboxes. However, she also needs access to the email accounts of the two sales reps in order to monitor and reply to recent emails and manage their calendars.
Between her mailbox, the shared mailboxes, and the mailboxes of the two sales reps, the .ost file is around 10GB which is on the larger side of things. One of the reps mailboxes syncs without any issues while the other one (slightly larger) disconnects and needs to be updated manually. I've attempted synchronization filters
but that didn't seem to help reduce the size. Is there any way to go about keeping shared mailboxes synced while only syncing the most recent 1 or 2 weeks of mail? Or should I be disabling caching of shared mailboxes completey?
