I just want to save you some headaches a year or two down the line. It took me a while to narrow down what was wrong with some of my users Outlook, after talking to another Sysadmin who experienced the same problems I found out it was over-sized PST's. The problems are a mixture too, sometimes outlook will fail to start, sometime it’ll stop sending and receiving, sometimes it will randomly delete mail, other times the entire file can get corrupted. PST( ), I HIGHLY recommend you keep them no higher than 1.5 Gigs anything over that will cause problems. OST file (very Frustrating).Ī side note: Although Outlook 2003/2007 allows up to 20GB. I recently consolidated users in my company onto one domain and had to deal with the re-download of the local. However I have never tried this and cannot condone it. OST file, stop the download, and replace the new. A quick search of Google shows there are ways to create the. When you configure Outlook's connection to your Exchange server it has to create a new local. As far as re-downloading the mailbox when a user gets a new PC: this is also something that will have to happen with cached Exchange mode. Outlook/Exchange is not smart enough to limit the traffic, you will need to configure QOS if you plan to do this during business hours. To start: yes it is going to completely kill your inter-site performance. Looking further down the road, what happens when a user with a 5 GB mailbox moves to a new computer? Does the entire 5 GB need to be re-downloaded, or can the OST from the previous computer be used to accelerate the process? If all the users start copying their messages into their Exchange mailboxes at once, will this kill our inter-site performance? Is Outlook/Exchange smart enough to reduce bandwidth use when the network connection is saturated, or do I need to ensure that QoS is configured before starting this?

We have three sites with the following bandwidth specs: We have a 30-40 GB of stored messages for all users combined, with some users having PST files that are several GB in size. I'm concerned about the bandwidth implications of having users upload all of their archived messages.
The only data still in PST files is archived email. So far we have been able to easily migrate calendars and contacts from old PST files into Exchange without any problems. We recently started using Microsoft's Hosted Exchange offering with Outlook 2010, and are very happy with it.
