So will that hang outlook until the entirety of the pst file is uploaded? The client is on dsl so the upload may take a long time, even for a weekend.
Do you know of a program that will let you pick and choose a little more so I could batch it up or delelect some stuff?
How much it will "hang" depends on many factors.
*The health of the computer you're working on....
*Amount of cores of that computer, and if it's 32 or 64 bit Office, as well as how much memory of course..the more, the better...as Outlook can put more working data up in system memory to move it better instead of hitting the HDD like a mofo.
*Antivirus on that computer...and how intrusive, or not, it is in Outlook (you may want to disable its realtime and Outlook integration while uploading this) (Hosted Exchange has its own antivirus which is quite good, so I would not worry)
*The speed of the internet connection you're doing this on, specifically upload speed
*The power of the router you're working behind, current load on it from other stuff going on on that network, and its ability to handle many concurrent sessions (Outlook < = > Exchange can put a good load on it)
*Do the upload over a wired ethernet connection and not their wireless connection. You don't want something to fall sleep or drop the connection at all during the process, especially if it's an unattended upload. Make sure power saving stuff is turned off for this process.
Outlooks native import from PST feature allows you to cherry pick a bit...but honestly I don't like getting into customers e-mail like that...I don't know what they want to keep or not, and if you have gigs and gigs of e-mail to sift through...how can you expect to sort this out with them? It would take hours of discussion and looking. Just grab the whole dang thing and upload it.
When all done, make sure Outlook has closed the PST (personal folder)...so your client doesn't get confused as to which mailbox they should work in.
When done, move his original PST elsewhere out of the Outlook folder, I usually put it in something like C:\Download. Just to keep the Outlook directory in the users profile a bit cleaner. Maybe burn a copy to disk as a backup of current mails. "just in case".
