I just upgraded one of my users from Outlook XP/2000(Not sure which one, although pretty sure it was xp), to Outlook 2003.
When he hits send/recieve he gets the error message...
"The message store has reached its maximum size..." and tells him to delete mail.
We have the new Exchange SP2 R2 and your mailbox storage has been set to 70 gig, and the users themselves dont have any mailbox size limit, I checked both the storage group and the public group.
His mailbox size right now is approximately 1.6gig and I believe they used to be bigger.
He appears to be receiving mail but it always comes up with the error message.
I turned cached exchange mode off and didnt seem to fix it.
