Hello all, I think that I may have made a mistake... A VP in our company was having some very strange errors with his calendar in his mailbox. To make a long story short, I had to recreate his mailbox. I recreated his mailbox almost 1 month ago after copying everything (Calendar, Inbox, Contacts etc.) to a PST file using EXCHNG32. I then deleted his mailbox from exchange, forced replication throughout the sites, re-created the mailbox, imported the PST files into his new mailbox and then forced replication throughout the site once again. This fixed his calendar issues. HOWEVER, now when people send him e-mails by pulling his name up in the GAL they get bouncebacks or when they try to change calendar items that were created before the new mailbox they get errors. The bouncebacks indicate mail is trying to be sent to his old X400 path. (ex. To fix this, I have to go to each persons PC that is having the problems and point to the GAL and select his name) For some reason, exchange seems to have 'memorized' his old address instead of pointing to the new one. The SMTP address is the same as his old one... Is there anyway to correct this without having to correct it on an individual basis? Chris
