I am in the process of migrating clients from Exchange 2003 to my Smartermail 12.x box. Client made decision to cut over clean fortunately. Using Outlook 2010 we are exporting everything off the old system to local archive PST and starting fresh with IMAP account connection to Smartermail. I am using "Add to Outlook" for Contacts and Calendar sync. Users connect to smartermail with phones & tablets using ActiveSync.
I am having a problem migrating Contacts using Outlook 2010. I put the old contacts in List view and select all. Then right-click "Move | Copy to Other Folder" and copy contacts to the smartermail SharePoint List Contacts folder, I get a warning that incompatible items will be put in deleted items folder, then all contacts seem to move over just fine. However on the next send/receive upwards of 80% of the contacts disappear from the SharePoint List Contacts folder.
Any suggestions? Do I need to do a manual CSV export or something then import into Smartermail web interface? No option to use mailbox migration feature for contacts as the original server is Ex 2003.
Thanks in advance for any and all ideas/responses.
