![]() ![]() ![]() Without that, imapsync wouldn’t pull the emails from Emailchemy. The important bits are really “disarmreadreceipts” (Exchange issue) and “noabletosearch”. imapsync -no-modules_version -errorsmax 1000 -noreleasecheck -noabletosearch -maxsize 26214400 -disarmreadreceipts -nolog -host1 localhost -port1 8143 -user1 "import" -password1 'mymail' -sep1 "|" -host2 -ssl2 -user2 "username" -password2 'password' Because of few of the messages on this user’s POP account were poorly formatted, I had to up the errormax in imapsync to 1000 or so. Now, using imapsync, you basically just need to point it at the local Emailchemy IMAP server, and your exchange server (make sure IMAP access to Exchange is enabled). Once that conversion is done, you can then go to “Tools” in Emailchemy, and “IMAP Import Server”, point it at your exported file/directory, and “Start”. Emailchemy has a nice builtin IMAP server for just these kind of occasions. Now, at least, they’ll start getting new email.įrom Emailchemy, using the Basic Conversion, point it at their Mail folder on the desktop, and save it as an imapserver file. Once that’s done, go into Internet Accounts and delete their pop3 account, and add their Exchange account. I used a 2nd machine to do the conversion so they could use their machine without problem (and I could easily have a working copy of imapsync, but YMMV). Quit Mail on the users computer, and then go to ~/Library and copy their “Mail” folder to their desktop. Based on how we do migrations, this will be the quickest way to get them receiving new email while the rest of the stuff runs in the background. The only other tool I used was imapsync to migrate the email. ![]() I purchased an application called Emailchemy to do the worst part. So all the mail I manually copied over had the wrong “Date Received” (it moved to the day I did the migration, not the date it was actually received). It doesn’t use the header in the message (that header is instead reflected in “Date Sent”). Except then, a problem arose.Īpple Mail (Mail.app) uses the filesystem date/time as the “Date Received” in views. After beating my head against a wall trying to automate this migration, I finally just did it manually for one user. Sadly, of those 60 or so, 3 of them were using POP3 and Mail.app. Since I had been doing this on my own for a while, when the call went out officially, I only had about 60 users to do. In an effort to “simplify” things, IT units around campus are being tasked with migrating all employees over to Exchange. One linux based, using Dovecot and Sendmail, and the other being Exchange 2013. My work, or University as a whole, has two email systems. ![]()
