Hi Peter, I've changed the Subject on my reply email to a more relevant name, to make searching the WAMUG Archives easier.
I don't need to remind people to have a current "Backup". On 10 Sep 2014, at 6:57 am, petercr...@westnet.com.au wrote: > Thanks for this Ronni.

Yes, Archiving old Messages from Mail, especially if your mailboxes become really large you'll often experience slow Mail performance on your Mac. You can archive these messages without losing them. What you need to know: * Once you archive your emails they won't be available on any of your Macs or devices -- they will only "live" inside your archive mailbox. * This also makes it essential you backup your Mac, so you won't lose these messages if disaster strikes. * Archiving only works if you have Mail set up to remove deleted mail from the server sending mail to that account. (Mail>Preferences>Accounts>Mailbox Behaviours>Trash. Uncheck - "Store deleted messages on server"). Step one: Launch Mail and choose Mailbox > New Mailbox. Now name the mailbox (Archive 2010-11, for example) and choose On My Mac as the location. Press OK and the mailbox appears in the list at the left. Step two: Select the messages you wish to archive. You might want to choose all the mail you received between 2010-2011, if that happens to be appropriate to you. Once you've selected the messages you wish to archive, 'drag & drop' them into your new Archive mailbox. Repeat this until all your messages are in the new Archive 2010-11 Mailbox Step three: With all your messages in the Archive, it's time to export them. Control-click on the mailbox name in the list on the left, and select Export Mailbox... from the contextual menu that appears. You can also do this by choosing the mailbox and using Export Mailbox in the menu. Step four: Choose where to save your archive, but remember to check Export all subfolders, if you have any, to export. Click Choose. Step five: Exporting your mail will take time -- it could take a long time! Step six: Once export is complete, you'll see an mbox file icon appear where you exported the Mailbox too. Do check to make sure all the mbox files and subfolders you created are there. Step seven: Now delete the Archive you created in Mail by Control-clicking the mailbox and selecting Delete Mailbox. Don't worry -- all your messages are already saved in your exported Archive. Step eight: Whenever you need to search messages stored inside that archive, you should launch Mail and select File>Import Mailboxes, (select Apple Mail as data format). Click Continue and navigate to the exported archive(s) on your Mac, select the right collection and click Choose. In a little while, all your archived mails will reappear in Mail. Find the ones you need and copy, print or move them. Now, you can delete the Archived Mail you just imported (Right-click, Delete Mailbox) -- all your archived mail remains safe in the originally exported box. Conclusion: This is how to cut clutter from Mail without losing any important messages. There are third-party Mail archiving solutions that might be more straightforward to use. A long time ago I used 'Email Archiver Pro.app' but from what I remember I didn't find it more convenient. My Mail is HUGE... With SIX enabled email accounts! The amount of email I receive and send daily is quite unbelievable :( Cheers, Ronni 13-inch MacBook Air (April 2014) 1.7GHz Dual-Core Intel Core i7, Turbo Boost to 3.3GHz 8GB 1600MHz LPDDR3 SDRAM 512GB PCIe-based Flash Storage
