I am using my company mailbox since 2011. It has 18gb and >120.000 emails. I feel it very slow since several weeks and would like to archive a bunch of mails. Whats the right approach for archiving in an Apple Mail + Exchange (Office365) environment?

  • I would prefer to keep the mails online, not on any of my machines
  • I would like to automate it
  • I expect to significantly increase search speed on normal searches...
  • ... but to be able to search through archived emails as well

Looking forward to your input. Thanks!

Sorry for not explaining much in detail considering that the questions are self-explanatory and the links I added had the rest of the solutions. As been already explained, the mails have heaped to a huge bulk, probably, thus filling up the inbox and slowing down your account. Archiving them all is definitely a good option. This article will explain you how to archive your mails for Apple mail: https://support.apple.com/en-in/guide/mail/use-the-archive-mailbox-mail35918/mac Avoiding machine storage leaves you to options like Dropbox and Google drive. I recommend Google drive for its unlimited storage capacity. You need to install google drive on your system. This thread speaks how to save your emails to google drive: https://productforums.google.com/forum/#!topic/gmail/gCc99XgqMzw;context-place=forum/gmail/categories This manual process carries the chances of losing out some of your mail contents. You can use Mail Backup X for the job. It sets the right sync between your mails and the storage location.
