That one will show you exactly what is going on and who or what is slow. To monitor what is slowing your Apple Mail down open the Activity under Window Tab in Mail. It looks like this on my mac for one of the accounts: If you right click on you gmail account in Apple mail and ask for Account information you will get the limit information you have with the gmail on they server. You can have more space with gmail account by converting it to premium (pay for it).įolder limit is none (as many as you like) In my case I have 2 gmail accounts each with 16 Gig Quota Limits- those are standard gmail accounts. The limit is only what your gmail (Google) account gives you. If you're reaching a Mail-Count of more than 200k, you are probably collecting a decade of mails (unless you are writing a lot).Īfter 3-5 Years you should store those mails on a Backup Server (Maybe at a different location), safe for nobody to access and safe regarding any kind of loss. Also roundcube as a Frontend is much faster when going through severel houndred of thousands of mails.

The Server can handle those Mails a lot better than Apple Mail. In our company we have a Linux Mail-Server and a Roundcube Frontend with a MySQL DB. I use a OS X (Mail-) Server with a Roundcube Frontend and a MySQL Database. Having your own Server for that helps a lot. Don't go beyond 10k Mails (in your main Postbox).It is not recommended having such a big MailBox at all. In effect, your Hard-Drive storage and the Performance of your Mac are the only limiting factors, not some count of messages in terms of size or number.Īs you already noticed, the app gets really slow with Mails over 100k or even 200k on current hardware (perhaps except the Mac Pro). Otherwise, you won't be able to restore deleted messages.The Limit is not something programmed into Mail. Note: After configuring Apple Mail, be sure to change the Trash setting to never permanently erase messages. Now the Mail will start to download your emails.Select the apps you want to use with this account and then click Done.If your account is enabled with Multi-Factor Authentication - MFA, you need to 'Approve' the login from the Microsoft Authenticator app.Email Address: Choose Sign In when prompt for the setup method.Full Name: the name you want displayed on your outgoing mail.Enter the following information and then click the Sign In button.Otherwise, go to the Mail menu and click Add Account -> Exchange and then click Continue.If you have not previously configured an account in Mail you will be prompted to add an account.(Click the icon in the dock or go to the Applications folder to open it.) Procedures: (Screen capture base on macOS 10.14.x with Mail app version 12.4) You can configure the Apple Mail app to connect to your email and calendar events on the Office 365 server.
