What to archive

By default the deleted items, the junk and the outbox are not archived, so if you need them, first click on the (…) at the Folders section of the screen, and in the next dialog box, remove the tick from the checkbox “Always exclude Deleted Items, Drafts, Junk Email and Outbox”.

Delete old emails that are already archived

You have the possibility to delete old emails from the users’ mailboxes. E.g. to save mailbox space, you may delete emails that are older than 2 years, because they are already safely preserved in the Mailstore Archive.

For this, click on the (…) in the Delete section, and in the next dialog box, choose “if message older than [] years” specifying your preferred amount of time.

Choose which mailboxes to archive

On the next screen, to archive all users, leave the “All users with configured e-mail addresses” option – Mailstore will archive the emails of all users that has been configured as a Mailstore user. If you’d like to exclude some users, you have two possibilities:

If you have a lot of users in your company, and you want to exclude only a few of them, the easiest way to do this is to choose “All users, except the following”. After that, choose the users that you DON’T want to archive from the list of users.

If you want to archive only a few users of your company, choose the “Only the following users” option, and choose the users that you WANT TO archive from the list of users.

Tick the checkbox in front of the option “Synchronize with Directory Services before archiving” to sync your user data from O365 before running the archiving profile.

You are not done yet! This will run the profile only ONCE. To make it run automatically on a schedule, set up an archiving job (next section).

Automatic archiving jobs

To automate the archiving process, please go to Administrative Tools > Management API > Jobs > Profiles > Archive E-mail

image-1610718547225.png

In the dialog box, give the Job a name, and choose the Profile that you previously created. Give a schedule. Please, use direct archiving only once, at most twice a day.

This archiving method is to preserve the folder structure of users. To meet legal requirements of storing ALL emails sent or received by specific mailboxes, you need to use Journaling.
