Note: Outlook will sync emails in the OST file till the period for Offline mode is chosen. If you choose to keep offline for 6 months, then only emails from the past 6 months will be synchronized into the OST file, rest emails will remain in the primary mailbox.

Note: Exchange and Office 365 accounts can synchronize emails from the past 12 months only.

Another important factor to set the offline period intelligently is the time required for Outlook to open the account. Also, it can change the storage space necessary for synchronized OST files. If you are working in a virtual environment, then you should keep synchronization for one month only.

It is Disconnected mode and the mailbox loses a connection with the email server permanently. Additionally, the emails are not synced in the OST file in the disconnected mode.

There can be following reasons behind such problem:

  1. If Outlook has an internet connection, but there are technical issues on the email server side.
  2. If your account is operational in Outlook on the Web, then there are problems in the desktop application.
  3. If the account is not working in Outlook on the web, then you should contact your account administrator.
  4. If you are getting emails in the inbox, then the account is fine.

You can reconnect your account with outlook using the following techniques-

  1. Use the similar Work Offline option under Send/Receive tab and see if the status is changing. It will try to connect with the mail server.
  2. Check for possible updates in either the mail server or Outlook.
  3. For Office 365 accounts, you can log out and log in again.
  4. If there are chances for deletion in your account, then you should recreate the profile once again. Delete the existing account and recreate it again.

If some updates are underway in the Exchange Server, then you can choose Offline mode but later back to switch from working offline to online in Outlook after updating. You will not receive new emails, but the account will remain active to process the remaining tasks. You can access emails, contacts, calendar entries, notes, tasks, etc.

Due to any fault line in the bad status changing, your whole mailbox can become corrupt and you cannot use the Work Offline button because it will become inactive.

The software will perform a deep scan and recover all items that you can preview.
