This protocol has a high level of optimization for quick synchronization, even in low bandwidth and high latency networks.

Enable/Disable Exchange ActiveSync with Exchange Management Shell

Using the Exchange Management Shell command also, it is possible to enable or disable the Exchange ActiveSync feature for Exchange user mailboxes.

Run the Exchange Management Shell application on your system as an administrator.

Execute the following command to enable Exchange ActiveSync for a particular Exchange user mailbox.

Set-CasMailbox -Identity “mailbox name” -ActiveSyncEnabled $true

Provide the user mailbox name at the bold place in the above command and enable the Exchange ActiveSync feature.

Now, to disable the Exchange ActiveSync feature for a particular user mailbox, follow this command.

Set-CasMailbox -Identity “mailbox name” -ActiveSyncEnabled $false

For enabling Exchange ActiveSync for all mailboxes within a particular department in a state or province, use this command.

Get-User -Filter “RecipientType -eq ‘UserMailbox’ -and Department -like ‘department name*’ -and StateOrProvince -eq ‘state or province name'” | Set-CasMailbox -ActiveSyncEnabled $false

To disable the Exchange ActiveSync for all mailboxes for the same department, just use the true parameter in place of false.

Get-User -Filter “RecipientType -eq ‘UserMailbox’ -and Department -like ‘department name*’ -and StateOrProvince -eq ‘state or province name'” | Set-CasMailbox -ActiveSyncEnabled $true

Exchange administrators can also use a .txt file with mailbox information (including email address and name in a row) to enable or disable the ActiveSync feature for the included mailboxes. Here is the command.

Get-Content “Txt file path location” | foreach {Set-CasMailbox $_ -ActiveSyncEnabled $false}

Check for all the user mailboxes for which the Exchange ActiveSync is enabled or disabled with these commands,
For Exchange ActiveSync disabled mailboxes:

Get-CasMailbox -ResultSize unlimited -Filter “ActiveSyncEnabled -eq `$false”

For Exchange ActiveSync enabled mailboxes:

Get-CasMailbox -ResultSize unlimited -Filter “ActiveSyncEnabled -eq `$true”

Therefore we have discussed all the possible native ways to enable or disable the Exchange ActiveSync for Exchange user mailboxes.

Final Words

Exchange Server mailbox information is stored in its database file known as EDB file, and its security is crucial. Due to unfortunate reasons like Exchange Server crashes, malicious software, bad registry entries, sudden system shutdown, etc., the file becomes corrupted, and thus Exchange information becomes inaccessible. For such situations, we bring you the advanced Exchange Server recovery tool, which delivers quick recovery of Exchange mailbox data after repairing even severely corrupted EDB files easily. The tool integrates a simple user interface and minimum steps for easy recovery of mailboxes. It allows users to save retrieved content to multiple formats and destinations. It also allows to export offline EDB file to Office 365. Detailed information about the tool is available on the website
