LDAP: managing exchange features using protocolsettings attribute
12-03-2008Active Directory stores the contents of the “Exchange features” tab in various attributes. The protocol settings for Outlook Web Access, POP3 and IMAP4 are stored in the attribute “protocolSettings” (multi-valued). If you leave everything to default, this attribute is not populated for new user accounts. If you change a setting this attribute will get a value. The possible values are:
- HTTP§0§1§§§§§§
- POP3§0§1§4§ISO-8859-1§0§§§
- IMAP4§0§1§4§ISO-8859-1§0§1§0§0
The first number value after the § determines if the protocol is enabled. In the above listing, all protocols are listed with number 0 as first value, so they all are disabled. To enable, replace the 0 with a 1, leaving the rest of the string untouched. The other values on the “Exchange features” can be modified as well using the msExchOmaAdminWirelessEnable attribute. The value for this attribute changes all 3 settings:
- 0: All enabled
- 1: OMA = Yes, UIS = Yes, UtdN = No
- 2: OMA = No, UIS = Yes, UtdN = Yes
- 3: OMA = No, UIS = Yes, UtdN = No
- 4: OMA = Yes, UIS = No, UtdN = Yes
- 5: OMA = Yes, UIS = No, UtdN = No
- 6: OMA = No, UIS = No, UtdN = Yes
- 7: All disabled
On Exchange 2007, use the PowerShell cmd-let “Set-CASMailbox”, for instance:
- Set-CASMailbox “CN=user,OU=accounts,DC=tools4ever,DC=local” PopEnabled $true
- Set-CASMailbox “CN=user,OU=accounts,DC=tools4ever,DC=local” ImapEnabled $false
