Notes:
* ZCO connectors are backwards compatible. If running a newer ZCO version, you must uninstall it before installing an older version.
* There may be incompatibilities with older versions of ZCO and newer versions of Outlook.
* The major build number in the ZCO file name has no bearing on the version. 8.8.15.1902 and 9.0.0.1902 are the same. The build ID is the last portion of the version. In the table below, it is the first column.
* Zimbra always recommends using the latest version of the connector when possible. Downgrade at your own risk.
* In cases where ZCO versions spanned multiple patches, the date listed is the date in which the ZCO version was introduced (the earliest patch).

|Fixed an internationalization problem with the mailbox rules "Run Now" feature, that caused an error message if the language was set using a Language Interface pack instead of the language options in the advanced settings.<br>Signatures containing external images (URL references) had those images added as attachments to messages. Such messages would appear in "has:attachment" searches when the only attachment was the signature image.<br>Users now have an advanced option, "Signature pictures sent as attachments" to control this behavior. When disabled, the image URL will be used without an additional attachment, thereby reducing the size of the message.<br>
