Feature Video | MDaemon Connector Overview


  • The MDaemon Connector Outlook plug-in requires Windows 7 or newer and Outlook 2013 or newer to function properly.
  • Users with large mailboxes may experience reduced performance using MDaemon Connector in comparison to using an IMAP or POP3 account. This is most noticeable when opening Outlook, when large folders are accessed for the first time, or when accessing the Journal folder.
  • Compatibility with third-party Outlook plug-ins and mobile device synchronization software cannot be guaranteed. MDaemon Connector does not make use of PST files. Compatibility with any software which requires PST files should be checked before the purchase. In some cases, adding an empty PST file to the MDaemon Connector profile may help.
  • S/MIME encoded (digitally signed) emails are not currently supported in MDaemon Connector.
  • Outlook's search folders will only reflect changes to items if Outlook has been re-started.
  • Outlook custom forms and custom template files (.OFT) are not currently supported by MDaemon Connector.
  • The Activities tab for Contacts may not work or may cause Outlook to hang (on very large profiles).
  • Roaming users should relocate their MDaemon Connector cache files (LocalCache.db) on a network share so that the data does not roam with their profile.
  • We recommend using the latest version of MDaemon Connector on both the MDaemon server and the latest MDaemon Connector plug-in on the client.
  • We recommend using MDaemon Connector with MDaemon 16 and above.
  • We recommend disabling all Outlook plug-ins except the MDaemon Connector plug-in
  • Regular defragmentation of the MDaemon server's hard disk is recommended. Server performance can be further improved by reducing the amount of logging MDaemon is doing (Setup | Server Settings | Logging | Settings) along with moving the Logs folder and User, Public, and Queues folders to a physically separate disk.
  • We recommend periodically purging and compacting the MDaemon Connector database file.
  • The local MDaemon Connector cache file should be excluded from real-time third-party scanning by third party desktop antivirus applications. By default, the local MDaemon Connector cache is located C:\Users\(username)\AppData\Roaming\Alt-N\Outlook Connector 2.0\Accounts\(Profile Name)\(email address)\LocalCache.db
  • Outlook should only be configured to use HTML or Plain Text format for sending emails. Depending on the version of Outlook you are using, these settings can usually be found via Tools | Options | Mail Format tab. Outlook should not be configured to use Word as its email editor or to use Rich Text Format (RTF). Both of these methods result in emails that do not adhere to Internet standards.
  • We recommend configuring MDaemon Connector's Send/Receive tab (located under the Account button in the MDaemon Connector toolbar) to only check the Inbox folder for new items at each Outlook send/receive interval.
  • We recommend configuring the Send/Receive schedule to check for new mail every 3 minutes.

Note: If you are planning to import data from a PST file, make sure to run scanpst.exe on the file first and compact the folders to help prevent corrupted messages from being imported into the MDaemon Connector profile. Scanpst is located under C:\Program Files\Common Files\System\MSMAPI\1033 and comes with Outlook. Note that multiple passes with Scanpst may be needed.

Note: Remove invalid characters ( ~ # % & * { } / \ : < > ? | " ) from Outlook folder names prior to importing.
