The list represents issues which should be considered prior to deployment. It should not be taken as definitive or complete, and we always recommend testing the products in your own environment to ensure that compatibility and features work as required prior to purchase. - MDaemon Connector requires Windows 7 or newer and Outlook 2010 or newer to function correctly. - 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, when searching folders, or when accessing the Journal folder. - Compatibility with third party Outlook plug-ins cannot be guaranteed. MDaemon Connector does not make use of PST files. Compatibility with any software which requires PST files should be checked prior to purchase. In some cases, adding an empty PST file to the MDaemon Connector profile may help. - In Outlook 2010 and above, custom category names/colors may not be retained after Outlook is restarted. - The "Show as Conversations" option is not 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.   **General Use Recommendations** - We recommend using the latest version of MDaemon and the latest MDaemon Connector plug-in for Outlook. - Check the **[Support](https://www.altn.com/Support/)** page to verify which is the earliest version of MDaemon and the MDaemon Connector for Outlook. - The latest Service Pack needs to be installed for all versions of Microsoft Outlook for MDaemon Connector to run correctly. - 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 scanning by desktop antivirus applications. By default, the local MDaemon Connector cache is located in the following location: - **%APPDATA%\\Alt-N\\Outlook Connector 2.0\\Accounts\\%OUTLOOKPROFILE%\\%OUTLOOKEMAIL%\\** - Outlook should 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 which 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.exe should be located under one of the following folders. Outlook 2019 64-bit C:\\Program Files (x86)\\Microsoft Office\\root\\Office19 Outlook 2016 32-bit C:\\Program Files\\Microsoft Office\\root\\Office16 Outlook 2013 32-bit C:\\Program Files\\Microsoft Office\\root\\Office15 Outlook 2010 32-bit C:\\Program Files\\Microsoft Office\\root\\Office14 Other possible locations: C:\\Users\\%username%\\AppData\\Local\\Microsoft\\Outlook\\ C:\\Users\\%username%\\Documents\\Outlook Files\\ **\*\*Note** - Multiple passes with ScanPST.exe may be needed. **\*\*Note** - Remove invalid characters ( ~ # % & \* { } / \\ : < > ? | " ) from Outlook folder names prior to importing. **Additional Notes** - The latest Service Pack needs to be installed for all versions of Microsoft Outlook for MDaemon Connector for Outlook to run. - Current known issues with using MDaemon Connector for Outlook with Microsoft Outlook 2010/2013/2016/2019/365: - "Show as Conversations" does not work. - "You must restart Outlook" prompt is displayed when creating an MDaemon Connector for Outlook profile - [MDaemon Email Server](https://knowledge.mdaemon.com/mdaemon-email-server?hsLang=en#main-content) - [Mobile Device Management](https://knowledge.mdaemon.com/mdaemon-email-server?hsLang=en#mobile-device-management) - [MDaemon AntiVirus (SecurityPlus)](https://knowledge.mdaemon.com/mdaemon-antivirus-securityplus?hsLang=en) - [ActiveSync for MDaemon](https://knowledge.mdaemon.com/activesync-for-mdaemon?hsLang=en) - [MDaemon Connector for Outlook (Outlook Connector)](https://knowledge.mdaemon.com/mdaemon-connector-for-outlook-outlook-connector?hsLang=en) - [SecurityGateway for Email Servers](https://knowledge.mdaemon.com/securitygateway-for-email-servers?hsLang=en) - [RelayFax Network Software](https://knowledge.mdaemon.com/relayfax-network-software?hsLang=en) [![Chill listening crop-3](https://knowledge.mdaemon.com/hs-fs/hubfs/belch.io/template-assets/MDaemon-Technologies_logo.png?width=199&height=41&name=MDaemon-Technologies_logo.png "Chill listening crop-3")](https://www.mdaemon.com) [Knowledge Base Home](https://knowledge.mdaemon.com?hsLang=en) Copyright © 2025, MDaemon Technologies
