Outlook to iOS Sync
This guide describes how you can sync between Outlook and iOS devices using an ownCloud server appliance and OutlookDAV 6.3. Besides ownCloud, any other WebDAV server could be used.
Tools
| Tool | Version | Appliance | Sync | Cost | Support | Maker |
|---|---|---|---|---|---|---|
| OutlookDAV | 6.3 | Windows Service | fast 1) | 15 USD p.a. | developer, fast | Comodo |
| WebDAV Collaborator for Outlook | 1.6 | Outlook Plugin | fast 2) | 29 USD o.t. | no support 3) | Bynari |
| cFos Outlook DAV | 1.6 | Outlook Plugin | fast 4) | 29 USD o.t. | no support 5) | cFos |
I tested many different sync solutions. OutlookDAV and WebDAV Collaborator were the only tools which actually worked. OutlookDAV runs as a windows service, which has the huge advantage in that it does not slow down Outlook or make iresponsive during syncing.
By far the best is the WebDAV Collaborator for Outlook, which is free for a one month trial period, after which it costs 29 USD. I also tried cFos Outlook DAV, which synced the calendar data ok, but I could not figure out how to properly control the sync process so it would not freeze my Outlook during syncing.
Both are Outlook Add-ins, run the installer and they get added to Outlook. The configuration is similar, below's guide applies to WebDAV Collaborator for Outlook.
Before you sync, consider to delete unused address entries, and Delete or archive older calendar items.
