If you receive the error message “Unable to complete command” when trying to send email using Nokia Mail-for-Exchange then you may be interested in the solution that worked for one of my clients.
In my case the problem was caused by one of the client’s default Exchange folders not being present in the Exchange mailbox root directory.
The default folders are:
- Inbox
- Drafts
- Sent items
- Outbox; and
- Deleted items.
You can check if these folders are in the root directory by looking at Outlook Web Access and ensuring that the default folders are present.
Please be aware that, in addition to having the appropriate name, the default folders should have an icon superimposed on the usual folder symbol.
The reason that I suggest checking this in Outlook Web Access is that I discovered that the Outlook Desktop Client does not always show the default folder icons. It is therefore difficult to identify what is a default folder and what isn’t.
For example, my client had a folder labelled “Drafts” in the root directory, but it did not have the Draft folder icon. The default Drafts folder had somehow become a sub-folder of an Inbox folder.
The folder labelled Drafts in the root directory was therefore not the correct folder.
Once you have established that one of the default folders is missing from the root directory then you must move it into the root directory.
A further complication in my case was that I couldn’t move the default Drafts folder using Outlook Web Access, I could only move the default Drafts folder using the Outlook Desktop Client.
Once you are certain that all the default folders listed above are present in the root directory then you must delete the Mail for Exchange account on the Nokia phone and then repeat the account configuration process.
This enables the Mail for Exchange account to recognise the default Exchange folders.
Once this has been completed your phone should now be able to send email without the “Unable to complete command” error message appearing.
NB The procedure described above worked for me with a Nokia C5. There may be other reasons for receiving this error with the Nokia C5 and other Nokia phones that use Mail-for-Exchange.
