Mail limitations

The following table describes mail limitations.

Table 1. Mail limitations
Description More information
When you delegate mail file access to someone, that person must use a client other than Outlook to manage the mail file.
Initial sync can be lengthy and can display older items before more recent calendar and email entries. Local mail storage is required; some delay in mail download during start-up is possible.

In general, IBM® attempts to sync the most recent data first, and then filter in older data, though the process continues to be refined. There are cases, however, where the initial download is not ordered as expected, particularly with very large mail files.

By default, existing mail that is more than 30 days old is not synced to Outlook when you install and set up the IBM® mail client.

An administrator can control the number of days worth of existing email that is initially synced.

If you already use Outlook, you can back up older existing mail in a local archive file to make it available in Outlook after you install the IBM mail client. For more information, see Archiving existing mail in advance (current Outlook users).

Messages that are more than 30 days old at the time they are downloaded are truncated (the administrator can modify or remove this setting). Double-click a message in a folder or mailbox to download the full content.
Attachments in outbound messages are limited to 15 MB. You cannot send messages that contain attachments that exceed this limit. To workaround the limitation, store files that are larger than 15 MB in a repository such as Box or Connections and link to them in messages.
The Clean Up Conversation option is not supported.
When new mail arrives, a pop-up notification isn't shown. To work around this issue, create a rule:
  1. From the Home tab, click Rules.
  2. Select Manage Rules & Alerts.
  3. Click New Rule.
  4. Select Apply rule on messages I receive.
  5. Click Next.
  6. Click Next.
  7. When you see the message This rule will be applied to every message you receive. Is this correct? click Yes.
  8. Select Display a Desktop Alert.
  9. If you see the message The rule you are creating can never be edited in previous versions of Outlook... click Yes.
  10. Click Finish.
  11. Click Apply.
  12. Click OK.
If you have used the Send and File option in the Notes® client, messages will only appear in the Sent items folder in Outlook, and will not appear in the folders you filed to. Outlook cannot have a document in more than one folder.
Use of Microsoft Outlook Rich Text formatting is not supported (use the default of HTML)
Mail tips do not work with Microsoft Outlook.
Message recall is not supported
Requesting and receiving delivery receipts when sending mail messages is not supported; the Outlook option "Ask each time whether to send a read receipt" is not honored
Assigning a Category to an email message in Outlook does not sync to the server, and remains local to the Outlook client.
Forwarding and Receiving Outlook objects works by converting the forwarded items to attachments (*.EML attachments when viewed in Notes®, and *.MHT attachments when viewed in Outlook). There are two caveats:
  • Non-inline attachments in a forwarded message will not be accessible for Outlook recipients. As a workaround, simply forward the message; do not forward as an attachment.
  • Forwarding as an Outlook Contact does not work. As a workaround, forward a contact as a .VCF file, and the recipient will be able to import it.
Microsoft Outlook add-ins are not supported (Requires additional Microsoft Exchange server configuration)
Email signatures will not be synched from Microsoft Outlook to the server
Encrypted messages cannot be read in the preview pane, messages must be opened to read them
If you have IBM® Notes® mail rules defined, and create mail rules in Microsoft Outlook, the Notes® mail rules will be applied prior to execution of the Outlook mail rules. The reason for this is that the Notes® rules run at the server, whereas the Outlook rules are not applied until the mail syncs to the client. Be aware of the differences in mail rules and adjust either IBM® Notes® or Microsoft Outlook rules accordingly. Also note that creation and modification of server-side mail rules is not supported.
Follow-up flag reminders do not sync between Outlook and other mail clients such as iNotes. Note that the flags, follow up dates, and follow up text do sync.

By default, the ability to archive mail to a store such as a .PST file is disabled for the IMSMO profile and all other third-party profiles. This default behavior prevents you from inadvertently losing data during the archive process. It also protects you from moving your data to third-party sync applications such as iCloud for Windows that may not be responsible with your corporate data.
