Moving IMAP Mail items within Outlook Causes Incorrect Timestamp in IOS Native Email Client

Problem: Using Outlook to move an existing mail item from an Outlook PST or IMAP folder into a different Outlook IMAP folder causes the IOS native email client (INEC) to display the ‘wrong’ date/time – that of ‘now’, rather than the time when the item was received or sent.

Whether or not relevant, such a move also changes the item’s ‘modified date’ as displayed in Outlook as follows: a) A move whilst Outlook online changes that date b) A move whilst Outlook offline does NOT change that date upon the move, but does change it to the time at which you subsequently go back online. (and that time is also what is seen in IOS)

Possibly the iCloud server is imposing today’s date/time as described by Nicolson (Search Nicolson “RFC 3501 section 6.3.11” re: Gmail.)

However, some items in IOS display a different date from what Outlook shows as ‘Modified’, it seems likely that IOS is not using whatever variable Outlook uses for ‘Modified Date’.

Moving an item between folders in the same Outlook PST does NOT change the item’s ‘modified date’ as seen in Outlook.

Moving in INEC or iCloud Web: Moving a message between folders within Icloud Web or INEC does NOT 13change the modified date/time shown in Outlook IMAP folder, or the date/time shown in Icloud Web or INEC.

Gmail Behavior: By comparison, using Outlook to move mail items into Gmail IMAP folders also causes the Outlook ‘modified’ time to change. But the INEC client (and the Gmail app) show the ‘correct’ timestamp – the date the mail was received/sent.

Outlook 365 64bit latest release running on Windows 10 64bit. IOS 13 running on iPhone 6s.

Tested on two different PCs and two different iCloud accounts. Based in UK time zone.

Even if no one has a solution to this it would be helpful to know if anyone can replicate the problem.

P.S. When using Thunderbird to move a mail item between two iCloud IMAP folders the date as shown in INEC and iCloud mail is NOT changed – the ‘correct’ timestamp is seen.

Unfortunately the outcome is as described whether I setup the iCloud mail account using iCloud for Windows, or whether I do it without.
