Moving cached IMAP folders into OnMyMac when offline

If you try and move messages or folders in the IMAp folders of an account that is not online - you will be thwarted!

BUT if you take a copy of the files as shown here, and then re import them into your mail account, you can then safely point to another imap server and not lose all your cached content that would otherwise disappear!

Step 1 Create a copy of the folder that matches the list of mailboxes you need..
~/Library/Mail/Vx/RANDOM-NUMBER
I copied while Mail was open with no issue!




Step 2
From File choose Import and choose Apple Mail format.



The Imports create an Import folder each time you attempt it in the On my mac section.

Step 3
Then simply drag and drop the content of each folder, (or entire folders) up into either the On my Mac section,
Step3a or MOVE the folders into the IMAP folders area to upload to the new server... although I couldn't get this actually to copy so left this step out!
It may be that you need to create the empty folders on the IMAP are and then drag the mail items into each one ?

Autocomplete and Recently Used Contacts in Office 2016 2019

Occasionally a new cache file is built for some reason and the old one abandoned by Outlook.

Simply rename the current one in use (you can tell by the date), and then copy over the slightly older one (but it will have a large file size compared to the new one in use).

Restart Outlook – and Voila – it starts working again.

Now if we could only get the users to add these emails into their address book – or get Outlook to do that automatically!

 Kudos to this article for hints on the autocomplete file and overwriting it https://kb.intermedia.net/Article/1894

When its working - the user is greeted by these happy (full) dialog boxes :)

When I stops working (possibly due to the G Sync tool?) the user has no entries in these dropdown boxes and feels LOST!

To fix it, I simply copy over an older (but larger Stream_Autocomplete_xxx.dat file. In this case I could have used the one ending in F82, but instead chose to use a slightly older but larger version I put away  in May in case this happened again - which it did!!
