Pinned Spreadsheets in the list disappear

[Simon321]

I have a number of pinned spreadsheets within Excel. When I click Open, within Excel, the pinned spreadsheets are at the top of the list. I do this so I can quickly open them. However over the last few months spreadsheets keep disappearing. The same happens in Word. It would appear that Microsoft must have something that says if I haven't opened the spreadsheet in a while that it should not be on the pinned list. How do I stop Microsoft removing items from my pinned open list with Excel?

Thank you

Do you use some kind of "cleaning" utility such as CCleaner? If so, make sure that it doesn't "clean" Microsoft Office/Microsoft 365.

Hi@Hans Vogelaar thanks for the reply but I do not use CCleaner. I have anti virus software but that is it.

Not all the pinned files disappear just ones that I think I haven't used for a while

Weird... Do you use different accounts or just one?

I only use one Microsoft account

I'm afraid I don't have a solution for you. While searching for possible causes, I found that this is a fairly common problem, without a clear pattern...

Thank you. I struggled to find any references to it but I really appreciate your assistance.
