Error: channel xxx, master yyy: UIDVALIDITY genuinely changed (at UID zzz). (fixed)

[Seb F. <seb...@gm...>]

Hi,

I suddenly got this error:

*Error: channel xxx, master yyy: UIDVALIDITY genuinely changed (at UID
zzz).*

Here is how I got around it, in case it's useful for others:

1) Locate the offending UID (zzz) in .mbsyncstate in Mailbox xxx/yyy - find
zzz in the first column and note the corresponding local ID in the second
column
2) Locate the message file in the Mailbox (ls | grep "U=id", replacing id
with the ID found in step 1). Move it out of the way, e.g. into a temporary
directory outside the Maildir
3) Run mbsync. This yields a message
Notice: channel xxx, master yyy: Recovered from change of UIDVALIDITY.
4) Move the offending message back into the Maildir
5) Run mbsync again.

Is there a better way of doing this?

Seb.
