Users Missing from Exchange GAL

Hi All,

There has been situations where users are missing from Global Address List.

I myself  have faced this a few times now. In our environment it only happened when user was rehired.(re-enabled) –>(this happened rarely but when we researched a bit ,finding was –> user was re-enabled)

So thought of sharing the solution which is very simple but is not known to many.

just run the following command

Update-GlobalAddressList -identity “Default Global Address List”

Better to run this command during off-peak hours as for big enterprises it can take long time to finish.

There is one other situation Where user has different email address displayed in email tab(exchange console) & different in email tab of AD  console.

We first resolved that issue & than ran the above command to update the user in GAL.
